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.
When I saw the first engine, I thought: isn't it the most simple engine ever?

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,
These all seemed like pretty normal engines.
A bit light on for detail. The Gunbus looked to be 2 cylinders from a Pratt and Whitney radial engine but no explanation was given.
6 stroke?! Phooey
That first engine is not the Fuhrmann Porsche. It's just a garden variety early Porsche, which is a souped-up VW motor.
So where is the Porsche 4 cam engine like in the picture of the video?
The Commer Knocker is the only engine I have heard that sounds like a Detroit.
Much like the Jumo aircraft engine , but usable in vehicles .
engine being run is not the ''complicated 4-cam Porsche version".
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 .
Walking threw the prop @4.00
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.
The first one is a vw bug engine, how is it strange🤦
Der Jumo 205C bei 2:54 und der letzte Motor sind wohl die Besten.....
Are there any Diesel Wankel rotary engines (maybe with turbos)?
What"s strange about a flat 4? VWs had them, same basic engine.
It was on the list, that's what's strange about.
An 8 litre engine producing 50 Hp... SMH
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.
Leave it to the french to make 50hp from 8 litres.
Though to be fair the design was pre-WWI
The Porsche engine , unnecessarily complicated, over engineered, as with their bathtub engines
1:48 Six Stroke ??
What’s up with that. Tell me more. Looks like a Honda trail 90
Opel cih engine is Miss
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.
that Porsche engine you show here is the 356a motor yes a 1300 or a 1600 i have worked on early Porsches most of my life and yes the quad cam engines were complicated but in a 1955 spyder they were capable of 165mph not bad for a 1955 model car and to say they are a tweaked VW motor you know absolutely nothing about them whatsoever my dear friend
Nothing even slightly strange about a VW- based flat 4. Didn't watch further
This video should be retitled "Unusual successful engines". There is nothing strange about a modified VW engine, built in large numbers. There is nothing strange about the Lanz Bulldog - hot bulb semi-diesel engines were once very common, from various manufacturers.
The video refers to the Commer Knocker as supercharged - this is an incorrect use of the term. 2-stroke engines, unless loop-scavenged like a lawnmower or whipper-snipper (which are VERY fuel inefficient and burn oil), cannot suck in air. Therefore the air has to be driven in by a fan or air pump. Supercharging is the forcing in of air at above atmospheric pressure, which may or may not apply to 2-stroke engines.
A really strange engine is the Sarich orbital engine - in fact it is so strange, completely stupid actually, it exists only as a museum exhibit, badly worn after just 10 minutes or so operation.
Your title is a joke,,not one strange engine,,,,,,6 stroke?? Happy hour??
number 1 is just a vw aircooled engine with doublé carburetor.
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!
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.
Two cylinders, not two-stroke. I believe the cylinders are from a WWII radial aircraft engine, but I'm not sure which one.
"Strangest Engines Ever Built" and the first video is a Type I VW; one of the most common engines ever built.
Yeah, a 36hp with Porsche heads.
@@unosuave I don't even think they are Porsche heads. Dual carb setup is the only non stock thing I see about that engine.
@@gregorytimmons4777 you need to take another look far from a beetle engine
@@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 first video is a '55-'56 356 Porsche engine.
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.

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.
Shane Norman Yup! It's the Porsche 356C eng... single cam mounted directly below the crank.
Yes, there's no twin camshafts under those valve covers!
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.
@@geoh7777 ITS A 4 cam engine , the cams are inside the block thus pushrods, thats why it took 8 hours to tune.
Nice video... just sometimes move the camera away so we can see the whole motor... not just bits.
The Furhman 4 cam Engine is one hell of a piece machinery.
But the one in the Video is a standard 356 one...
The Comma looks like it needs a pressure-washer as an accessory!
The porsche engine in the video is a normal 356 engine, is pretty common, like the vw one. The carrera engine is the one that is rare
Alberto Ruiz early vw engine s we're copied by Porsche
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.
Dr. Porsche designed the VW beetle, and it's engine, you fucking moron.
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.

