The Mazda Wankel rotary engine completes all stages of internal combustion just like a standard piston engine but with a different angle. Instead of pistons, the Wankel engine uses triangular-shaped rotors mounted onto an eccentric shaft and unlike the piston engine where air is compressed in cylinders, it has a rotor housing instead.
At the start of the cycle, the rotor creates a void that allows air and fuel mixture into the housing, this mixture is then compressed before being ignited by two spark plugs at the combustion phase. The explosion causes the rotor to move due to the expansion of the chamber and at the end of the cycle, exhaust gases are squeezed out of the housing and the cycle repeats.
A simple four-stroke piston engine has at least 40 moving parts, from pistons, connecting rods, and valves to timing gears and the crankshaft. Unlike the piston engine, the rotary engine significantly reduces the number of moving parts, with a single-rotor rotary engine consisting only of two moving parts, the rotor and eccentric shaft. The number of moving parts only rises with the addition of rotors, for example, a two-rotor rotary engine would comprise of three moving parts only, the two rotors and the eccentric shaft.
