That Lanz Buldog with it's Hot Bulb was incredible! Next to it the beautiful Square four - that was a fabled engine even when I was a kid. Aerial made some really advanced bikes and engines: water cooled, Shaft drive, belt driven all way ahead of the time. But for me the Lanz for the win.
@@aeroflopper no, the first video is literally a type 1. the Fuhrmann engine is TOTALLY different. www.venarca.com/wp-content/uploads/2018/04/Porsche_engine_venarca1.jpg It has QUAD CAMS for one, and says PORSCHE on them.
The lanz bulldog, as a hot bulb 2 stroke, is capable of idling at 0 rpm. This is because fuel is injected at BDC. So basically with the throttle adjusted so low that the engine cant overcome compression, it bounces back and forth between TDC in each direction (the engine reverses back and forth never making a full rotation). The fuel is injected into the hot bulb (a heated area that both vaporizes the fuel and causes the white oil smoke to start burning) where it combusts from high heat and compression where it shoots through a tiny hole into the cylinder which causes the piston to move. The tiny path between the hot bulb and the cylinder causes restriction which makes the pressure increase rapidly because of the vaporizing and burning oil which causes the entirety of the fuel oil to combust. This allows a hot bulb engine to have the pressures required to burn fuel oil without needing a high compression ratio. The time it takes for the pressure to build in the hot bulb and move into the cylinder means that the engine has to be designed to run at a limited rpm range. A diesel engine is a modern alternative that uses high compression (double that of a gasoline engine) and injects the fuel using high pressure at TDC into the hot compressed air which combusts it. A diesel can be started cold, but a hot bulb engine needs to have the hot bulb heated cherry red for 10 to 30 minites on even a warm day before it will start.
YUKI JINJUJI Alberto Ruiz is right: the first engine on the video is one of the first Porsche engines that have absolutely nothing in common with model 547. And, historically, Porsche/VW cooperation was official (not copies!) until 1976, with Porsche 914 series.
It's NOT a normal 356 engine and it's not a "tweaked VW". It has ball bearings and absolutely not one part is the same as any VW engine. This engine is RARE. The Carrera engine is not.
This is the type 547 engine. The engine in the video is a NORMAL pushrod 356 engine. The type 547 has 4 cams driven by gears. type550.com/blueprint/car-specs/quad-cam-engine/
That lead-off Porsche motor is NOT a four cam motor as the description leads one to believe. It's a typical pushrod motor of 1500/1600 cc displacement,
The segment on the Porsche Fuhrmann, said to be a DOHC engine, shows what looks very like a VW OHV. It could be SOHC, but, even then, the valve covers don't look roomy enough for a camshaft.
The 1500GS Carrera engines had dual ignition as well as dual overhead camshafts. Two distributers as well as very large cylinder heads. Very different looking from this engine, which appears to me to be an early 356A Normal engine, judging from the flattopped Bosch distributor cap.
@@rescue270 And the single barrels carburetors. Looks like the engine in the 1956 Normal I had decades ago. Except mine didn't have a flat distributor cap.
Aircraft engines which held the crankshaft stationary while the cylinders spun around it weren't uncommon 100 years ago. At that time they were fairly common, and among other things they were easier to keep cool in operation.
You left out the Napier Deltic, which has to be one of the strangest engines made. It's a 3 crankshaft version of the Junkers, and was famous for powering Brirish Diesel-electric locomotives for many years. Strange engine, but it worked!
It was also used in Marine applications. The opposed piston diesel two strokes are mightily efficient. The Napier Deltic proved itself to be one hell of an engine.
That square four engine is pretty interesting, like an upright V4. That Gunbus 410 is a monster to put out 523 lb-ft of torque, and still be a two stroke.
The TS3/"Knocker" is not supercharged, its blown, mechanically scavenvenged twostrokes dont let air through the crank case and therefore use a blower for creating an airflow.
