@Brian Evans. No... it’s an engine. It turns heat into mechanical motion... the very definition of an engine. A steam engine is still an engine. A turbine engine is still an engine. A pneumatic engine is still an engine. Feel the discharge air... it’s cold.
the major benefit of the Liquid Piston engine when it comes to Rotary type engines is that they have managed to get rid of the Apex points, which is a major issue for Rotary Mazda owners. By getting rid of them, they can increase the efficiency and power of the block.
It seems that there's still Apex points, just on the other side, the 3 sharp edges, but it also looks like in this design they will wear slower than a regular rotary.

#5 Quasiturbine - This is very similar to a concept put forward in the early 1970s by the Rotarymotive Developments group in New Zealand. RMD was engaged in exploring various rotary concepts, many of them developed from inventions of Mr Hamilton Walker. Most of his patented concepts were based on an oval piston or stator as in this engine. This particular geometry - using a lozenging rhomboid piston - can provide consistent seal engagement between the stator and pistons but that is about all it has going for it. Otherwise it has most of the shortcomings of the common Wankel with high surface to volume, even more complex sealing grid, plus a few extras such as the varying angular velocity of the drive shaft (or the need to add a differential mechanism to take out the hunting of opposite piston pairs) and high mechanical forces at the seals which have to drive the inertia forces as the pistons rock back and forth...........9 out of 10 for complexity
Interesting take. Appearing akin to a square rotary engine, it is my personal opinion that this design should be referred to colloquially as the scrotory engine. Partly because of the s denoting the squared-off look but also partly because it sounds like scrotum and I'm immature so that's funny to me.
This engine has no vibration! It is also a detonation engine opposed to deflagration engine (your regular petrol engine). I wish there would be more development on this engine.
I did enjoy the video. The engines shown in the video were definitely strange. I would have liked to have seen more information about the engines. All in all, very informative.
Yup more moving parts has come to mean "oops more to fail" and that in itself does not usually inspire buyer confidence. Opposing piston though sounds really cool.
The things that Koensigg is doing is truly incredible . Check it out ! The guy is a genius ! Solenoid valve actuation , infinitely variable . He also came out recently and stated that all internal combustion engines will be ineffective in catching the quickness of the EV’s but that hybrid drives will be the best way to go until battery technology catches up . He is a man willing to see what is wrong with what he has been doing . I expect Koensigg to come out with a hybrid at some point now that he has seen what Tesla has done .
@@2sing internal combustion engines are not an inferior form of mechanical energy than electric motors. They both have similar carbon footprints and similar total emission levels from different sources. Electric motors may eventually overtake gasoline engines but both types of motors should be developed alongside each other to benefit from both. We should, however, definitely be focusing on moving away from fossil fuels as a source of energy for both power plants and internal combustion engines, as both engines use the same amount of fossil fuels. (Combustion engines don't need to use fossil fuels to burn, we have other sources of ethanol and other compounds that can work well)
The quasiturbine (No. 5) 1:32 is similar to an engine invented in the early 1960’s by Eton Rajakaruna, a friend of my father, in Hull, UK. He was from Ceylon (now Sri Lanka). He called it the “heart-beat engine”. It was featured in an article in Popular Science magazine in April 1962. He was inspired by a vague idea my father had about the possibility of containing the intake, combustion, expansion & exhaust cycles inside a bag-like vessel instead of using a piston & cylinder. Eton’s design looked very similar to the quasiturbine except the combustion took place inside the collapsible box. He was a proud man & claimed that he’d built the entire thing himself in his kitchen using minimal tools. In actual fact my father made most of the prototype parts for him & he made small changes himself. It never ran because it was almost impossible to seal the hinged corners & sides where the combustion chamber contacted the cam plates on either side. It recently struck me that it may have worked better as a steam or compressed air engine, a point that is also made about the engine in this video as well.
the second one is really interesting. it has issues though. it'd cost a lot to manufacture and build. alignment of the chamber and piston would present great challenges for companies to be consistent. it however, looks like it'd rev extremely efficiently. especially since it combines the physics of a fly wheel into a crank shaft. but one misalignment of the piston or chamber and the thing will explode. damaging the entire engine, while most issues with normal engines are fairly salvageable.
@Marijuana Piranha it's going "fop fop fop" which is what I'd expect the pistons to sound like when they rush out of the cylinders under external drive, not what I'd expect the explosion of an ICE to sound like.
some of these don't follow the "KISS" formula.. (Keep it Simple Stupid), . more moving parts, or requiring very tight tolerances or risk breakage, generally speaking isn't the path to go down. but some look promising
@@Lonestar24 yes, and I think that applies for some of these, that being said i completely encourage new ideas and innovation, you learn a lot from failure along with success. great innovation generally stems from a long line of failure
The KISS method would result is less innovation and experimentation as keeping is as simple as possible eventually would result in just the most basic approaches and nothing ever else would be bothered with thus would loose out on opportunities and/or possibilities.
@@CheapSushi that really isn't true. just because something is complicated doesn't mean it's innovative.. There isn't a KISS rule list to follow, it simply means to not over complicate. for example the soviet rocket program during the Apollo and Mercury days, had many many many small rocket engines strapped onto a large rocket, instead of a few larger engines. One could argue that they simply were trying to go with a more proven design, rather then innovate larger rockets engines, but the reality was they made a rocket with many more moving parts, and many more points of failure, which is what occurred..
I think that rotary is keeping to that formula, not apex seals means better combustion, no apex leaks, probably higher efficiency, and only has one moving part! BEAUTIFUL PLS BRING BACK THE ROTARY
the liquid piston rotory by simple physics is definitely a bit of an upgrade. Its basic physics. The rotor path is smoother and because it uses less forms of motion, more of an in and out AND round and round creates less dynamic internal momentum change=less momentum to change=less rptating weight+a round rotor design would seem to allow different terms of compression.
What happens when the Circle Cycle Engine gets just a hair out of line, and the Pistons slam into the cylinder/s like a sledgehammer into a tin can, wouldn't you think so at least. I'm sure they have researched this and tested it over and over, but it just seems quite farfetched as far as durability and dependability over time. Kind of like when a timing belt breaks on an interference motor , the motor is practically destroyed in mere seconds, maybe the same thing would happen with this motor, one simple out of linement and the force and speed would create a destructive chain reaction and destroy the entire motor in under a second at high rpm. Perhaps?
@@Jeremy.Bearemy I mean I agree with you ... I don't think it's the best design for an engine. But to be a little positive about the design, making a smooth chamfer on the cylinder block could help prevent the issue you were describing

