In contrast to the more common reciprocating piston designs, the Wankel engine delivers advantages of simplicity, smoothness, compactness, high revolutions per minute, and a high power-to-weight ratio. This is primarily because there are three power pulses per rotor revolution. In a two-stroke piston engine there is one power pulse per crankshaft revolution, with one in two revolutions in a four-stroke piston engine. Although at the actual output shaft of a rotary engine, there is only one power pulse per revolution, since the output shaft spins three times as fast as the actual rotor, as can be seen in the animation below, it makes it roughly equivalent to a two-stroke piston engine of the same displacement. This is also why the displacement only measures one face of the rotor, since only one face is working for each output shaft revolution. • The engine is commonly referred to as a rotary engine, although this name also applies to other completely different designs, primarily aircraft engines with their cylinders arranged in a circular fashion around the crankshaft. The four-stage cycle of intake, compression, ignition, and exhaust occur each revolution at each of the three rotor tips moving inside the oval-like epitrochoid-shaped housing, enabling the three power pulses per rotor revolution. The rotor is similar in shape to a Reuleaux triangle with the sides somewhat flatter. • Concept and design • The design was conceived by German engineer Felix Wankel. Wankel received his first patent for the engine in 1929. He began development in the early 1950s at NSU, completing a working prototype in 1957.[1] NSU subsequently licensed the design to companies around the world, who have continually added improvements. The engines produced are of spark ignition, with compression ignition engines having only been built in research projects. • The Wankel engine has the advantages of compact design and low weight over the most commonly used internal combustion engine employing reciprocating pistons. These advantages have given rotary engine applications in a variety of vehicles and devices, including: automobiles, motorcycles, racing cars, aircraft, go-karts, jet skis, snowmobiles, chainsaws, and auxiliary power units. The power-to-weight ratio has reached over one horsepower per pound in certain engines. • Tags: • rotary engine,wankel engine,rotary engine cars,rotary engine vs piston engine,rotary engine sound,rotary engine mechanism,rotary engine mechanism animation,rotary engine animation,wankel engine animation,wankel engine working,wankel engine motorcycle,wankel engine in aircraft,rotary engine in aircraft,rotary engine in car,rotary engine working principle,wankel rotary engine working,how rotary engine works,rotary,mazda • rotary engine,wankel engine,rotary engine cars,rotary engine vs piston engine,rotary engine sound,rotary engine mechanism,rotary engine mechanism animation,rotary engine animation,wankel engine animation,wankel engine working,wankel engine motorcycle,wankel engine in aircraft,rotary engine in aircraft,rotary engine in car,rotary engine working principle,wankel rotary engine working,how rotary engine works,rotary,mazda • #EngineeringStudyMaterials