Why are you guys trying to make a misleading distinction between blower-scavenged two-stroke diesels and other supercharged engines? If the pressure in the intake manifold is > 1 atm when the intake port opens, it is, BY DEFINITION, supercharged. Whether it's done by necessity (as in a two-stroke diesel) or just for more power output (as in a four-stroke application) doesn't change the technical definition of supercharging. While the creator of this video clearly isn't very knowledgeable, I'm afraid you guys are the ones guilty of "promulgating ignorance" here.
At the very end of the video is a VERY abrupt and EXTREMELY Loud noise, it only lasts for a moment, but Heaven help you if you're wearing headphones! It took three of my friends to peel me off the ceiling, after which, both of my eardrums now reside in the center of my head!
Do a video on square designed engines if there are more out there, really interested in why that never caught on 40hp from 993cc engine of that age is very decent.
Square, or twin row engines, as a square is in essence a twin row eninge with two crankshafts, I worked on a Sulzer 12LDA28, which is a 12 cylinder twin crankshaft design, it's a large marine/railway diesel engine and engineers thought 2 crankshafts should handdle the vast amount of torque better than a V configuration with shared cranks or fork and blade rods. The idea in the Ariel square four was to get a more balanced running engine, problem was the air cooling of the rear cylinders however, it works better in a liquid cooled configuration.
dieselmupke ye iv seen that these type of engines have cooling issue with being air cooled but as a car engine design and watercooled id like to know why it dont see production version seam to have great power and torque in a non boosted format.
Probably too expensive to use in a car engine, those need to be cheap to make in the first place, and only for top end cars would they go that way. Only application I know for twin crankshaft engines in cars are the BRM H16 racing engines, which are 2 flat eights on top of each other.
A 6 stroke engine may be constructed by using a 2 cylinder 4 stroke which exhausts into a single cylinder with inlet valve opening at t.d.c. and exhaust valve opening at b.d.c. In effect a "compound" internal combustion engine.
Or it might be the Crower Six-Stroke - wherein water is injected into the combustion chamber at TDC of an additional cooling cycle, and that water flashing into steam provides a second power stroke. An ingenious idea, but with significant practical difficulties.
The volkswagen 1500cc engine shown is NOT the the 4 cam complicated engine they are talking about. It's a plain VW pushrod engine. The 4 cam is a much more elegant engineering masterpiece.
After the exhaust stroke water is injected. The heat in the cylinder turns the water into steam thus making a second power stroke. The 6th stroke is the exhaustion of the steam.
@@gabrielcoelho2346 Also clears all remaining combustion gasses from the cylinder and makes it run even cleaner than a 4 stroke ever can. I'm not sure why such an old idea hasn't be investigated further, I remember them talking about 50% efficiency with a petrol 6 stroke way back when most petrol engines had carburettors.
The Ariel square 4 was nicknamed the "Squariel", and considered advanced for it's time. Until the advent of Japanese machinery, it was highly desirable.

The gnome omega is not a rotary engine but rather a radial engine, which was a pretty common layout for early aircraft engines, although i doubt many examples survive today. For rotary examples see masda rx 7 or 8.
Patrick Taylor. It most certainly is a rotary engine. Rotary engine = engine block revolving around a stationary crankshaft. Radial engine = crankshaft rotating within a stationary engine block.
Upon further research i stand corrected, so apparently what we commonly call a rotary engine (the wankle engine) is actually a rotar engine?, something about a mistranslation or some such nonsense. Always have seen these types of engines refered to as radial engines, so my mistake.
The Gnome Rhone, though it is of radial configuration, is a true rotary engine. The pistons are not accelerated up and down in the bores as in a reciprocating engine since the crankshaft is stationary. The Porsche error is inexcusable.
The wankel IS NOT and was never a "rotary engine" (Wankel = KKM =in german KreisKolbenMotor= rotary piston engine... was only designed "Rotary" by Mazda because sound sexy...