If you look at marine engines used on ships, this engine design has been around for about a century. (Not really a concept, but well proven.) Displacements on those tend to be ridiculously huge even when compared to semi-trucks. (You could fit a regular car engine inside one of those pistons.) They just chug along quietly and smoothly.
Yeah, the Commer Knocker was particularly good at converting fuel into noise. Had about 18hp (i'm joking for idiot naysayers) and consumed about the same as 400hp - most of which was converterd to the most sublime very loud noise.
The extra friction and weight of the Infiniti VC engine probably erases most of the improvement in efficiency. The extra manufacturing cost of the monkey-motion linkage makes it more expensive to build and buy, so it probably won't pay off for the user. I predict a short production run.
@ale bob Fifteen years as an auto mechanic has shown me the strengths and weaknesses of every auto manufacturer. 2 years as a Nissan dealership tech made me realize that they make many of the most poorly designed vehicles available.

The 6 piston 3 cylinder engine is basically an evolution of the Napier Deltic, the German Jumo 205 and the Fairbanks Morse 38 8 1/8 submarine engines. Look them up, especially the Deltic, a fascinating and complicated engine.
Notice they cut away the normal spark combustion engine cylinder during the skyactive demo? That's because skyactive is almost literally the same thing just timed/metered more efficiently and works at a higher compression than a typical combustion engine. It is a step above normal combustion but that simulated cutaway veiw was the wrong way to show it because the difference is almost indefinable. It has a crank, pistons, valves (int/exh), spark plugs, works on 4 strokes, the same 4 strokes. It's not a new engine or even new technology. Hundreds of different combustion engines run the same way but with different compression/timing. Maybe it is different and was just explained improperly? But everything I see just shows a normal combustion engine
It is a normal combustion engine. While I certainly have issues when they call it a compression ignition engine, it is none the less an impressive technology. The real impressiveness comes in the fact that they are operating the engine in a heavy knock region that would normally destroy most engines. But they use live cylinder pressure measurement so that the PCM can monitor if things are really getting out of control. We (engine development engineers) have used cylinder pressure measurements to develop engines for a few decades now, but this will be the first application of cylinder pressure measurement in the field (in an automotive engine, anyway)
I think he describes it poorly. If it is what I think it is, then it actually has no spark plugs, but it does instead have direkt fuel injection into the combustion chamber, just like a diesel. Also, running really lean does not stop pre-ignition and knocking, but running richer does, so he has it a bit wrong more than once. Running direkt fuel injection removes the need for stoichometric air/fuel mixture, because there is no fuel to ignite during the combustion stroke. Instead, the fuel is injected near the top of the stroke, just like a diesel engine, and ignites due to the high temperature of the compressed air.
I had to scroll down looking for this comment because I felt the exact same way and didn't want to put it up if someone else already did! That Russel Guy shed a little light on it though!
"Too Complicated!" LOL. Compared to what? Have you seen the inside of a Mercedes DOHC V12? And they run reliably for quite some time thank you very much.
The achates engine design is already is popular use at Fairbanse Morse for their giant diesel engines used for ship power and emergency generator power etc... so its a proven design and extremely reliable. There is really little to no reason not to trim the fat from it and put it in automotive applications. The military is also contracting Cummins to build a 4 cylinder 1000hp tank engine using Achates technology called the ACE (advanced combat engine)... they also have a big 10L engine for freight tractors being tested by I think it was Tyson and Walmart that meets all next generation emissions requirement while also reducing the need for so much DEF.
The have been a number of opposed-piston engines in production. Perhaps the most notable is the Napier Deltic, which had three banks of cylinders of opposed pistons. It's an 18 cylinder two stroke diesel, supercharged. Used mostly for railway engines and in ships. You can read up on it here: en.wikipedia.org/wiki/Napier_Deltic
Quasiturbine: What do you mean, it's too complex? It's the simplest motor out there, it's simpler than a single-piston engine! You just basically need only like 7 parts! It's just that it's spinning.

