Scuderi engine

Has anyone seen this? I wonder if it can actually run well.

That's an interesting design.

So.. functionally. It's a 2 cylinder, but it has to move around 4 pistons. Doesn't seem very efficient to me. But, I'm far from an engineer.

I was thinking that too but.... Because the intake piston is pushing air into the combustion/ exhaust chamber which fires AFTER top.dead.center, the power stroke will last longer so even if it isn't as efficient as a conventional engine that extra length of the power stroke will outweigh the extra resistance? It is supposed to produce more power and less emissions but i still need to see it run under load before i believe it. Apparently Daimler and Honda are already involved and they will be putting them in cars next year.

Like most things mechanical - there's no "free lunch" - but this little engine is pretty darn kool... and like a 'blown engine' while the blower takes a bunch of HP to make the power - the power made far exceeds the amount used. Now if they could just fix that exhaust note...

Because the cycle is split, you get one power stroke for every crankshaft revolution, instead of every other -- that's part of the efficiency increase. Also, the high pressure air aids the combustion process, which minimizes pollutants and likely soot as well for the diesel version. Super-cool, highly intuitive, simple yet very elegant in my book!