The Commer Knocker is not supercharged in the conventional sense. All opposed piston 2strokes need a blower of sorts to scavenge the exhaust gases rather than to increase power by compressing inlet air. Another strange thing about the Jumo besides being an opposed piston motor is that it was a Diesel Aero engine. Not many of those around!
The blower on a 2 stroke Diesel is to blow air in to the combustion chamber as the engine cannot draw air in on it's own. Scavenging the exhaust gas is a useful byproduct. The big EMD 2 stroke diesels use both engine-driven blowers and turbochargers.
Commer knocker is not supercharged. Just because a motor has a Roots type blower on it doesn't mean it is supercharged ffs! It is blower scavenged. 2 stroke Diesels or Uniflow Diesels need a blower to aspirate them and scavenge exhaust from the cylinder since there's no dedicated exhaust and intake stroke. Stop promulgating ignorance. Do some bloody research before writing factual errors in vids dressed up as fact. End rant
The Commer TS3 'Knocker' is the same design as the Junkers Jumo 205 a more interesting example of an opposed piston 2 cycle diesel is the 'Napier Deltic.
The intake valve stays closed, the exhaust valve opens at BDC for an exhaust stroke of spent steam, and then at TDC the next gas intake stroke begins. So the succession of three revolutions and two power strokes is: 1st revolution: Gas intake, gas compression, ignition at TDC; => 2nd revolution: Gas power, gas exhaust, injection of distilled water at TDC; => 3rd revolution: Steam power, steam exhaust; (and repeat the whole thing) =>
So what do you call a Rootes blower if it's not a supercharger? Of course they're supercharged, it's the only way to make them run. The EMD 2-stroke diesels were the same, except they added turbochargers on some models as well as the superchargers for increased horsepower. A big 16V647 EMD engine could have 2 superchargers and 4 turbochargers. That's how they got 3000hp+ out of them. That's 16 cylinders, 647 cubic inches per cylinder.
I wouldn't call it a supercharger when it does not supercharge anything. Its purpose in this application is to get rid of exhaust gasses so I would probably call it a scavenger in this case. Not familiar with EMD engines. Were they opposed piston motors (2 pistons per cylinder) like the Commer knocker?
The supercharger used on 2-stroke diesels is not to scavenge exhaust gasses, it's to force air in to the combustion chambers, as 2-stroke diesels do not have an intake stroke, as 4-stroke motors do. You're obviously not familiar with 2-stroke diesels at all.
If it's the Bruce Crower six-stroke, it has an extra cycle after the power cycle in which an injector squirts distilled water into the cylinder at TDC. This flashes into steam, and provides an extra power stroke as well as cooling the engine. This essentially makes a second use of the fuel, and gets more power from the same amount of it. However, it needs another tank about the size of the fuel tank for the water, and obviously adds complexity.
What makes it an internal combustion steam engine, but do the valves stay closed during that steam cycle then? Otherwise it still will suck in fuel as the shown engine is a carburated one from a Honda Cub 50cc moped.
The intake valve stays closed, the exhaust valve opens at BDC for an exhaust stroke of spent steam, and then at TDC the next gas intake stroke begins. So the succession of three revolutions and two power strokes is: 1st revolution: Gas intake, gas compression, ignition at TDC; => 2nd revolution: Gas power, gas exhaust, injection of distilled water at TDC; => 3rd revolution: Steam power, steam exhaust; (and repeat the whole thing) =>
A clever guy in America has recreated an efficient 2 - stroke high - revving diesel engine that uses minimal parts , I think it has 3 vertical cylinders , 2 opposed pistons in each , supercharged , crankshafts top & bottom linked up by a heavy roller chain , I left him a message by e - mail to try to get a look at a Commer "Knocker" engine , as he , I believe , has modernised & re - created it . I knew a guy who drove one of these daily , in a car transporter , they always have their own note , you knew he was home 1/2 a mile away ! . The commer one used to wear out quickly , due to the complex oscillating linkages between the con - rods & the one central underslung crankshaft , these engines always sound as if they are screaming when you rev them , actually they aren,t turning over any faster than a 4 - stroke , just firing on every T.D.C. instead of every second one . Happy Spanners .
