Wankel Engine

    The Wankel #engine is a type of internal #combustion engine using an eccentric rotary design to convert #pressure into rotating motion.

    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 ;

    It produces three power pulses every crank shaft cycle compared to one pulse per cycle in two stroke engine and one pulse per tow cycles in 4 stroke engine

    #Wankel engine disadvantages :

    Low Thermal Efficiency

    Due to the long and uniquely-shaped combustion chamber, thermal efficiency of the engine was relatively lower compared to piston-cylinder counterparts. This also often led to unburnt fuel leaving the exhaust

    Oil burning :

    By design wankel-engine burns oil because there is an injector squirts oil in the intake tube to lubricate the rotor so the oil reaches combustion chamber and  burns

    Rotor Sealing : 

    It’s challenging to seal the rotor when it’s surrounded by vastly different temperatures

    It used in automobiles, motorcycles, racing cars, aircraft, go-karts, jet skis, snowmobiles, chainsaws, and auxiliary power units
