Question

Quizplus · Accepted Answer

A rotary engine operates using a rotor that spins within a housing, and uses ports in the housing to intake and exhaust air/fuel mixture. The engine also requires spark plugs to ignite the fuel, and a crankshaft to transfer energy to the transmission. However, the use of poppet valves, which are commonly found in traditional piston engines, is unlikely in a rotary engine.
