- #Koenigsegg has been hard at work creating an engine without a camshaft. Christian von Koenigsegg founded the #FreeValve subsidiary and now has released a detailed video describing its advanced new engine
the day will come when you just download your cam profiles lol
right after 3D printing the heads
why download cam profiles when optimal profiles will be computed in realtime based on engine feedback, demands on the engine, etc...
even during an acceleration, the valve operation can be modified from one cycle to the next, and varied to be optimal for the rpm, economy needs, etc... for every revolution of the engine... every detonation of the air/fuel mixture
You still need a map for the computer to use to determine those perfect openings. Without a map, it would have to be analog and work on a symbolic circuit to give proper ratios.
12rpm :)
The Brown Garage yup! just download the app & tune cars😆😆😆😆
I guess that means VTEC is always kicking in
Came down here to make a vtec or vanos joke. +1'ed yours instead.
YO
Alex Riehm ahh yeah, VTEC FTW
I don't know if FREEVALVE is the same technology as VTEC.
Crecimiento Vtec runs dependently on a camshaft to work
Its hilarious how many people say "cool, but what if it breaks? then it'll cost money to fix." As though current engines are completely free of faults and free to fix.
Might even be easier to swap on bad valve on this set up than on a standard set up.
yes but i don't think that will be even remotly as reliable as some engines are.
This will make engines a heck of alot more reliable than current camshaft engines...and will make it VERY easy to perform valve work
Until real-world durability tests are done, you have no idea how reliable they will be. Vibration, heat-soaking (as in turning off a hot engine in summer) and freezing (as in below zero degrees F) thousands of times in between being run for the equivalent of 150,000 miles is the reliability test, not computer programs.
Everyone knows how rare it is for timing belts, chains, gears and camshafts to fail if they are maintained, that part of your claim is ridiculous. Fewer moving parts is not a guarantee of durability (as seen in the many times higher percentage of Tesla drive failures that require replacement before 100,000 miles versus the engine/transmission combination of any major manufacturer).
George Ford i completely agree with you, but i don' t think this technology will improve durability either, what it will improve is EFFICIENCY. Though if a timing belt rips apart you can buy a complete new engine. if the freevalves fail, they will most likely just stay closed and its no big deal, i guess. i wonder how it will improve gas mileage though
Thanks for this video. Now I can build my very own Koenigsegg
Reo shuレオ周 great idea 😂😂😂
rien smeets o shit he’s Chinese too he isn’t lying
@@bruhdabones right thats why companies don't like to share working process on youtube 😐😐😐😐
HD Tech & Photography or share in general. Trade secrets are better than trademarks as long as you keep your lips shut and aren’t too big. Because while trademarks are enforceable they’re also public and some companies can skirt around the rules.
China: *its free real estate*
So basically they replaced the camshaft with a computer
As for someoe who has the money to buy a koenigsegg, they do not care if this breaks, you won't see an agera with 200.000 km. I just hope this concept doesn't apply to affordable cars because it will be a nightmare.
Yep
@@XxXGamingGuy7XxX why would it be a nightmare?
@@dustinmyeye8752 costs of repair will be astronomical
@@XxXGamingGuy7XxX it doesn't have to be but for this luxury sports car yes it will be.

Hahaha
Nice, now i will try to play in 2x speed of every video with background music
Whole of internet thanks you ❤️
Wooow. Is this an easter egg or coincidence?
Someone already swapped this in a 98 Honda Civic
I dont doubt it
I am pretty sure Koenigsegg has been testing it on a regular mid 2000's commuter sedan. I believe I saw a video of it.
Koenigsegg put a Freevalve head on a Saab 9-5 Turbo for testing, not a Honda.
@@acb5015 would honestly not suprise me, these valves should work on low end cars aswell as long as u install the electronics for it.
And put the 2jz in to a koenigsegg XD
Impressive. I always thought that more electronics are just prone to more problems but this seems quite simple. And plus, less revolving parts driven from the crank, more power to the wheels on top of the efficiency of this system. Hats off to you Mr. Koenigsegg!
Design didn’t stick around nor evolve lol rip
This is actually extremely simple. And just like the 9 speed transmission on the Jesko, Christian must have said "how has no one done it before?"
This
Perhaps many engineers already did and found serious flaws with this model, so they abandoned it.