That engine is the Junkers Jumo, built in Germany for WWII, to power aircraft with diesel engines. Nothing new there at all.If you want to see something really strange, Google the Napier Deltic engine.
I read in a truck repair book about the Whitehorse , small mid engine air cooled have you ever come a cross one made in the early 1900 hundreds I think .
The Junkers engine at 2:55 was the basis on which the Comer knocker at 1:00 was built. Junkers were the pioneers. Great engineers. Horrid political and personal beliefs.
@@brucerogermorgan2388correct, yes, only it wasn't listed in the video, which is why i didn't reference it. Napier built Junkers engines under licence before the war, then used the knowledge to engineer the Deltic post war.
A 6-stroke engine was originally built to get around the Otto 4 stroke patents at the end of the 1800's.It introduced an extra cycle of intake and exhaust of fresh air - no fuel or ignition. As soon as the Otto patents expired it was dropped as it had no advantage over a 4 stroke.
Southdown Buses used Commer engines in some of their coaches. Noisy things they were too; being 2 strokes. I think they were made in 2 and 3 cylinder versions (operative words are 'I think'). The official designation is TS for Tilling Stevens...part of the Rootes Group but nothing to do with the scavenge blowers
Nope, only a 3 cylinder was made, never a 2 cylinder. Commer had plans to make a 4 cylinder TS4, but then Chrysler bought Commer and killed that project. The engine was originally built by Tilling Stevens, hence the TS3 designation, but Commer liked it and bought Tilling Stevens.
I suspect that some of those complex Porsche Fuhrmann engines were installed into Volkswagen Beetles by their owners to have a more powerful Volkswagen.
The Deltic design was based on 3 Napier Culverins joined together. The Culverin was a licensed version of the Jumo 204, which was a 6 cylinder opposed piston engine like the Jumo engine in the video. Junkers, who made the Jumo, were working on a 4 crankshaft diamond shaped version.
I bet the Commer Knocker is like a Detroit, and therefore not technically supercharged. The 'superchargers' on 2-stroke Detroits are really only superchargers when adapted for use on 4-stroke engines, as they aren't there to create 'boost'. They're scavenge pumps, since 2-stroke diesels can't suck air or get rid of their spent gases (and therefore can't run) under atmospheric pressure. Not being a knowitall, I just thought it was cool when I learned it and thought I'd share in case someone else might not know.
When you uploaded, you let youtube "fix" your video, didn't you... That's why your Gun Bus looks like the video is being stretched out like Silly Putty.
The SOHC Ford was not allowed by NASCAR, ruling that only pushrod engines would be allowed. This engine would have been a HUGE winner for Ford if it had been allowed to go into production, which was another reason why NASCAR would not allow it to compete as it was not a production engine. All of these rules are now no longer in effect. A lot of politics in NASCAR then, as well as now. Too bad. This is the kind of stuff that is killing NASCAR.
Those are flat engines you are describing, the pistons move away from each other towards a cylinder head and in their own cylinders. Opposed pistons move toward each other in the same cylinder, with no cylinder head and each piston is on its own crankshaft.
Yeah, wasn't that a 1600 Porsche 356 engine with canted exhaust valves (semi-hemi). So much easier to get more hp (than the Porsche) out of a VW engine with some aftermarket cylinder kits, stroker crank, cam, big valve and D port heads and still less expensive.
@ 4:50 that's a radial engine NOT a rotary ... rotary engine doesn't have pistons... A rotary engine does not have pistons but rather a triangular rotor that rotates around an output shaft. 6 stroke has a ua-cam.com/video/KkAD34nsTdk/v-deo.html
The first engine in this video was a dual port vw engine it has one cam with four loves on it not 4 cams and a monkey with boxing gloves on can set the timing in about 2 mins and if that same monkey was blind folded could put that engine together in about an hour and half
Thats supposed to be a Quad cam? I'm having SERIOUS doubts about that! Lol Edit: Another commenter correctly identified the Porsche eng as the 356C... which has ONE SINGLE Cam mounted in the case, below the crankshaft!
