Multiple-displacement engine

摘要

A multiple-displacement engine which can be operated either in a full-displacement state in which all the cylinders are operative or a part-displacement state in which a part of the cylinders are inoperative is provided with a balancer for attenuating torque fluctuation due to explosion in the operative cylinders in the part-displacement state of the engine. The engine is further provided with a balancer actuator which actuates the balancer when the engine is operated in the part-displacement state.
