The expansion and contraction draws air and fuel into the engine, compresses it and makes power as the gasses expand and then expels the exhaust. ... It is smooth, and has and extended power stroke. ... Firing Cycle (the cycle goes on in all three chamber simultaneously) INTAKE COMPRESSION POWER EXHAUST ...
Most rotary engines use only two rotors to generate power, which allows them to be smaller engines with less moving parts; lasting longer and remaining more efficient. ... Because of the low rotor to engine speed ratio, the rotary engine can withstand driving under higher load and at higher RPM's thus having high top speed, and incredible horse power as well as overall power in the higher rpm's. ... The simplicity of design and smaller size of the Wankel engine allows for lower production costs compared to piston engines of similar power output. ... Also, due to a 50% longer stroke...