To me, it sounds like "I don't understand wheels that spin". Come on! Look it up, like it or not, it's really cool. Thanks for mentioning it here. ^_^
The LiquidPiston X is going to end up having the same apex seal issues that all rotary engines have. I also have yet to see a multi-rotor LPX, as all of the ones I've seen have been single rotor with the same triangular shaped intake and exhaust; how would they design for a multi-rotor, or even a design for a more conventional intake and exhaust? Having the ports spaced around the shaft makes things more difficult, and a multi-rotor would have an odd design of intake-rotor-exhausts-rotor-intakes, or for 3 rotors it'd have to be i-r-e-r-i-r-e, and the piping for that kind of setup would be insane. What about chargers, with six inlets, and all the piping that comes with them, you'd end up needing some hefty charging equipment when compared to other engines. Wiring is another issue considering all the plugs are also located around the entire engine. Also the difficulty of machining the rotor is questionable. There's also the fact that LiquidPiston disappeared for years, then came back just to disappear again, and last I know, nobody really knew why. Either they got a good contract, or they ran into financial issues. Of all the new engines, outside of mass-production ones from large corporations, LPX is one that I would've hoped to see come to market and actually be decent. It'd be nice to have a modern rotary, other than being used as a hydrogen fueled range extender for electric driven hybrids, but I don't think we'll ever see one at this point. Hopefully someday LPX will have more than just a single rotor to show off, but I have my doubts.