And Koenigsegg still noob to this kind of stuff, so he thinks he innovates
Sylinoids go bad. A cam and will last a lifetime. It's great for a super car though. I wouldn't rely on 16 sylinoids for a daily driver especially for travel . That's 16 more pieces plus loads of electrical stuff that can and will fail at some point. I wonder what the weight difference is and the load it takes is the engine and its add of hp. I mean if roller rockers add hp. I cant imagine what deleting the whole valvetrain would add. Tons
@@northwestendurogopro503 even if a solenoid fails it will probably fail to the up position and just illuminate your check engine light (not destroy the engine)
@@sauercrowder that's a really good point. If it does fail , it won't be catastrophic. Timing chains break all the time
If it were any other company I'd laugh, but Koenigsegg engineering hasn't misstepped much since inception.
Lorendrawn yeah this looks brilliant, and just the right company to introduce the technology! imagine! variable cam profile, in real time, that can change in real time to give the best fuel efficiency and give the best power, based on whats going on
Well sort of. There is an inherent problem here though. If they can advance this technology to work with standard valves it will succeed with thunderous applause. If it can't use factory valves then that means that a new cylinder head would have to be used. See the problem?
It’s the shear force they are getting out of 3 cylinders on these engines that’s impressed me. When your pairing with twin turbos you can really control pressure efficiencies and scream out their engines.
Pneumatic valve control isn't new, it been around forever. It's really expensive compared to standard cam in block or overhead can tech.
All thanks to ford for helping them find their way, konig used their flat plane v8 as a starting point and decided later to start from scratch
Koenigsegg is the future of motoring.
If they can make that engine on a large scale and produce a new car for the normal consumers, they would dominate the market. I'm a huge fan of their work.
he means "normal cars" not "super sports car"
ok
Martin Sibara me too
shutup!
Music ?
Christian Von Koenigsegg is a freakin' GENIUS!! He is undoubtedly the most creative, passionate, and daring car magnate that ever lived, and my dream is to one day own one of his creations. We're living in great times people.
+Henrik kk You must know Christian I assume..?
Henrik kk Haters gotta hate I guess. Enzo was the force behind Ferrari that pushed them to win like they do. Gates was the leader behind the mega-software company that dominates the industry. Jobs was the man behind the world's most innovative electronics company.
All of these companies had very talented and intelligent engineers and scientist working for them. But without a focused, determined, knowledgeable leader, they would NOT have achieved the success that the have. Christian does not have to be the brightest, most intelligent, or even the most creative...all he needs to do is what he HAS done; lead from the front and get great people to believe and follow you. He has a vision...they implement his vision. He has ideas..they make his ideas into reality. He sets a goal...they do everything it takes to attain that goal.
What have you done, and who follows you?
Henrik kk No sir, I didn't copy anything you stated...we don't agree on anything. There's more to being a genius than creating, engineering, etc. Einstein was a genius for his assumptions and hypothesis, but it was other scientists that PROVED his beliefs.
You sir, are simply a jealous technician under the false assumption that all credit should go to the scientists, when many times it's the dreamers and visionaries that play the largest part. You may be able to figure out how to do a thing, but before the vision was shared, you had no direction to focus your skills. Stop wasting your time hating, instead learn to appreciate what others bring to the table, dude.
Henrik kk Oh please. Dude, you're obviously jealous and negative. Go away with that attitude...no one will ever follow you.
EDIT: By-the-way, another reason why people like you aren't successful is because you get too caught-up in your "education" and titles. People like Mr. Koenigsegg and Mr. Gates just get the job done regardless of their titles, education, or lack thereof. While you're boasting about your diploma/s, they are building companies and smiling at their bank accounts. Now go away, dude.
it was the best of times, it was the worst of times...
same concept of a fuel injector but used for valve train... I love it
I hope those will last longer than fuel injectors, cause the cost for changing them would probably render the technology too expensive for most vehicles..
Like injector pumps combo (not sure this is the correct name in english) nice idea but too expensive on the long run
Am I the only one who's kinda surprised to see...
An Inline 4....
there are hypercar that still uses 4 cyl engine like the porsches
Inline 4 are best power plants.
It appears we had overestimated the cilinder count...
It has 600hp
Didnt they say it was a 3 cylinder?
I remember reading article and 1987 that was regarding the variable valve timing that was in the Honda (Acura) NSX. One of the topics covered in the article was regarding the future evolution of valve timing may someday be electro-magnetically operated valves. . . . It's nice to see such 1980's science fiction become reality.
This technology is not new in engines,only un street car ones,they have been using this technology on F1 since the V12 era
Sean Hollingsworth I don’t know if you ever heard or seen the 80s anime Akira but in that movie,the futuristic bikes made 200 hp. Most bikes in the 80s can only make no less than 140 hp, and now most liter bikes can easily made over 200 hp, like the Ninja H2R that makes 326 hp with supercharger, so that is really cool.
wow so many Internet automotive engineers. perhaps you should work at Koenigsegg and show him how is done?