That doesn't look like a four cam Porsche to me. I had one. . I also had a 1500cc S engine that I could simply turn by hand at the pully at it always started. And I had a 1953 Porsche with a 1964 SC engine. And more.. So I doubt we see a four cam here!🤔🧐. Oh, four cams didn't use those carbs, the normal engines did
You're right, that was a pushrod engine there. It's for the Porsche 356A (1600), and those came with the Zenith carbs as seen on this one. The oil filter and the odd fuel pump location was a dead giveaway.😉👍
Biggest complaint about these videos is they give a name and some very minor details, but nothing else. Gimme something more than a blip saying it was weird...
It is in fact a Porsche engine but not a Carrera. You can tell by the shape of the valve covers and the fact that the generator mount on the top of the case is angled and not flat like a VW. The fuel pump bolts to the side of the case, all the VW engines that had fuel pumps bolted to the side of the case had the generator stands cast as part of the case (25 and 36hp cases).
That Lanz Buldog with it's Hot Bulb was incredible! Next to it the beautiful Square four - that was a fabled engine even when I was a kid. Aerial made some really advanced bikes and engines: water cooled, Shaft drive, belt driven all way ahead of the time. But for me the Lanz for the win.

The wankel IS NOT and was never a "rotary engine" (Wankel = KKM =in german KreisKolbenMotor= rotary piston engine... was only designed "Rotary" by Mazda because sound sexy...
So where is the Porsche 4 cam engine like in the picture of the video?
Der Jumo 205C bei 2:54 und der letzte Motor sind wohl die Besten.....
The Commer Knocker is not supercharged in the conventional sense.
All opposed piston 2strokes need a blower of sorts to scavenge the exhaust gases rather than to increase power by compressing inlet air.
Another strange thing about the Jumo besides being an opposed piston motor is that it was a Diesel Aero engine. Not many of those around!
The blower on a 2 stroke Diesel is to blow air in to the combustion chamber as the engine cannot draw air in on it's own. Scavenging the exhaust gas is a useful byproduct. The big EMD 2 stroke diesels use both engine-driven blowers and turbochargers.
FYI. The jumo 205c propeller is actually running backwards.
No mention of a Napier T9-29 engine? 18 pistons, 9 cylinders, 3 cranks, 1 super charger, 1 turbo charger and no valves or cylinderheads......
Yeah, I mentioned that. The Deltic was an amazing engine!
Walking threw the prop @4.00
Lanz Bulldog look great:)Plup,plup...
TonyValdez - Pre-start with a blow-torch to heat the head and then you get 30bhp @ 300rpm. Plup plup plup plup!
A bit more detail would be interesting - who made? when? etc....
Commer knocker is not supercharged. Just because a motor has a Roots type blower on it doesn't mean it is supercharged ffs!
It is blower scavenged. 2 stroke Diesels or Uniflow Diesels need a blower to aspirate them and scavenge exhaust from the cylinder since there's no dedicated exhaust and intake stroke.
Stop promulgating ignorance. Do some bloody research before writing factual errors in vids dressed up as fact.
End rant
The
Yes yes yes. See my above.

The Commer TS3 'Knocker' is the same design as the Junkers Jumo 205 a more interesting example of an opposed piston 2 cycle diesel is the 'Napier Deltic.
@@johndavidwolf4239 The Knocker used a single crankshaft with rockers whereas Jumo used 2 crankshafts
The little Ariel was cool
this 1st engine is a regular (normal) Porsche 356 engine ----no overhead cams
For first entry about the Porsche Fuhrmann engine you don't even show one, you just show the standard Push-rod Porsche engine.
