How Does Wankel Engine Works?

The first Wankel engine was first developed by a German engineer  named Felix Wankel in 1929. Now the Modern Engine was addpoted designed by Hanns Dieter Paschke.

Wankel engine is an Internal combustion engine which is different from the piston cylinder arrangement .The Wankel engine is a type of internal combustion engine using an eccentric rotary design to convert pressure into a rotating motion instead of using reciprocating pistons .In a piston engine,four-stroke cycle intake, compression, combustion and exhaust takes place in the same volume of space (the cylinder) .Where as in case of Wankel Engine it was a completely different way than the conventional piston engine.In Wankel Engine four-stroke cycle takes place in a space between the inside of an oval- like epitrochoid shaped housing and a rotor that is similar in shape to Reuleaux triangle but with sides that are somewhat flatter. The very compact Wankel engine delivers smooth high- rpm power. It is commonly called a rotary engine , though this name applies also to other completely different designs.




In piston engine, the rotary engine uses the pressure created  when a combination of air and fuel is burned. When the Fuel Burned the high temperature and  pressure gases are produce and these pressure is contained in the cylinders and forces pistons to move back and forth. Then the piston which are moving back and forth are transmit the power to connecting rods and crankshaft which convert the reciprocating motion of the pistons into rotational motion that can be used to power a car.

Where as in case of  rotary engine, instead of pistons the pressure of combustion is contained in a chamber formed by part of the housing and sealed in by one face of the triangular rotor  incorporating a central ring gear is driven around a fixed pinion within an oblong chamber.The rotor has three convex faces which acts like a piston.

The rotary motion is transferred to the drive shaft by an eccentric wheel that rides in a matching bearing in the rotor. The drive shaft rotates once during every power stroke instead of twice as in the Otto cycle.