I think the major advantage is that LiquidPiston X, can have higher (compared to Wankel) compression ratio due to geometry. And because of three combustion chambers, the temperature of the housing should be more uniform, that alone should improve seal design. So, overall it should be better than Wankel. Sure, the seals will be wearing off, but it is not that a big deal, and they can last years I guess. The biggest issue would be a lubrication of the seals, and emission issues.
The resolution to all the issues you stated above, are the same as for any Wankel... intermediate castings between rotor section to unify plumbing, and ceramic apex seals. Problem solved. NEXT!
@@driverjamescopeland the issue with intermediate castings on the lpx is how you'll route six ports to a single port for a header, the piece itself will end up being larger than the engine with that much complexity. Also, ceramics are nothing new, you would think that, if they're effective, they would have been extensively tested and used. In your absolutely annoying, and toxic, words: Next!
@@xaytana The improvement on the apex seal front, from LiquidPiston's own statements, is that you can cool them much more effectively because they're in the housing rather than on the rotor, which should make them last a lot longer, and because they're not moving, the tolerances can be better and require less lubrication. If this actually turns out to be the case, it could be a really useful engine.
Bob Lazaar has it hidden somewhere in his underground garage, but don't tell the feds, they'll send nineteen hundred agents from twenty seven different agencies, just to look for it 🤣
I've had an idea for a motor for the past 30 years but never did it. After watching this (and kind of expecting to see my motor) I should try to build it.
@@SS-ts4ht What happened after I wrote that 2 years ago? I have a better idea that I think should be mass produced. I tried making the parts but couldn't get within any tolerances so I bought a bridgeport milliing machine, south bend lathe, Jet horizontal/vertical 7x12 bandsaw and have been buying steel on Craigslist in the Pittsburgh/Cleveland area and am working towards that goal. Surprised I got asked. I don't think anyone believes I can do it. But I'm trying.
Nothing will ever be as great as the overhead valve, pushrod V8. I grew up a big time gear head and I recall reading a very technical book about engines where the author explained that if engine technology had continued to improve at the rate it did from the 1940s-1960s, then today's small block Chevy would produce north of 10,000HP and 15,000ft/lb and last for 25 million miles
A number of these have practical potential ! Like you, I would like to see more actual hard data on them before I make up my mind. We are a small engine repair facility, and would love the opportunity to test a few of the smaller engines in real world application ! The chainsaw, and the Go-Kart definitely have our attention !
Very interesting designs... The simplest and probably the most efficient one is the Liquid Piston engine... The power to weight ratio potential of this Liquid Piston design is also quite impressive... The Wankel Rotary engine was a very innovative design, and they had tremendous potential, but they had some serious inherent problems. The 'Liquid Piston' engine design seems to have solved all of the inherent problems of the Wankel design, with the high power to weight ratio and what appears to be extreme reliability and simplicity...
A vast majority of these are already obsolete and will remain so for years if not a decade before they would have been used, if not for electric motors and hydrogen fuel cells that will offer higher range, lower maintenance cost, and above all else, nearly zero moving parts outside the generators themselves.
@@Anon54387 electric cars have been around for a very long time. They are not "new". Neither are the wind driven generators. A large number of the big station properties here in Australia had wind generators, with back up 32 volt DC generators which were driven by old Lister engines, or the Villier's engines. Some had the big Fairbanks-Morse diesels. With renewable power, the only relatively "new" player is solar power, though this have been around for more than 30 years now. Just something worth thinking about is that no matter what power systems, or vehicles we use, we need the oil industry!! The reason is very clear. All vehicles need lubrication for the wheel bearings, along with oil in the differential, & motor bearings. You can laugh at my comment, but you will soon realise I am correct.
Should make a video about new winding techniques for electric motors, new magnet technologies, transformer rectifiers, batteries or big capacitors. We are not going to be using gasoline much longer. Also the hall thruster was very cool.
How can we make a simple crank and connecting rod more complicated and way harder to work on while simultaneously achieving almost nothing, increasing cost and decreasing reliablility? Infinity: I'm bout to end this mans whole career
