Wankel rotary engine and its working principle explained!

Wankel rotary engineWankel rotary engine also known as a Wankel engine or a rotary engine was developed by Felix Wankel in the 1950s. The Wankel rotary engine is an internal combustion engine that uses the same principle of converting pressure into a rotating motion. However, this engine does it without the mechanical stress and vibrations at high rotational speeds of the piston engine.

Felix Wankel and his colleagues managed to establish the housing design of the engine by following several steps. First, they fixed and outer-toothed gear on a white sheet. Then, they interlocked it with a bigger inner-toothed gear.  They did this with a ratio of 2:3 between the two gear. Next, they attached an arm on the outside of the bigger inner-toothed gear with a pen.  The pen generated a cocoon-shaped trochoid curve when they turned the inner-toothed gear on the small gear.
