    • A method and apparatus for compensating for increased engine idle speed upon breaking-in of an engine, comprising halting a throttle valve controlling admission of air-fuel mixture to the engine in an idling position of the engine by a stopper member and gradually and automatically shifting the halted idling position of the throttle valve in its closing direction to diminish the flow of air-fuel mixture to the engine to compensate for increased engine idle speed upon breaking-in of the engine. The gradual and automatic shifting of the idling position of the throttle valve is obtained by constructing either the throttle valve, or the stopper member or both with contact portions which are relatively easily worn or deformed so that as the portions undergo gradual wear or deformation, the throttle valve gradually moves in its closing direction to compensate for increase engine idle speed.
    • 一种用于在发动机断开时补偿发动机怠速增加的方法和装置,包括停止节流阀,其通过止动构件控制在发动机怠速位置使空气 - 燃料混合物进入发动机并逐渐且自动地移动 节气门在其关闭方向上的停止怠速位置,以减少空气 - 燃料混合物流向发动机的流量,以补偿发动机分解时发动机怠速的增加。 节流阀的怠速位置的逐渐和自动变速通过构造节流阀或止动构件或者两者都具有相对容易磨损或变形的接触部分,从而当部件经历逐渐磨损或变形时, 节流阀在其关闭方向逐渐移动,以补偿发动机怠速的增加。