I AM an automotive engineer !!
Engine development, to be exact.
Still sticking with camshafts for now ! I think BMW tried solenoids in the '90s but they couldn't get them above 3000 rpm or so.
@@lewis72 I'm in the course aswell me and my teacher were talking about the freevalve and the BMW solenoid, solenoids cannot handle large current thats why it didnt work these however are pneumatic driven valves not solenoids.
Yea man internet engineers knows best
Already did, but he will not listen. This aggravates me greatly.
I'm also a 7th degree Black Belt in Feng Shui. Yes, I have the touch of mutherfuck'n DEATH GAW'DAMMIT!!! (eeeeeeeevil chuckle)
I did. They do it my way now.
I wanted to bitch about rotary being the camless engine, but the reduced fuel consumption and (low end) torque made me shut up
+ThePowerfulGameman #NoHate
Its because the computer can change the opening times etc., great idea will be "fire" mode that will force the engine to spit flames out of exhaust, that will be amazing lol!
+TheMineMistrCZ fake anti lag has never been easier!

ThePowerfulGameman good
haha i know right gotta love the old wankel motor
Pneumatic vales have been applied in Formula 1 for quite some time now. About time it made its way onto public roads!!
+Qgal5kap123 The formula 1 system still has camshafts. The difference with them is missing the valve springs which is where the pneumatics are used to transfer the cam lobe pressure to the valve.
Just chiming in to be that guy: How do you know the difference between hydraulic and pneumatic but not your and you're? : P
lolwutbrostahp
Mark J zero people read the homework you typed
Obviously, given the 9 thumbs up on the post, you are incorrect. YOU did not read it.
Advantages:
No Timing belt, and replace every 100.000KM,
No Timing belt synchronization,
No valve calibration,
No mechanical energy lost to engage the valves, (more efficiency)
Easy diagnostic, (dont need dismount the engine to cheek problems),
Less moving parts inside engine, (reliability)
Disavanteges: unknown (too early to say)
Probably each valve will be expensive to replace (like modern diesel injectors) and the electronics will be prone to breaking after long mileage
There is only 1 disadvantage that is crucial and it is the reason this still is not implemented 4 years later, its reliability, timing chains and belts don't go wrong that often, electronics do, if one of the valves fail the engine will be destroyed, and best case scenario it will stop running. Keeping the electronics alive and working 100% of the time is very hard thing to be done
i had to disagree, In case of that valve fail, (dont open) dont have any engine damage because the valve is locked closed by very hard spring, the problem is when the valve is open in wrong time (bad synchronization) that wold make the head of valve crash against the head of the piston, but with Electronics thats impossible, in case of valve bad function the ECU will not let the engine startup to avoid damage, unless you replace the damaged valve. Sorry about the big text :)
I would say the disadvantage wouldn't be on the vehicle side, but on the technician side. Technicians who've mastered timing belts, chains, and camshaft timing would lose a fair amount of business and money with the Freevalve system. However, a little bit of re-education, and that same tech can master Freevalve about as fast as they mastered engine timing.
Cons: Air leaks, oil leaks, solenoid failure, bending valves, broken valve springs, expensive repairs, misfires, circuit board failures, depending on the compression rating of the spring you may need a steady supply of 200-500psi air pressure which is a huge demand for a compressor and can cause failures. Outside temps whether high or very low may effect the system etc etc.
Awesome job by the 3D artist!!
Imagine the 3D artist making the same type of thing but with a grilled cheese sandwich 🤔😮
There was no "artist" in the traditional sense here. The parts are created in an 3D engineering "CAD" software before they are manufactured, so effectively all they had to do was export that file.
@@IFearlessINinja i hope you're kidding, working with cad is art
BigSalo I hope you’re kidding. In its most abstract form, anything is art. But sparing the uselessly broad, cad models are created by engineers, not artists. We design parts such as engine components based off of geometric and material demands, very unlike art which is purely for aesthetic pleasure.
No artist redesigned this part for aesthetic pleasure. This part was engineered purely for performance, and the animation was created by exporting the file. The same creator did not use the same skill set as a 3D artist making a hyper-real grilled cheese schematic
I'm sorry you see it that way. Just because an image is made woth more control than a pencil and a paper it doesnt mean it loses its artisitc properties. To each his own opinion but i'm guessing a 3d modelist cant make art then. Videogame modelist, and yes also engeneers. Its still an expression of an idea in an artistic matter
Watches video with no car knowledge. Pretends to understand what's going on... Slowly clicks away to another video...