VERY BAD VIDEO, MISINFORMATION FROM START TO END, BAD, BAD, BAD SHAME ON YOU CAR NEWS
The intake valve stays closed, the exhaust valve opens at BDC for an exhaust stroke of spent steam, and then at TDC the next gas intake stroke begins. So the succession of three revolutions and two power strokes is:
1st revolution: Gas intake, gas compression, ignition at TDC; =>
2nd revolution: Gas power, gas exhaust, injection of distilled water at TDC; =>
3rd revolution: Steam power, steam exhaust; (and repeat the whole thing) =>
The Commer engine was not supercharged.
Being an opposed piston motor it used a Roots blower to scavenge the exhaust fumes, not to increase power.
So what do you call a Rootes blower if it's not a supercharger? Of course they're supercharged, it's the only way to make them run. The EMD 2-stroke diesels were the same, except they added turbochargers on some models as well as the superchargers for increased horsepower. A big 16V647 EMD engine could have 2 superchargers and 4 turbochargers. That's how they got 3000hp+ out of them. That's 16 cylinders, 647 cubic inches per cylinder.
I wouldn't call it a supercharger when it does not supercharge anything.
Its purpose in this application is to get rid of exhaust gasses so I would probably call it a scavenger in this case.
Not familiar with EMD engines. Were they opposed piston motors (2 pistons per cylinder) like the Commer knocker?
The supercharger used on 2-stroke diesels is not to scavenge exhaust gasses, it's to force air in to the combustion chambers, as 2-stroke diesels do not have an intake stroke, as 4-stroke motors do. You're obviously not familiar with 2-stroke diesels at all.
You appear to be completely unfamiliar with opposed piston engines.
All 2-stroke diesels work the same way. whether they're opposed piston or not. Just go away, you have no idea what you're talking about.
does the ariel square four have the piston type dry sump oiling like triumphs, and when is it going to get oil on those rockers!
These all seemed like pretty normal engines.
6 stroke engine. Why?
If it's the Bruce Crower six-stroke, it has an extra cycle after the power cycle in which an injector squirts distilled water into the cylinder at TDC. This flashes into steam, and provides an extra power stroke as well as cooling the engine.
This essentially makes a second use of the fuel, and gets more power from the same amount of it. However, it needs another tank about the size of the fuel tank for the water, and obviously adds complexity.
What makes it an internal combustion steam engine, but do the valves stay closed during that steam cycle then? Otherwise it still will suck in fuel as the shown engine is a carburated one from a Honda Cub 50cc moped.
The intake valve stays closed, the exhaust valve opens at BDC for an exhaust stroke of spent steam, and then at TDC the next gas intake stroke begins. So the succession of three revolutions and two power strokes is:
1st revolution: Gas intake, gas compression, ignition at TDC; =>
2nd revolution: Gas power, gas exhaust, injection of distilled water at TDC; =>
3rd revolution: Steam power, steam exhaust; (and repeat the whole thing) =>
Thanks for that explanation, completely clear.
Baribrotzer Thanks!
A clever guy in America has recreated an efficient 2 - stroke high - revving diesel engine that uses minimal parts , I think it has 3 vertical cylinders , 2 opposed pistons in each , supercharged , crankshafts top & bottom linked up by a heavy roller chain , I left him a message by e - mail to try to get a look at a Commer "Knocker" engine , as he , I believe , has modernised & re - created it . I knew a guy who drove one of these daily , in a car transporter , they always have their own note , you knew he was home 1/2 a mile away ! . The commer one used to wear out quickly , due to the complex oscillating linkages between the con - rods & the one central underslung crankshaft , these engines always sound as if they are screaming when you rev them , actually they aren,t turning over any faster than a 4 - stroke , just firing on every T.D.C. instead of every second one . Happy Spanners .
That engine is the Junkers Jumo, built in Germany for WWII, to power aircraft with diesel engines. Nothing new there at all.If you want to see something really strange, Google the Napier Deltic engine.