I love that comer knocker motor, just seems so smooth : )
Doug Harvey I believe they first built for trains
The Commer Knocker revved up sounds like a 2 stroke Detroit Diesel.
That first strange engine is a plain old VW with dual carbs.Looks like the one in my 67 Beetle.
The porsche engine in the video is a normal 356 engine, is pretty common, like the vw one. The carrera engine is the one that is rare
A bit more detail would be interesting - who made? when? etc....
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!
Bruce
All that we don't know or understand is "strange" to us.
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.
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.
called in at Vale Onslow in sparkhill back in around 1998 got chatting to an old er guy he took us into the workshop and showed us some Square fours he was building from a colllection of spares he had bought from the factory .Turned out it was Vale Onslow himself realy nice chap
Could he have bought the parts from the Healey Brothers? They built Ariels up until the late seventies, in Redditch. They also performed powder coating there, and I had my Suzuki frame done by them.@@nickbadi3599
@@robertlawson8572 It was about 17 years ago now im certain he said he had bought the factory clearance stock
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!
0:55 beautiful engine.
Who else thought the title said " strongest engines ever built"? 😂
Me
The little Ariel was cool
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.
Sterling Crockett
Thanks for the info ! I always wondered about how the aircraft flew straight considering the engine would act like a huge gyroscope
I wonder how they kept any oil in the crankcase. Looks like it would immediately get slung into the rocker covers.
They used a total loose type of oiling They really never stayed up long enough to run out of oil
For first entry about the Porsche Fuhrmann engine you don't even show one, you just show the standard Push-rod Porsche engine.
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......
SOHC Ford isn't that strange, just ahead of its time. These others are flat out strange for sure.
Maybe ahead for its time in America... Still cool and interesting
Ben Hop
Definitely cool and interesting no matter where you are. But not strange.
upside downdog 4.6 4.8 v 6 and v8 modular ford have been used in light trucks and mustangs sence the late 90s
The 5.0 cobra mustange from the late 90s is a dohc v8. Small 289 ci engine working VE. A 2.2 l H22 still makes more hp per
Shoc engines ... gotta love auto correct and the internet
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!
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!
that first engine isn't the quad cam engine it's single cam/ohv porsche engine.
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.
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 commer knocker seems very smooth running for a two stroke diesel
Very smooth
Makes sense! Every stroke would have two pistons counterbalancing one another!
Commer knocker sounds a lot like an 8v71 series
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.
Ariel S4 isn't strange, it did have cooling problems due to air flow over the heads of the 2 barrels at the rear,
I suspect that some of those complex Porsche Fuhrmann engines were installed into Volkswagen Beetles by their owners to have a more powerful Volkswagen.
That 356 engine is not a 4 cam Ernst Fuhrmann type engine, it’s a normal pushrod one
No replacement for displacement
you forgot the triflux nearly 1000 hp per litre..
Have to appreciate simplicity of Gnome air cooling. Unique but none really strange though, like Atkinson Cycle odd. Gunbus just a big V twin.
FYI. The jumo 205c propeller is actually running backwards.
Scary, when I see stationary engine, non-shrouded propellers buzzing at speed.
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.
supercharger = blower
Benjamin Esposti Yes Blower and supercharger is the same thing but if its a blower or a supercharger depends on what form of engine its mounted on
Commer knockers are BOTH... In some cases. Usually scavenge charged to increase power... Always liked the unique sound.
@@BenjaminEsposti no it doesn't!
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.
The flat Page dragline diesel engine should be on this list.
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
you forgot the Napier Deltic engine
Neale Frazer - The Deltic was an amazing engine used for British Rail. Smooth running but very complex. Hard to start cold.
You would not explain thr 6 stroke engine?? Are you kidding?? Sometimes I'm really wondering what's up with this channel...
CapriceDriver89 this channel has a stupid admin
yeah wtf is a 6 stroke.
Suck, Squeeze, Bang, Blow, Cuddle, Uber
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.
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.
Glad someone was able to 'splain that! Thanx!😊
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.
this 1st engine is a regular (normal) Porsche 356 engine ----no overhead cams
Horizontally opposed engines, the piston crown faces opposite of each other.
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.
Fairbanks-morse produce a vertically opposed 6 cylinder diesel.
Patrick Bass - Fairbanks-Morse had the German engines beat long before the Junkers.
I WANTED TO SEE THE THUMBNAIL ENGINE
I think you got rotary confused with radial
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) =>
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.
Interesting subject but hard to watch due to the camera rarely being still.
Where is the info on the six stroke engine?
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!
Looks like a duel carb vw or porsh maby a mix of parts hard to say
fucken killer jason 1600 cc Porsche 356 motor, early 60s...
To me looks like a dul carb vw cosidering the valve covers and the size also the carbs also says vw in the vid
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!
Que motor es el segundo que muestran está muy estraño no lo avía visto de qué lugar de origen sera
Still trying to figure out what's strange about a Porsche/VW motor?
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.
(s)Navy Engineman
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 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...
FYI ft/lb and lb/ft are NOT the same measure...for torque its lbs/foot...not the other way around
That wasn't a Furhman engine!
That is NOT a Fuhrman quadcam.
Gunbus the largest motorcycle engine?
Nope, the Flying Millyard is bigger, 5.0 Vtwin. Really loud when you're next to it.
Boss Hoss uses up to 502 Chevies that I know of? The Flying Millyard would be about 300 cubes at 5,0, and the Gunbus would be much bigger than that at 410.
I gave my wife a six stroke once but I apologized for three!
I'm down to one stroke!
I gave her 7
