What is a Wankle (rotary) engine?

Read this,it's far easier than me trying to explain it.

It's an engine where the pistons, cylinders and crank are replaced by a rotor spinning in a special shaped chamber. Very smooth running and revs to high speeds. Also high oil and fuel consumption, and self destructs if revved just a bit too far

It sounds like that could be a powerful concept, the wankel has plenty going for it. It desires a jet unit this is optimized for bigger rpm and those are used on issues like Yamaha jetboats. those engines rev severe, not 40000 rpm yet perhaps 10-12k rpm could be ok for the jet unit.. you may might desire to marinize the engine yet i think of it would desire to be accomplished. not saying it may be!

Try Googling NSU RO80. A very advanced car for its time.

This would take too long.

Google it: Mazda Wankel engine wiki

its a toy that burns a lot of petrol and wears out rotor tips for bloody fun

There is a great little animation about 1/3 way down that page... Note when the spark plugs fire...
