"It enables the production of a 65 HP engine weighing about 90 lbs with 300 ft-lb torque operating essentially vibration free at 1800 RPM."

 

200 HP @ 2000 RPM
650 ft-lb torque @ 1200 RPM
265 lb dry weight

Wow!

 

damn, you beat me to it! LOL that is amazing! the next generation of combustion engines....thats some star trek ish!

 

It's pretty simple actually. Think of your standard engine, piston attached to a crank shaft by rods. Each is off set of center on the crank shaft. When a cylinder fires this axial movement causes radial movement one the crank. Got it? Ok. In this case the pistons run parallel to the output shaft. Each set of pistons 6 in total are attached. At the center of each piston set there is a roller bearing on the end each piston. In the center is the cam. Don't think of it as a traditional cam. See how it has a wavy look. As the piston fires it forces axial force on the center cam this is also the exhaust stroke for the opposite attached cylinder. As the force is applied to the top of the center cam radial force is transmitted to the output shaft. Does that make sense?

 

Very efficient, very simple....wonder why it hasn't been done before?

 

wtf is it

 

Will it bolt up to a subaru tranny?

 

OK let me try... The things marked "piston" go back and forth so that the wobbly ring thing spins thus spinning the middle part or crankshaft. Voila.

 

Actually, I have been looking at the sketch - I think there are several places for failure, or at least weakness....have they actually built one of these or is it just a concept?

I suspect it is just a concept because there are only sketches and no pics and the numbers are way to round - 200 and 650 to be actual measurements.

It is a good idea, a really good idea, but I don't think it has been built yet.

 

IF they can nail down reliability and emissions, they will be on to something nice.

 

Hmm... sounds like it would be a real pain to change the spark plugs on the output side.

Can someone explain this to me:
I don't get it ...? If there are bearings on the conrods that "ride" on the sinusoidal cam, then there IS side loading on the pistons because the force will be normal to the contact point on the cam. Am I missing something?