4:25 is my favorite it sounds like a standard rotary engine but lighter stronger and more efficient and easier to make. Also if you add additional side seals to the rotor and then put a hole at the center line with the "Apex seal" between them you would have decided oil to them and then all you have to do is put a little oil bleed in front of the "Apex seals" and you are done.
Correction: Rocket engines and other space propulsion systems do not have a "maximum velocity" they can reach, rather they have a maximum efficiency they can achieve. in theory, for a given payload of weight Mp, any type of thruster (chemical, ion, or otherwise) can reach any velocity, it just takes a different mass of fuel, Mf, to get there for engines of varying efficiency. The efficiency, Isp, is measured is meters per second, however its not actually referring to a literal velocity, it's just how the units work out (sometimes its referred to as effective exhaust velocity, but this is just a name, and a confusing one at that). What Isp really represents is the amount of force generated for each kg/s of fuel flow. On any engine, if you increase fuel flow, you increase thrust. But the better the Isp, the more thrust you get for that increase. Now we have everything we need to find out how fast we can go if we know Mp, Mf, and Isp. To find the change in velocity, delta_V, capable, we use the Tsiolkovsky rocket equation, which states: delta_V = Isp * ln(Mt/Mp) where the total starting mass is Mt = Mp + Mf For chemical rockets, the theoretical maximum Isp is around 5,000 m/s while the highest recorded Isp of any ion engine (as far as I am aware) was 189,333 m/s from the DS4G thruster developed by the ESA.
The X3 has a failure rate of 0.2/10 and that's mostly just underperformance failures, its just got five failure points and is supercompact. Try that on for size carman.
@@Iamlurking504 Most of the experience we have seen with compact engines (3cyl vw polo and opels etc.) very unreliable compared to older less power dense 4 cyl. For example with diesels: 1.9l Renault 19 diesel (around 60hp) lasts for ever sometimes 800.000km while a modern 1.9l Renault DCi (about 110hp) lasts barely 200.000km!
I dream of the day they invent an engine that runs on cursing and road raging in a 40m radius from the engine. I'll never have to refuel a car again in my life.
It's a shame that opposed piston didn't make it to modern heavy applications. Because it actually has various advantages over a regular 4 stroke. - No valvetrain = less moving parts - Robust mechanism - 2 stroke = better power density - Longer total cylinder stroke = better efficiency - Proven tech on WW2 aircraft and tanks
The "Liquid Piston's" engine looks very promising. It solves few of the issues of the Wankel engine, without adding new moving parts. The efficiency should be higher, and sealing should be easier, due to temperature of entire housing being the same. Achates engine is nice too, but not particularly new. The engines like that were used in the past in locomotives. They are good stuff, and if they can make it small, it can have benefits.
Very intresting but after all I must say sorry they fail because of too much moving parts. The Ion-thruster is probably the one we will use for the proxima centaury exploration.
Wow i didn't know this channel before, and expected a video of the quality of those indian mainstream channels that use clickbait and titles like "dangerous modern big machinery processing" that sound like they just took a bunch of words that sound spectacular and put them in a random order. But i was positively surprised. Thank you.
Actually more common failure point since they improved the seals, is deformed rotor housing since all the heat is generated on one side of the engine. Beauty of the Liquid Piston is it spreads the heat of combustion around the entire housing. But still funny.
Voyager used THE ENTIRE GODDAMN PLANET OF JUPITER as its primary thruster. once every thousand years, the planets align perfectly, and you can bounce a probe off all of them, and get shot into interstellar space at mach eighty billion. inb4 woosh: I know, but it's a fun fact.
I remember seeing a working example of the deltic locomotive engine at a railway museum when I was TDY in England when I was in the air force! It was a way out there design, like something out of an engineer's fever dream involving the Greek alphabet! It was quite powerful and somewhat efficient but a nightmare for those who had to build and maintain it!
The Liquid Piston engine has actually been tested and is able to run on hydrogen 'wet fuel', rather than a hydrogen fuel cell, seen in the Toyota Mirai, for example. That would have the convenience of a fossil-fueled ICE but with zero emissions other than water. Alternatives for fossil fueled ICE engines are going to be the way to go, but I don't think electric motors will be the silver bullet, especially when it comes to other major polluters (airlines, for example), so it's very good that there are at least 2 possible solutions available for use.

