Rotary

Also known as the wankle engine this engine is very different from the others out in production today.  This engine is souly based on rotational motion and is a lot more complex in construction.  This format of engine uses the same steps for powerful output such as any other engine today.  It uses intake, compression, ignition, and release of exhaust.  The wankle engine uses these for steps in a different and more fluent motion. 

There are no cylinders, instead there are compression chambers.  Within these chambers there are triangular rotars that spin in a circular motion within the chambers.  As the triangular rotars turn within the chambers they create three seperate air pockets each, doing an imporatnt job.  The air pockets created are creating the four steps (intake, compression, ignition, and the exiting of exhaust). 

The three pockets are creting the four steps all at once.  As the rotar is turning it is letting in a fuel/air mixture, compressing, and igniting.  In a way it is the same idea as a two stroke engine.  Abnother feature that makes the rotary engine like a two stroke format is because it is not a clean burning engine.  Unlike the four stroke much fuel in the rotary process escapes out the tailpipe.