And that's how you learn ;).....
Usually pistons drive the crankshaft; via a chain the crankshaft drives the parallel camshaft. The cams are 'timing' bumps on the camshaft that at certain, optimal points of each rev (rpm) will open and close valves that feed the pistons air and fuel to start the cycle again. There are also exhaust valves.
In this video the timing is all computerised and valves are pneumatic.
You know he stopped reading at parrallel right?
Signkutter signkutter I cant read
They say that if you can't explain something complicated in simple terms, you probably didn't understood it yourself. But you explained it in the most elegant and clear manner i can think of. Really well done. Thanks for that.
And just like that, Koenigsegg built a bloody supercar that can jake brake
You're right! That would be a very nice addition.
NEVER understood why anyone would want to use engine braking. as if rings and valves are easier and cheaper to replace than brake pads. DUH!
my aunts 2017 Accord has engine brake it’s strange lol
@@johnmichael1594 enginebraking doesn't damage the engine.
+Cardewi - really? tell me, einstein, what wears out rings and valve guides? engine revs? and if you use engine braking routinely, aren't you putting unnecessary excess revs on the engine? what kind of idiot are you, anyway?
Put this on a diesel engine and you'd get a free Jacob's brake setup through the software ;)
+Kopronko - there isn't enough benefit to put this on diesel engines since they run "unthrottled" for the entire load range
I heard Cat is working on the same thing.
CAT likes to make power and reliability.
Volvo trucks is actually working with Freevalve on putting this in their future engines
PorscheRacer14 Camshafts used to be known as the "brain" of the engine.
Free-tec just kicked in yo!
To think one day some guy on YT recreated this technology on a lawnmower engine and then a Miata, then gives it to the world for free.
it's always nice to see awesome tech being shared for anyone to innovate. more brains = more power!
yeet
How to fuck up a mechanic: Bring one of these bad boys in
Thurnis Haley just send an autosparky
Looks like 100 more reasons for my Check Engine light to come on haha
GregDaGoblin updating your freevalve antivirus regularly would keep it in optimal health.
Oh..so we completely disregard the fact that it saves gas and increases performance?
Nice thing with this design is if an actuator breaks, the spring holds the valve closed so the piston doesn’t slam into the valve and wreck the engine. One of these breaks you take the head off, take the broken actuator out and pop a new actuator in. Meanwhile a cam requires rebuilding a significant portion of the engine.
@Jo Ke Do you know how much it costs to replace a camshaft? If one of those motors break, you replace that one motor. Not the entire unit like you would with a camshaft. And do you know what happens with your camshaft snaps? The car wouldn't function and you would be stuck on the side of the highway.
In what kind of car do you replace spark plugs every 15000km?
And I don't think it'd be how you think
Fun Fact: You didn't search for this.
I did lol
I literally thought of this when I was 12 years old and I told my dad about it and he said it wouldn't work
Your father is correct, such stupid idea is not reliable.

The piston acts as a valve so yeah it does...

Reed valve
Hello !!!!!!!
Christian Von Koenigsegg is a freakin' GENIUS.ounce again the inovations in the world come from one man with a dream. not a huge corporation trying to make money for there stakeholders......
A friend owned a company that made solenoids that operated the flaps (and other things) on F16's - the operating speeds and pressures were breathtaking.
I'm a retired auto mechanic. I've thought about something similar to this for years. I always envisioned the valves being opened and closed by electric solenoids, but that would require much higher performance than a 12 volt system allows. Not that long ago Cadillac was toying with a camless engine using electric solenoids and a 48 volt set-up and no throttle plate using only the opening of the valves to regulate engine speed. Like how a diesel varies engine speed by the amount of fuel delivered. Now we have this FreeValve method using air/oil actuation. Diesels have used high pressure oil to "pop-off" the injectors for a long time. I see no reason why this Freevalve system wouldn't work reliably. I don't really have a point, it's just fascinating to watch the merging of gas and diesel engines. I knew this would happen one day but, damn, I thought of the basic idea of this nearly 30 years ago. Why is it taking so long?
This is just like an F1 engine which is camless and uses pneumatic valves. That's been around for years but they can probably make it more affordable now.
Wrong. Pneumatic valves means the engine doesn't have iron springs, but it still has camshafts to open the valves. In fact, VVT and VVL are banned in F1.
Renault was the first to develop pneumatic valve actuators in their F1 engines in the mid 1980's.
So much for new hi tech being made today...
