I've recently found out about a Wankel Engine, much more sensible engine design then the usual engines we are used to. This is something most people are unaware of.Most of us are used to common 4-stroke cylinder engines found in most today's cars. One such engine consists of a cylinder body, piston that moves up and down, and a connecting rod that connects the piston with the crankshaft, turning linear movement into a rotational.