...which will however be extinguished, hopefully soon, I would put to the penalty those who still produce internal combustion engines
@@2sing internal combustion engines are not an inferior form of mechanical energy than electric motors. They both have similar carbon footprints and similar total emission levels from different sources. Electric motors may eventually overtake gasoline engines but both types of motors should be developed alongside each other to benefit from both. We should, however, definitely be focusing on moving away from fossil fuels as a source of energy for both power plants and internal combustion engines, as both engines use the same amount of fossil fuels. (Combustion engines don't need to use fossil fuels to burn, we have other sources of ethanol and other compounds that can work well)
The potential of mechanical engines are endless: I'm so hyped up ............... THNX for the video, mate.
Thank you for this awesome list video with 7 items that doesnt take 27 minutes to watch!
Wow, the cycle engine! I thought several times about a similiar concept with magnets. But I am not an engineer. :p
You're an engineer if you make it happen and it works. Maybe not an engineer on paper but who cares about that. Hopefully you try it someday. 👍

that circle cycle motor had me on the edge of my seat lol
The quasiturbine (No. 5) 1:32 is similar to an engine invented in the early 1960’s by Eton Rajakaruna, a friend of my father, in Hull, UK. He was from Ceylon (now Sri Lanka). He called it the “heart-beat engine”. It was featured in an article in Popular Science magazine in April 1962. He was inspired by a vague idea my father had about the possibility of containing the intake, combustion, expansion & exhaust cycles inside a bag-like vessel instead of using a piston & cylinder. Eton’s design looked very similar to the quasiturbine except the combustion took place inside the collapsible box. He was a proud man & claimed that he’d built the entire thing himself in his kitchen using minimal tools. In actual fact my father made most of the prototype parts for him & he made small changes himself. It never ran because it was almost impossible to seal the hinged corners & sides where the combustion chamber contacted the cam plates on either side. It recently struck me that it may have worked better as a steam or compressed air engine, a point that is also made about the engine in this video as well.
Cool story, bro 👍
Go over a bump with No 6 Circle Cycle and everything will go with a mighty Bang !.
All clever stuff though.
the second one is really interesting. it has issues though. it'd cost a lot to manufacture and build. alignment of the chamber and piston would present great challenges for companies to be consistent. it however, looks like it'd rev extremely efficiently. especially since it combines the physics of a fly wheel into a crank shaft. but one misalignment of the piston or chamber and the thing will explode. damaging the entire engine, while most issues with normal engines are fairly salvageable.
1:25 - that's not a running engine, it's being driven by an electric motor. It just proves you can make some things that fit together when rotating.
@Marijuana Piranha it's going "fop fop fop" which is what I'd expect the pistons to sound like when they rush out of the cylinders under external drive, not what I'd expect the explosion of an ICE to sound like.
some of these don't follow the "KISS" formula.. (Keep it Simple Stupid), . more moving parts, or requiring very tight tolerances or risk breakage, generally speaking isn't the path to go down. but some look promising
The KISS principle can only be applied when "keeping it simple" achieves a comparably desirable outcome.
@@Lonestar24 yes, and I think that applies for some of these, that being said i completely encourage new ideas and innovation, you learn a lot from failure along with success. great innovation generally stems from a long line of failure
The KISS method would result is less innovation and experimentation as keeping is as simple as possible eventually would result in just the most basic approaches and nothing ever else would be bothered with thus would loose out on opportunities and/or possibilities.
@@CheapSushi that really isn't true. just because something is complicated doesn't mean it's innovative.. There isn't a KISS rule list to follow, it simply means to not over complicate. for example the soviet rocket program during the Apollo and Mercury days, had many many many small rocket engines strapped onto a large rocket, instead of a few larger engines. One could argue that they simply were trying to go with a more proven design, rather then innovate larger rockets engines, but the reality was they made a rocket with many more moving parts, and many more points of failure, which is what occurred..
I think that rotary is keeping to that formula, not apex seals means better combustion, no apex leaks, probably higher efficiency, and only has one moving part! BEAUTIFUL PLS BRING BACK THE ROTARY
the liquid piston rotory by simple physics is definitely a bit of an upgrade. Its basic physics. The rotor path is smoother and because it uses less forms of motion, more of an in and out AND round and round creates less dynamic internal momentum change=less momentum to change=less rptating weight+a round rotor design would seem to allow different terms of compression.
Do you have any links to forums or sites where people are actually making and testing these? Thanks.
What happens when the Circle Cycle Engine gets just a hair out of line, and the Pistons slam into the cylinder/s like a sledgehammer into a tin can, wouldn't you think so at least. I'm sure they have researched this and tested it over and over, but it just seems quite farfetched as far as durability and dependability over time. Kind of like when a timing belt breaks on an interference motor , the motor is practically destroyed in mere seconds, maybe the same thing would happen with this motor, one simple out of linement and the force and speed would create a destructive chain reaction and destroy the entire motor in under a second at high rpm. Perhaps?
Yeah that seems like it should be on a list of ways NOT to design engines xD
@@Jeremy.Bearemy I mean I agree with you ... I don't think it's the best design for an engine. But to be a little positive about the design, making a smooth chamfer on the cylinder block could help prevent the issue you were describing
The Skyactive engine design has been around for ages.
Think it has promise, that rotary too?
The Liquid piston would be good for power armor where light weight, fuel efficiency and high output power is more important than engine longevity.

@@halipatsui9418 Less reciprocating mass than a piston engine, so I don't think it would be easier to find a more helpful gasoline method

@@Tech_Planet The napier diesel uses that principle too, tho it has been used in railroading.
If you look at marine engines used on ships, this engine design has been around for about a century. (Not really a concept, but well proven.) Displacements on those tend to be ridiculously huge even when compared to semi-trucks. (You could fit a regular car engine inside one of those pistons.) They just chug along quietly and smoothly.
Yeah, the Commer Knocker was particularly good at converting fuel into noise.
Had about 18hp (i'm joking for idiot naysayers) and consumed about the same as 400hp - most of which was converterd to the most sublime very loud noise.
The extra friction and weight of the Infiniti VC engine probably erases most of the improvement in efficiency. The extra manufacturing cost of the monkey-motion linkage makes it more expensive to build and buy, so it probably won't pay off for the user. I predict a short production run.
Nissan can't even produce a simple engine with a decent life-span.