I read in a truck repair book about the Whitehorse , small mid engine air cooled have you ever come a cross one made in the early 1900 hundreds I think .
6 stroke?! Phooey
Ariel S4 isn't strange, it did have cooling problems due to air flow over the heads of the 2 barrels at the rear,
The Junkers engine at 2:55 was the basis on which the Comer knocker at 1:00 was built. Junkers were the pioneers. Great engineers. Horrid political and personal beliefs.
pugmanick - The Commer was much better. It had only one crank, not two cranks & lots of gearing like the Junker Jumo.
Actually, the Jumo engine inspired the Napier Deltic long before the Commer TS3.
@@brucerogermorgan2388correct, yes, only it wasn't listed in the video, which is why i didn't reference it. Napier built Junkers engines under licence before the war, then used the knowledge to engineer the Deltic post war.
Explain something about the six stroke one(^^)
A 6-stroke engine was originally built to get around the Otto 4 stroke patents at the end of the 1800's.It introduced an extra cycle of intake and exhaust of fresh air - no fuel or ignition. As soon as the Otto patents expired it was dropped as it had no advantage over a 4 stroke.
The first one is a vw bug engine, how is it strange🤦
Who else thought the title said " strongest engines ever built"? 😂
Me
engine being run is not the ''complicated 4-cam Porsche version".
Where is the info on the six stroke engine?
Southdown Buses used Commer engines in some of their coaches. Noisy things they were too; being 2 strokes. I think they were made in 2 and 3 cylinder versions (operative words are 'I think'). The official designation is TS for Tilling Stevens...part of the Rootes Group but nothing to do with the scavenge blowers
Nope, only a 3 cylinder was made, never a 2 cylinder. Commer had plans to make a 4 cylinder TS4, but then Chrysler bought Commer and killed that project. The engine was originally built by Tilling Stevens, hence the TS3 designation, but Commer liked it and bought Tilling Stevens.
I suspect that some of those complex Porsche Fuhrmann engines were installed into Volkswagen Beetles by their owners to have a more powerful Volkswagen.
Napier Deltec engine...you forgot the most awesome motor
The Deltic design was based on 3 Napier Culverins joined together. The Culverin was a licensed version of the Jumo 204, which was a 6 cylinder opposed piston engine like the Jumo engine in the video. Junkers, who made the Jumo, were working on a 4 crankshaft diamond shaped version.
Scary, when I see stationary engine, non-shrouded propellers buzzing at speed.
Commer knocker sounds a lot like an 8v71 series
That is NOT a Fuhrman quadcam.
I think you got rotary confused with radial
I bet the Commer Knocker is like a Detroit, and therefore not technically supercharged. The 'superchargers' on 2-stroke Detroits are really only superchargers when adapted for use on 4-stroke engines, as they aren't there to create 'boost'. They're scavenge pumps, since 2-stroke diesels can't suck air or get rid of their spent gases (and therefore can't run) under atmospheric pressure. Not being a knowitall, I just thought it was cool when I learned it and thought I'd share in case someone else might not know.
When you uploaded, you let youtube "fix" your video, didn't you... That's why your Gun Bus looks like the video is being stretched out like Silly Putty.
The SOHC Ford was not allowed by NASCAR, ruling that only pushrod engines would be allowed. This engine would have been a HUGE winner for Ford if it
had been allowed to go into production, which was another reason why NASCAR would not allow it to compete as it was not a production engine.
All of these rules are now no longer in effect. A lot of politics in NASCAR then, as well as now. Too bad. This is the kind of stuff that is killing NASCAR.
Nothing strange about opposed piston engines, Subaru, Porsche still use then as BMW motor cycles....
Those are flat engines you are describing, the pistons move away from each other towards a cylinder head and in their own cylinders. Opposed pistons move toward each other in the same cylinder, with no cylinder head and each piston is on its own crankshaft.