Well, no. Renault used pneumatic springs to CLOSE the valves in place of normal springs. The engine still had camshafts to open the valves.
clamless engine + Laser igniters (spark plug alternative)
Camless designs are working technology and is a crucial stepping stone for future HCCI systems. However 'laser igniters' doesn't seem credible.
80386 Still sounds cool, though. I could see it working in a few years.
CaptainD00M it would probly hurt your piston head over time if a laser is going off on an engine going at 7000 rpm the laser is pretty much constant and going in the same place so im sure it would just deform the piston
American Pride Nope, we’re not talking laser pointers here. A Femtosecond laser could be aimed at a point on the piston that would reflect the beam at the same time producing a combustion. The time the laser is on would only be .0000000001 second. That cylinder would have to combust a billion times before the laser is actually on for a net time of 1 second.
Laser ignition is actually a very real possibility, and is under testing and development as we speak.
This is great. Possibly the best innovation since Honda introduced VTEC.
Vtec : Hey, what is the controller ?
Freevalve : arduino.
I've seen a video where someone built a system like this on a Harbor Freight Predator engine, controlled by an Arduino. Don't know how reliable his build would be, and it ran rather poorly because the valve timing hadn't been tuned as of that video, but it did run and certainly has a lot of upward potential.
So if you can run a V12 as a V4 or even V2, how much fuel can you save when you don't need as much HP?
While everything is computerised in an engine, why not the cam timing?
It easily gives more control/tuning abilities with much less moving parts. For anyone saying solenoid failure, it can simply be designed or calibrated to resume a fail safe position thus avoiding a catastrophic failure.
It's not that simple. I'll get into a few things that will explain why. There is going to be some science involved here and some programming and I'll tell you why.
1. You would need a system that detects knock. Standard knock sensors won't work here but I'll get into that in a second.
2. You would need a camshaft gear (dummy) to control the fuel injection. Most systems use the camshaft position to trigger the fuel injection.
3. The standard crankshaft position sensors in modern engines wouldn't work and would need to be replaced to allow the use of Pulse Width Modulation.
4. Plugs would have to be installed in the block and head to prevent oil flooding. Oil needs to be in the oil pan to prevent oil pump cavitation.
5. A whole new program would have to be developed for use of this system and would render your stock computer useless. Fuel injection triggering, ignition triggering, knock sensor reprogramming, mass air flow metering, intake manifold temperatures and pressure, etc. which is all stored in the factory computer.
6. This is the big one. Cylinder head configuration. If they can't use the factory valves then the entire cylinder head would have to be replaced.
I didn't touch on everything and I will acknowledge that, but these are the major hurdles that makes the system so expensive. At some point you have to ask yourself this question. Is it WORTH modifying my engine to the extent where a dedicated build of an entirely new engine would be less expensive and built for the system to work correctly? That is what you need to ask yourself.
Proof of concept and practical engineering need to come together here to make it worth the investment and work for all current engines. Otherwise a whole new breed of motor would new to be built. Does this answer your questions?
Aren't electric engines more future proof?
Shouldn't be much of a hassle to get compressed air from some turbine attached to the exhaust. But I agree. Electric engines are far simpler, less prone to breaking and need zero maintenance. Now, if someone could fix the issue of battery weight and charging times, I'd be on board.
@@Mp57navy And the electricity needed. If England would change all their cars to electrical cars, they would need to build 10-12 new nuclear reactors that are even bigger then the ones they already have. So it kinda comes down to if politicians decides more and new nuclear plants across the world is a good idea, otherwise electric cars can never be a thing.
When everyone thought the gasoline engine was at its peak here comes Koenigsegg to save us all. Also I’ve never seen such a beautiful head design on a 4 cylinder. I love it
Isnt this just a copy of Mazdas solution?
I forsee oil leaking into the electronic circuit...
+Stephen R That shouldn't really be a problem as oil is an insulator. I'm more concerned about motor errors/ malfunctions that end up opening the valve at the wrong times or cycles.
Indeed, causing serious damage... All in all it sounds like a nice idea but in practise who knows.
if driven hard & no inspection that could exert itself nice artistic forms & style to powerplant never the less
+Stephen R Dielectric oil
+Stephen R well Christian Von Koenigsegg's already been running on prototypes for quite a while and he says they're going off without a cinch
The only thing that concerns me about this is the proximity of those electronic boards to hot engine components. But I'm sure they thought of that, and it looks like the intake air will go right under them, so probably fine.
Simply, it's a fully electronic version of VTEC
Freevalve kicked in yo!
Umm...no. VTEC uses a camshaft. How can you have VTEC without a camshaft?
