    • An ignition distributor cap having a first capacitor for detecting ignition voltage of a spark-ignition internal combustion engine to determine if misfire occurs. The ignition distributor cap has a coil contact tower connected to the secondary winding of an ignition coil of the engine, spark plug terminals connected to spark plugs of the engine, and a rotor connecting the coil contact tower to one of the spark plug terminals with a gap to generate an electric path carrying ignition voltage current produced at the ignition coil to the spark plug. In the ignition distributor cap, a conductor is located around the electric path keeping a predetermined distance from the electric path and forming a first capacitor such that the first capacitor constitutes a capacitive divider with a second capacitor for ignition voltage detection between the electric path and the conductor positioned at the coil contact tower or the individual spark plug terminals. A ceramic insulator can be positioned between the conductor and the electric path. The conductor can further be electrically shielded.
    • 一种点火分配器盖,具有用于检测火花点火式内燃机的点火电压的第一电容器,以确定是否发生失火。 点火分配器帽具有连接到发动机的点火线圈的次级绕组的线圈接触塔,连接到发动机的火花塞的火花塞端子和将线圈接触塔连接到火花塞端子之一的转子, 间隙以产生在点火线圈处产生的点火电压电流到火花塞的电路径。 在点火分配器盖中,导体位于电路周围,与电气路径保持预定的距离,并形成第一电容器,使得第一电容器构成电容分压器,其中第二电容器用于电路和电路之间的点火电压检测 导体定位在线圈接触塔或单个火花塞端子上。 陶瓷绝缘体可以位于导体和电路之间。 导体可进一步电屏蔽。

    • In a default device of an actuator for a variable lift valve operating mechanism, in the event of failure of the actuator, a pressed portion of a lever pivotably supported on a support shaft is urged by a resilient force of a coil spring, an arm is pressed by a cam portion of the lever to rotate a control shaft in one direction to prevent valve lift from being a predetermined value or lower. The support shaft that pivotably supports the lever of a default mechanism is placed in a position offset from a rotation axis of the control shaft. Thus, as compared with the case where the support shaft is placed coaxially with the control shaft, a large urging force is input from the lever to the control shaft to reliably prevent the valve lift from being the predetermined value or lower.
    • 在用于可变提升阀操作机构的致动器的默认装置中,在致动器发生故障的情况下,可枢转地支撑在支撑轴上的杠杆的按压部分被螺旋弹簧的弹力推动,臂是 由杠杆的凸轮部分按压以使控制轴沿一个方向旋转,以防止气门升程达到预定值或更低。 可枢转地支撑默认机构的杠杆的支撑轴被放置在偏离控制轴的旋转轴线的位置。 因此,与支撑轴与控制轴同轴配置的情况相比,从杠杆向控制轴输入大的作动力,可靠地将气门升程降低到规定值以下。