Thats not a Porsche 4 cam!
The very first engine on here has the WRONG information. LOL
I guess it don't matter as long as you get views and ad clicks.
Yeah, wasn't that a 1600 Porsche 356 engine with canted exhaust valves (semi-hemi). So much easier to get more hp (than the Porsche) out of a VW engine with some aftermarket cylinder kits, stroker crank, cam, big valve and D port heads and still less expensive.
The flat Page dragline diesel engine should be on this list.
Interesting subject but hard to watch due to the camera rarely being still.
Horizontally opposed engines, the piston crown faces opposite of each other.
The commer knocker if known as a commer ts3
They made a beautiful sound flat out pulling a truck up hill
also a junkers engine from memory.
Much like the Jumo aircraft engine , but usable in vehicles .
FYI ft/lb and lb/ft are NOT the same measure...for torque its lbs/foot...not the other way around
No replacement for displacement
Have to appreciate simplicity of Gnome air cooling. Unique but none really strange though, like Atkinson Cycle odd. Gunbus just a big V twin.
1:48 Six Stroke ??
What’s up with that. Tell me more. Looks like a Honda trail 90
What"s strange about a flat 4? VWs had them, same basic engine.
It was on the list, that's what's strange about.
@ 4:50 that's a radial engine NOT a rotary ... rotary engine doesn't have pistons... A rotary engine does not have pistons but rather a triangular rotor that rotates around an output shaft.
6 stroke has a ua-cam.com/video/KkAD34nsTdk/v-deo.html
The first engine in this video was a dual port vw engine it has one cam with four loves on it not 4 cams and a monkey with boxing gloves on can set the timing in about 2 mins and if that same monkey was blind folded could put that engine together in about an hour and half
Thats supposed to be a Quad cam? I'm having SERIOUS doubts about that! Lol
Edit: Another commenter correctly identified the Porsche eng as the 356C... which has ONE SINGLE Cam mounted in the case, below the crankshaft!
Fairbanks-morse produce a vertically opposed 6 cylinder diesel.
Patrick Bass - Fairbanks-Morse had the German engines beat long before the Junkers.
That wasn't a Furhman engine!
That doesn't look like a four cam Porsche to me. I had one. . I also had a 1500cc S engine that I could simply turn by hand at the pully at it always started. And I had a 1953 Porsche with a 1964 SC engine. And more.. So I doubt we see a four cam here!🤔🧐. Oh, four cams didn't use those carbs, the normal engines did
You're right, that was a pushrod engine there. It's for the Porsche 356A (1600), and those came with the Zenith carbs as seen on this one. The oil filter and the odd fuel pump location was a dead giveaway.😉👍
I think there was too much far away overview scenes and way too little detail close-ups in this video...
Biggest complaint about these videos is they give a name and some very minor details, but nothing else. Gimme something more than a blip saying it was weird...
Are there any Diesel Wankel rotary engines (maybe with turbos)?
Nope, can't get the compression pressures high enough on a Wankel to make it a Compression Ignition engine.
That VW engine you say is a 547 is not, you have a basic VW engine. The 547 has 4 cams and huge heads
It is in fact a Porsche engine but not a Carrera. You can tell by the shape of the valve covers and the fact that the generator mount on the top of the case is angled and not flat like a VW. The fuel pump bolts to the side of the case, all the VW engines that had fuel pumps bolted to the side of the case had the generator stands cast as part of the case (25 and 36hp cases).
you forgot the triflux nearly 1000 hp per litre..
I gave my wife a six stroke once but I apologized for three!
I'm down to one stroke!
I gave her 7
the porsh is a 4 boxer not a 4 flat neither was the vw 1500s a 4 flat it was a boxer
Same thing
Not a classic engine but should of added the achates 3 cylinder opposed engine.
I don't know, I don't trust that company yet, since they have not yet released a working product.
Still trying to figure out what's strange about a Porsche/VW motor?