@@joshtheking1772 That is why he said "fully electronic version" In works a way similar to vtec but it's all electronic
@@darkknight097 no, it can choose to open 1 or both exhaust Valve to open, a vtec cant do that
Only problem is, if the pneumatic motor sticks it will destroy the whole engine block and head at high load which is to be expected of this engine.
Hmmm Yes at 255mph that be horrible
Hmmm Yes Yes same thought
These guys are really at the forefront with insane ideas. Love it❤
Electronics? Right next to gaskets? Hope they aren't too fragile.
Apart from that, it sounds great. Not only being able to reduce to amount of components in the engine and make it more simple, but also made it stronger.
i dont think oil is conductive
@@guguigugu You are right, it is not.
I worked at a CarQuest store yeara ago and my boss talked about this being in development. He said that it could eliminate the common starter motor that we have used for decades. The concept was explained that when you hit the starter button, the onboard computer looks to see which cylinder is at or just past top dead center, then causes the fuel injector for that cylinder to fire a double shot of fuel before igniting the spark plug. The idea is that the charge is sufficient enough to cause the crank to turn over and start.
The worst design ever
Any electronics failure will lead to engine instability
Wow I'm sure the engineers at Koenigsegg havent even thought of that.
@@budrobadre
it is not just speculation
I am an Electronic Engineer working in Satellite industry
and I know very well what an "Electronic Failure" means
we lost satellites for bad soldering of a capacitor
I am sure they think of that mister budro
@@Soho9111 Any electronic failure will lead to engine instability in ANY engine
Other engines have electronic failures too.
I always knew someone would use solenoids to replace cams.. didn't think it would take 10 years since I had my first engine chewed a valve cause my timing chain snapped.
Matthew Zerafa .. just as yourself this very concept was in my mind - at the time i thought Lotus might have done it first, as they was working on a cam'less engine 15+ years ago. So there you have it, variable valve timing both on lift and duration, all controlled through an ecu - a well and fully tuned engine to suit every occasion.
Imagine downloading some random file called “10K RPM high section for nissan 1.6 lt” and installing it on your valve train
No need to - any car that came with this from the factory would have optimal cam timing for all conditions, no reason not to. Cam profiles are a compromise between various factors, stock cams are made for torque and economy and people put in aftermarket cams that sacrifice that for performance. With this, no need for compromise. Only thing one might do is increase the rev limit.
An engine without camshafts...
You are way too late. Its been done a long time ago.
Its known as a 2-stroke engine. 😁
because we're gonna run our cars on chainsaw engines & get half the compression
Old saabs
@@mikeb2496 One of the old Saab 2 strokes also went to Speed Week several years ago to attempt a new record for its class. Dont know if they succeeded though.
Yeah but a two stroke has a fixed intake and exhaust profile. This one is infinitely variable through the electronics. Changing the two strokes timing would involve machining the ports when this engine shown can do it on the fly anytime to suit any situation, air density, temperature, engine load, etc
@@roochiecooch *Ahem* Power Valve. There is variable exhaust. The intake doesnt take in max CFM untill the engne speed has reached its limit, so it is arguably variable intake. For conditions, load, etc, that can be taken care of with an engine management system. It is true that this offers a more varied induction setup that offers much more adjustability.
But, Im a 2-stroke fan. 😁
very, Very, VERY interesting....I like it....Now,...will it work 150,000 miles from now?
So stupid that this had to take so long to be invented.
I always wonderd why it had to be machanicaly. With electronics you can make it more precies.
Just like the variable head lifting system to make the cilinder longer or shorter. For more compression.
There are also more then 1000 octrooi rights for H2O engines and hot water vapor.
Its going to slow the engine changing.
Its 2019 and we stil drive full fuel cars with big consumption.
A lot of small cars in the 90” use 1 liter to 16 km. So stop acting like we made some New and enviroment frendly.
A lot of diesels still use 1 liter to 15 km.
Thats amazing stupid. Like the Volvo hybrid v70
Wonder what Scotty Kilmer thinks of this.
Ninad Ganore, “Still not as (hahahahaha)reliable as a Toyota (hahahaha)”
Imagine this tech on a highly boosted engine 😱😱😱 Engine knock who?
It can probably detect the increased pressures and switch around the valve profiles accordingly
Besides anyone who buys a supercar is probably not into the car tuning scene
Funny to se all the internet engineers. They made this freevalve go in to mass production in chineese cars and their own.
If when the valve fails, it automatically goes to the full closed position, then we can say goodbye to a problem even SIMILAR to a timing belt breaking causing valves to crash into pistons, necessitating a head rebuild.
