STRANGEST V8 Engine Ever Made

Dieter Hartmann-Wirthwein patented a system in which four cylinders operate using only one single connecting rod. This allows all four pistons to work as a single mechanical assembly, which transmits power to the crankshaft via a single connecting rod on a single crankpin

The outside pistons don't contribute to power

[@WindyCityJumpman]

It appears that the energy of the power stoke from the outer two pistons only contributes to the compression stoke of the inner two pistons and not to the crankshaft power. This means that the engine performance is essentially the same as a basic 4 cylinder, but with the compilation of added mass, friction and components. Looks neat, but I don't see any benefit

[@isekawai]

exactly what i was thinking. The 4 side pistons only work to accelerate the middle pistons and the fireing order has to be a nightmare

Exactly what I was thinking but the outer two pistons are contributing to engine power by providing upward torque to the crank. Instead of the compression stroke being a parasitic drag it contributes torque. Kinda like a two stroke engine.

And incredibly quiet for basically having no muffler.

Some horsepower and nearly 0 torque, such is the way with a high response short stroke engine.

[@Petrolhead99999]

52 cid and 70hp... And naturally aspirated. That's really excellent specific output. For reference, the F20C from the S2000 makes 240 from 120 cid, and that's basically the best anyone has ever done with an N/A engine. He's solved the bore/stroke ratio problem, which basically puts an upper bound on stroke because of excessive connecting rod angle. If the angle is too high, you hit the bottom of the cylinder.

will this withstand at High rpm?

[@LBCB94025]

can you give the stats on the difference between this and a regular V8 of the same size???? was it an improvement????

[@ValentineC137]

No improvement, at best it’s identical but built using a more complex setup

[@gabrielsansar6187]

that`s the most beautiful thing i`ve seen this year

[@jaimearayacabrera374]

Puede tener 1,2,3 o 4 bielas pero no deja de ser un V8 plano común, si la idea es quitar piezas de fricción y peso es buena opción, pero sigue teniendo el problema de volumen y espacio en bahía de motor, siempre he pensado que el WANKEL, RWNESIA O ROTATIVO son la mejor opción en cuanto a espacio aunque tiene más defectos que el tradicional de pistones alternativos. PD: amo los V8 puros y brutos de vieja escuela.

What a crazy sound!!! I love it ❗❗❗❤️

The amount of straight force on that one piston arm is crazy bro

That'll be some very aggressive compressionstroke

[@matthew6202]

That must be one strong rod.

[@gagepuffinbarger6939]

That poor crank

[@alienclay2]

Not necessarily, In a regular 4 stroke the rod only sees combustion pressure once every 4 strokes, the rod in this engine sees pressure (push and pull) every stroke but the peak should be the same. the usual point of failure in a 4 stroke is the wrist pin at TDC at high RPM at the end of the exhaust stroke because of initial forces of the piston and the open valves keeping the air cushion from pushing back. in this engine, there is a push back on the ...pins?....after every stroke so I would assume the pressure on them collectively would be less or the same.

Now thats a real V8 engine

[@horowizard]

I would think those piston rods would wear out and even break rather quickly.

[@kevinroberts781]

Why would you think that? It's the exact same force as any engine if you think about it

[@horowizard]

@@kevinroberts781 Twice the stress.

[@kevinroberts781]

@@horowizard Only on start up and that's easy to design for. Once the engine is rotating it's basically the same stress.

[@ValentineC137]

@@kevinroberts781 The piston rod is under the stress of 4 pistons instead of one, aswell as that force constantly switching between compression and tension.

[@DavidDenmark]

I don't see this combo making serious horse power ! Short track? Power will be made down low in a low power band due to short stroke.😊
