Strangest Engines Ever Built

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?

"I see angels on Ariels in leather and chrome swoopin' down from heaven to carry me home."

At 3.30: we love carbonmonoxide poisening.....we love the smell of exhaust gasses....

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.
