摘要： An electronic throttle control unit includes an air bypass channel having a removable obstruction that opens in response to receiving an electronic throttle control fault signal and thereby allowing the vehicle a limp home condition. The throttle plate defaults to a fully closed position upon engine-off to substantially prevent evaporation and escape of hydrocarbons from the intake manifold to the atmosphere.

摘要： A speed control apparatus for an internal combustion engine including a poppet valve seat and a poppet valve pintle assembly disposed coaxially for variably regulating the flow of air into the engine across the valve seat. The pintle is axially positioned by a stepper motor actuator responsive to an engine speed sensor and electronic controller. The controller varies the axial position of the pintle in accordance with a programmed algorithm to provide any desired engine speed, and especially a fixed engine speed, under a range of engine loads. The invention eliminates the need for a governor, rotary mechanical throttle, and cable or mechanical linkages, and is especially useful for small engine applications such as in powering a portable electric generator, yard equipment, or outboard motor.

摘要： A rotational speed damper operable to dampen the speed of a gear by gradually decreasing the rotational velocity and angular acceleration of the gear over a time period beginning at the time the damper contacts the gear stop and ending at the time the gear reaches its first stopping point.

摘要翻译： 一种用于内燃机的速度控制装置，其包括提升阀阀座和同轴设置的提升阀枢栓组件，用于可变地调节穿过阀座的发动机的空气流。 枢轴由响应于发动机转速传感器和电子控制器的步进电机致动器轴向定位。 控制器根据编程的算法改变枢轴的轴向位置，以在发动机负载范围内提供任何期望的发动机转速，特别是固定的发动机转速。 本发明消除了对调速器，旋转机械节流阀，电缆或机械联动装置的需要，并且特别适用于小型发动机应用，例如为便携式发电机，场地设备或舷外马达供电。