I feel so fucking stupid. Why did it take us 20 years to stop and go "hang on... why are we driving this with chains and shafts and limiting our performance if we could just let the computer do it instead?"
What would Mr. Otto say about this update?...
Mr Otto: Since 1867? Really? You disappointed me
Now the Gemera has freevalve. 😍
A dude with a miata: 🤔
Well... 2007 I said this will be the way, and everyone said no... Ladies and gents, I what happens when you don't have credentials.... Nothing!
324 products of public education couldn't wrap their heads around it, and were terribly offended....
I am a big koenigsegg fan.. but the fail rate of technical parts is greater Then mechanial parts. Or am i wrong ? 🤔
The only problem I foresee is that this is so dependent on pressurized air that there are probably going to be tons of seals that are going to be needing alot of maintenance.
+jolichja Seals are only damagaed by overpressure! Just make the seals so they withstand 4 times normal operating pressure and you should be fine ^^
+jolichja Also, if the seals fail, the valve would simply just return to closed state, but if a timing belt on a interference-engine fails, the valves collides with the piston. So, would you rather change a seal or pistons and valves?
And most likely, the valves are controlled by a crank-sensor or something, so if you need to tear open the engine you perhaps don't have to fiddle around with getting the correct timing for the valves? I don't know this, but if it is so, it would be awesome! Hope this make it's way into regular cars soon!
haavard1989 Yea, they use the position of the crank to determine the correct timing :D
+jolichja I can see plenty of NASA engineeers commenting. I am surprised you are not working for Koenigsegg
***** So if you could get 10% more power in the low and high end of your reband that the gearbox can achive it wouldn`t outweigh the cost? This will be first introduced in High end cars and race cars...as always!
Can you just imagine the repair bill, every time you have a solenoid(s) failure you have to pull the head. This engine could work, if GM don't get ahold of it.
Sounds About right
I'm not disagreeing that it would be expensive as hell to fix. However, pulling the head would be much simpler. No chains or cams to align with cylinders
Give it to the Japanese.
If you need to change the actuater you just pull the valve cover.
If the spring fails you'll just end up with an unscheduled rapid disassembly so making that part serviceable isn't too necessary.
@ John Clamshell SP
You're a dumbshit, and that's it in a nutshell, clamshell!!! LMAO!!!!!!!!
I thought of Idea camshafts with lobes half circle shaped with compression bars in them like a wankel rotary engine. Two camshafts a cylinder head. A cog on the ends of the cam shafts with a timing chain or belt connected to the crank. It would take two of this style cam lifter combos per cylinder head one for the intake side and one for exhaust side and porting for both. But it seems simpler and more reliable than the lifters, pushrods, valves, valve, valve seat, and springs. The cylinder head will have ports for the exhaust and ports for the for intake fuel mixture and certain timing in the design of the ports and half circle shaped valves with compression bars spring loaded in them. Making a tight seal for the intake, exhaust, and combustion cycles ????? It would be a camshaft valve combo like a rotary engines like somewhat with three sealing bars on the half circle valve for a air tight seal. Half spherical valveS on the cam shafts with porting and spun by a timing chain that connects the cam shafts to the crank shaft. Plus a oil passage way jacket cam cover that lubricates the camshafts valve combos, and if there is timing chain at the end of cam shafts that oil passages to lubricate it also. I named this type of valve camshaft combo cylinder heads a DV Dual Valveshafts with Half Spherical Valves. I made a video of what I am talking about called "new engine design camshaft (valveshafts) valve combo concept". The camshafts in this design I will have to name valve shafts to be more precise.
What happens when an actuator fails ? You'll be battling Koenigsegg for a new $50000 engine under warranty.
Renault was doing this on race track over 25 years ago, so what's the big deal? Yes, Renault used electrically controlled (solenoid) pneumatic valve actuators over 25 years ago and the racing engines could rev to 20,000 rpm.
This video is an insult to the intelligence of people who follow and understand engines.
This video was obviously made by marketing wankers with little technical knowledge.
They did not use it on a race track, as it never ran in any sort of race car. Question is whether they even tried it in any car of any kind or only test beds. Nobody but Renault knows, but it probably wasn't very successful since they haven't pursued cam-less motors for at least 15 years.
Frankie Teague No they certainly didn't, where do you guys get your misinformation from?
