New Engine Design

Reminds me of a Wankel. Pretty cool.

That engine scares me, looks like it will wobble apart.

Yeah, very cool idea, but seems like with more complex motion there is more of a scare of engine life. Interesting none the less.

The pistons have the same motion as any other engine, but the crank is different. The petal style crank makes it compact and while it looks to be more complicated it actually has less parts. Less weight as well.

To a degree this is correct, but you have to remember that the actual element the pistons sit inside also has to spin. which creates an entirely new wear area not common to other engines.

The idea is ingenious, and solves a great deal of problems with other engine designs. The concern is that it likely also creates a whole new world of problems.

Wait hold on, I am incorrect, quickly just watched the video again. So each piston sits inside its own machined sleeve. Not in one large rotating chamber. That makes more sense, but also brings up a larger concern for tolerances as the engine wears.

If that "petal" wears unevenly or develops any sort of play, then your engine is going to run weird, and could lead to catastrophic failure.

I don't know, I'm sure there is a way to make it work, and I am sure they will find it, but will it be as revolutionary as they make it seem? No idea.

It is cool to see that there is new stuff like this still being developed for combustion engines.