A good rule of thumb, fewer moving parts means better longevity. (Provided parts are made to a set standard)
As a layman, that's what I see: Too many parts, too often something is broken.
True but not always. For example a in linefour cylinder engine get better relatability with a balance shaft than without.
But there are many more important points to consider except longevity. For example turbo engines are likely more efficient than normal motors.
Rotary engine approx 16 moving parts, inline 4 cylinder approximately 100 but no comparison in reliability and longevity over a rotary 👍
@@jimdavis2385 yeah a part is a failure point, that's pretty obvious.
Dude. I love all those engines. Thanks so much for the great video.
The 6 piston 3 cylinder engine is basically an evolution of the Napier Deltic, the German Jumo 205 and the Fairbanks Morse 38 8 1/8 submarine engines. Look them up, especially the Deltic, a fascinating and complicated engine.
Notice they cut away the normal spark combustion engine cylinder during the skyactive demo? That's because skyactive is almost literally the same thing just timed/metered more efficiently and works at a higher compression than a typical combustion engine. It is a step above normal combustion but that simulated cutaway veiw was the wrong way to show it because the difference is almost indefinable. It has a crank, pistons, valves (int/exh), spark plugs, works on 4 strokes, the same 4 strokes. It's not a new engine or even new technology. Hundreds of different combustion engines run the same way but with different compression/timing. Maybe it is different and was just explained improperly? But everything I see just shows a normal combustion engine
It is a normal combustion engine. While I certainly have issues when they call it a compression ignition engine, it is none the less an impressive technology. The real impressiveness comes in the fact that they are operating the engine in a heavy knock region that would normally destroy most engines. But they use live cylinder pressure measurement so that the PCM can monitor if things are really getting out of control. We (engine development engineers) have used cylinder pressure measurements to develop engines for a few decades now, but this will be the first application of cylinder pressure measurement in the field (in an automotive engine, anyway)
I think he describes it poorly. If it is what I think it is, then it actually has no spark plugs, but it does instead have direkt fuel injection into the combustion chamber, just like a diesel. Also, running really lean does not stop pre-ignition and knocking, but running richer does, so he has it a bit wrong more than once.
Running direkt fuel injection removes the need for stoichometric air/fuel mixture, because there is no fuel to ignite during the combustion stroke. Instead, the fuel is injected near the top of the stroke, just like a diesel engine, and ignites due to the high temperature of the compressed air.
I had to scroll down looking for this comment because I felt the exact same way and didn't want to put it up if someone else already did! That Russel Guy shed a little light on it though!
"Too Complicated!" LOL. Compared to what? Have you seen the inside of a Mercedes DOHC V12? And they run reliably for quite some time thank you very much.
Damn I saw a rotary engine so I though of a new way to make an engine, then found this video and the arches 2.7 is what I was thinking of trying 😂
The achates engine design is already is popular use at Fairbanse Morse for their giant diesel engines used for ship power and emergency generator power etc... so its a proven design and extremely reliable. There is really little to no reason not to trim the fat from it and put it in automotive applications. The military is also contracting Cummins to build a 4 cylinder 1000hp tank engine using Achates technology called the ACE (advanced combat engine)... they also have a big 10L engine for freight tractors being tested by I think it was Tyson and Walmart that meets all next generation emissions requirement while also reducing the need for so much DEF.
The have been a number of opposed-piston engines in production. Perhaps the most notable is the Napier Deltic, which had three banks of cylinders of opposed pistons. It's an 18 cylinder two stroke diesel, supercharged. Used mostly for railway engines and in ships. You can read up on it here:

Quasiturbine: What do you mean, it's too complex? It's the simplest motor out there, it's simpler than a single-piston engine! You just basically need only like 7 parts! It's just that it's spinning.

The LiquidPiston X is going to end up having the same apex seal issues that all rotary engines have. I also have yet to see a multi-rotor LPX, as all of the ones I've seen have been single rotor with the same triangular shaped intake and exhaust; how would they design for a multi-rotor, or even a design for a more conventional intake and exhaust? Having the ports spaced around the shaft makes things more difficult, and a multi-rotor would have an odd design of intake-rotor-exhausts-rotor-intakes, or for 3 rotors it'd have to be i-r-e-r-i-r-e, and the piping for that kind of setup would be insane. What about chargers, with six inlets, and all the piping that comes with them, you'd end up needing some hefty charging equipment when compared to other engines. Wiring is another issue considering all the plugs are also located around the entire engine. Also the difficulty of machining the rotor is questionable.
There's also the fact that LiquidPiston disappeared for years, then came back just to disappear again, and last I know, nobody really knew why. Either they got a good contract, or they ran into financial issues.
Of all the new engines, outside of mass-production ones from large corporations, LPX is one that I would've hoped to see come to market and actually be decent. It'd be nice to have a modern rotary, other than being used as a hydrogen fueled range extender for electric driven hybrids, but I don't think we'll ever see one at this point. Hopefully someday LPX will have more than just a single rotor to show off, but I have my doubts.

I think the major advantage is that LiquidPiston X, can have higher (compared to Wankel) compression ratio due to geometry. And because of three combustion chambers, the temperature of the housing should be more uniform, that alone should improve seal design. So, overall it should be better than Wankel. Sure, the seals will be wearing off, but it is not that a big deal, and they can last years I guess. The biggest issue would be a lubrication of the seals, and emission issues.
The resolution to all the issues you stated above, are the same as for any Wankel... intermediate castings between rotor section to unify plumbing, and ceramic apex seals. Problem solved. NEXT!
@@driverjamescopeland the issue with intermediate castings on the lpx is how you'll route six ports to a single port for a header, the piece itself will end up being larger than the engine with that much complexity.
Also, ceramics are nothing new, you would think that, if they're effective, they would have been extensively tested and used.
In your absolutely annoying, and toxic, words: Next!
@@xaytana The improvement on the apex seal front, from LiquidPiston's own statements, is that you can cool them much more effectively because they're in the housing rather than on the rotor, which should make them last a lot longer, and because they're not moving, the tolerances can be better and require less lubrication. If this actually turns out to be the case, it could be a really useful engine.
Thank you for including as many videos as you could.

