4 strokes of the combustion cycle in a single crankshaft revolution

Is it noisy? It looks like the roller bearing on the intake/exhaust piston drive cam will have to lift off that cam and land on it with every revolution.

It's neat, but I don't see the benefit. It's like an approximation of the Atkinson cycle with full stroke expansion and a reduced volume intake stroke, but with tons more parts and with a really unreliable looking engagement/disengagement of the two pistons. Also tons more rotating mass. And lots of weird new harmonic balancing issues. Why do this over Atkinson?

If you look closely it has 3 conrods and the wrist pins are only held on one side with the smaller conrod cutting through the middle. Also, the small wrist pin would have to be very small. I would say it would not run for very long if at all.

......Why?

so whats pulling it down for the intake stroke?? more useless stuff.

[marksbug]

dont a 2 stroke already do this....with much less complicated parts.

it's a time machine....wasted time finding ways to waste time while wasting time, perhaps they should put some watch hands on it so it could count all the wasted time....just messing as this type of time isant wasted as it may just turn into something someday or spawn a bright idea while somebody is wasting time looking at it. and thats what this forum is awesome for, spawning new ideas and expanding on the ones you or somebody else has/had/will have. like the girls of tick tok...hmm that gives me an idea!!!! and just when you thing you've seen it all...hear comes marksbug.
