Abstract

An actuator of a rotary engine that can realize different compression ratios includes three parts: an eccentric shaft, a triangle rotor and a control system. The eccentric shaft includes the front part of the eccentric shaft, the combination of an electric three-jaw and the rear part of the eccentric shaft. The triangle rotor includes the variable volume actuator, the front part of the rotor and the rear part of the rotor. The control system controls expansion and contraction of the electric three-jaw. The eccentric shaft part passes through the triangle rotor part to make the combination of electric three jaw to arrange in the annular groove. The reciprocating motion of the variable volume actuator is controlled by the expansion and contraction of the claw top of the electric three-jaw. Engine compression ratio may therefore be adjusted using the compression ratio adjustment system.