Very interesting designs... The simplest and probably the most efficient one is the Liquid Piston engine... The power to weight ratio potential of this Liquid Piston design is also quite impressive... The Wankel Rotary engine was a very innovative design, and they had tremendous potential, but they had some serious inherent problems. The 'Liquid Piston' engine design seems to have solved all of the inherent problems of the Wankel design, with the high power to weight ratio and what appears to be extreme reliability and simplicity...

The Infiniti/Nissan engine is the best and practical.
Thanks.
Correction: Rocket engines and other space propulsion systems do not have a "maximum velocity" they can reach, rather they have a maximum efficiency they can achieve. in theory, for a given payload of weight Mp, any type of thruster (chemical, ion, or otherwise) can reach any velocity, it just takes a different mass of fuel, Mf, to get there for engines of varying efficiency. The efficiency, Isp, is measured is meters per second, however its not actually referring to a literal velocity, it's just how the units work out (sometimes its referred to as effective exhaust velocity, but this is just a name, and a confusing one at that). What Isp really represents is the amount of force generated for each kg/s of fuel flow. On any engine, if you increase fuel flow, you increase thrust. But the better the Isp, the more thrust you get for that increase. Now we have everything we need to find out how fast we can go if we know Mp, Mf, and Isp. To find the change in velocity, delta_V, capable, we use the Tsiolkovsky rocket equation, which states:
delta_V = Isp * ln(Mt/Mp)
where the total starting mass is Mt = Mp + Mf
For chemical rockets, the theoretical maximum Isp is around 5,000 m/s while the highest recorded Isp of any ion engine (as far as I am aware) was 189,333 m/s from the DS4G thruster developed by the ESA.

It's a shame that opposed piston didn't make it to modern heavy applications. Because it actually has various advantages over a regular 4 stroke.
- No valvetrain = less moving parts
- Robust mechanism
- 2 stroke = better power density
- Longer total cylinder stroke = better efficiency
- Proven tech on WW2 aircraft and tanks
The "Liquid Piston's" engine looks very promising. It solves few of the issues of the Wankel engine, without adding new moving parts. The efficiency should be higher, and sealing should be easier, due to temperature of entire housing being the same.
Achates engine is nice too, but not particularly new. The engines like that were used in the past in locomotives. They are good stuff, and if they can make it small, it can have benefits.

Always good to see new ways to help the planet
More parts = more problems.
Rotary has less parts but they're full of problems ;)
A good statement on the IC engine.
a battery has no moving parts, and it sucks
ha gottem
2:13 A compressor running another compressor.... that's not an engine
liquid piston
What particle program did you use to make the particles?
You should've mentioned konigsegg's electronic valve engine. That thing is dope
Nah the raptor methalox engine is better.
The Achates reminds me of the Deltic opposed piston locomotive engine from 70's or maybe late 60's.
I remember seeing a working example of the deltic locomotive engine at a railway museum when I was TDY in England when I was in the air force! It was a way out there design, like something out of an engineer's fever dream involving the Greek alphabet! It was quite powerful and somewhat efficient but a nightmare for those who had to build and maintain it!

The opposed piston engine has been around for a looooong time
@Dave Micolichek and german diesel for aircraft using. Jumo 205 &207.
@@matthiaskorn7544 Aaand the Deltic, used in both British navy light assault boats and Deltic Class locomotives.
The Fairbanks Morse opposed piston engine was used in us submarines since 1938! Got to see one in person at Great Lakes Naval Training Center.
wwii era tank engines. some old school heavy duty construction equipment
The old knocker had a truly amazing sound.... I hope they can get this thing right, could be interesting
As much as I love to see innovation and mechanical devices, the truth is electric will probably continue to be the way to go
The Liquid Piston engine has actually been tested and is able to run on hydrogen 'wet fuel', rather than a hydrogen fuel cell, seen in the Toyota Mirai, for example. That would have the convenience of a fossil-fueled ICE but with zero emissions other than water. Alternatives for fossil fueled ICE engines are going to be the way to go, but I don't think electric motors will be the silver bullet, especially when it comes to other major polluters (airlines, for example), so it's very good that there are at least 2 possible solutions available for use.
Cool video, thanks :)
Is this available to purchase somewhere?
dorito power still remains a legend