Wow....just yesterday I was dreaming of such an engine in my head but to apply it to a Harley V-Twin.
deescribe
ship engines are using
cam less
electronically controlled
valves , I believe for
considerable fuel savings
Finally! As many probably have, my friends and I conceptualized no-cam valve actuation decades ago, and now technology is finally able to do it! Cool
adding electronic trash to the internal depths of an engine always seems wrong
COMPLICATIONS ARE NOT IMPROVEMENTS...
guess whos going to repair it.... your wallet.......
Exactly. The simpler the better is a good motto for building an engine. Adding complexity can only add more problems. Looks at engines like the Caddilac northstar or many mercedes engines. You try to make something smoother or more powerful by adding a ton of complexity, and you greatly sacrifice reliablity. I guess some cars its not the main concern though. I doubt anyone buys a super car that expects it to do a ton of miles without maintenece.
This engine is simpler than a DOHC. OHC and OHV can't have 4 valves per cylinder.
This is what F1 engines been using for decades.
No. F1 engines have camshafts.
How much will a repair cost if something goes wrong?
A solution to no problem. My old toyota 4age 20 valve blacktop, is still running strong after almost 20 years. I drive it hard passing 8300 rpm at times. Zero faults.
It's not a solution, just an improvement. Lighter, more efficient, better torque and power. Maybe your car is fast enough and fuel efficient enough for you, but this is a better option that now exists.
Nissan was supposed to come out with this tech a over a decade ago. It will not hold for long periods that is why nissan quit on it. There is another way to it thought.
Build a little 4 cylinder with 13:1 compression, a rotating assembly capable of a reliable 10,000 rpm, top it with a cylinder head that flows 300/200 cfm (intake/exhaust ports) or more and this pneumatic valve system and you could literally have a 40 mpg economy engine that turns into a 150 hp/liter top end screamer that also has lots of low rpm power. Every rpm could be optimized for maximum brake torque via valve overlap, lift, duration and timing events to either bleed off or use that 13:1 static compression ratio. With E85 it could be an all motor 2.0L engine that produces 200 lb/ft from 3,000 - 7,000 with a peak power of like 300+ hp up near 10,000 rpm. And it could still get 40 mpg and make 22" of vacuum when cruising. Put a 10 speed dual clutch transmission behind it and it would make a wicked performance car. I'd love to be on the design team for something like that.
Why skimp on the gearbox? If we're going full technology here give it a performance CVT
This is truly ground breaking for the gasoline engine,cant wait for Honda to duplicate the design and take it mainstream
Wtf are people amazed "2 stroke" motors have no cam or valves and been around forever put in mini bikes go carts lawn mowers weed trimmers etc etc, almost the same thing just a bigger scale. Have you all forget about a rotary engine. Koenigsegg No cam wow big deal.
No just no
This system are used in formula 1 for years
Your analogy is not really complete so not actually true. F1 used camshafts for opening valves, pneumatic pressure for closing, only similarity. This uses electronic actuators for opening, sort of like the water valves on washing machines - an electric solenoid.
You spelled describes wrong c'mon man
Now all you have to do is give me one and I'll show you what you do with it.
Nice. I see this video is a few years old and was wondering if they have made this engine or not? Would be nice to see the real thing.
They made a 4 cyl version
Why are people calling this system pneumatic? The valves are controlled by electric solenoids. Think you can get 6 years and a 100 K miles out of them?
Oh capitalism, you lovely thing
hmm basically a Formula 1 design for a street engine? can rev above 10,000 rpm
Nico Montinola rev is compleet useless
So it’s pretty much electric valves. That would break pretty fast.
Blake Hatton lmao what the fuck would you know?
Bro its electronically controlled but the valve opening is powered pneumatically as it clearly states which means air.
Dylan Hutchison that’s what I said
Blake Hatton yeah but the electronic part is not what powers it, its just what triggers it, its just a signal. The air is handling the all the pressure, so no its not gonna break pretty fast.
So basically you can program in the perfect cam profile for each individual RPM. Perfect! This will increase efficiency due to minimized pumping losses and therefore increase torque all across the RPM range.
so 4 years later... how is this coming along?
They just launched the Gemera with a 2.0 freevalve 3 cilynder 600 hp.
Change the flies but the shit is still the same.
Big deal. I have an engineless cam.
I can't wait to see this in the consumer market, swapping this into other cars makes for some terrifying possibilities. A fully adjustable cam powerband is the way of the future
and Hennessey copyright engine Koenigsegg 🗿

Miata guy is famous now!
We'll see how long those pneumatic spring seals last
Karl23extreme haha
Your New.
There are always springs
What an amazing piece of technology. In the next 10 years, I reckon this kind of innovation will fight an uphill battle for superiority against the best of what electric motors can deliver. What a time to be alive.
