Duke engine (rotary type but with pistons!)

Pretty cool.

That's pretty wild, I'm not going to lie - I've always been a fan of the Wankel engine from a geek/nerd standpoint, but I don't have any ownership experience with how reliable or easy to maintain they actually are.

This thing looks like a nightmare in terms of bearings and precision components for getting the balance correct across the axis, but there's /plenty/ more things that people have engineered with similar issues, lol.

I'd love to drive something that had this in it - one day


Thanks for sharing!

Nothing new here.  Just putting combustion in a wobble-plate motor to make it an engine.  Hydraulic motors have run on this for a long time.  Hell, there are stroke-adjustable wobble-plate engines out there too!

I'm not impressed with the pistons rotating though... thats a lot of rotating mass.

interesting, similar design to many a/c compressors for cars

check out the mighty yet tiny engine
