Re: ROTARY VS PISTON WHAT DO YOU THINK?

I read a great book about the history of the Wankle a while back, I wish I remembered the name of it. It actually started out as a water pump. Makes sense, after all engines are just air compressors at the end of the day. That said the biggest problem was the engineering issues of the apex seals. Mazda managed to figure that out but the issue now is combustion temperatures which bring NOx emissions way up. This is the reason they don’t make them anymore. It’s a great concept but it does have some issues and limitations that hold it back from getting any bigger.
