    • A fuel injection shutdown system for a fuel injected internal combustion engine (5) having mechanical fuel injectors (11) with a return spring (13) and lifter bodies (19) slidably disposed in lifter guides (21) comprises a slot (25) formed in the lifter guides (21) to receive a hydraulic cartridge (29) and a slot (27) in the lifter bodies (19) which registers with the slots (27) in the lifter guides (21), but are longer, the hydraulic cartridge (29) extends into the slots (27) in the lifter bodies (19), as the lifter bodies (19) are reciprocated by an injection cam (19) and the hydraulic cartridge (29) does not contact the slots (27) in the lifter bodies (19) and the hydraulic cartridges (29) have a stop pin (35) slidably disposed therein and have a hydraulic duct which when filled with pressurized hydraulic fluid causes the stop pin (35) to extend from the hydraulic cartridge (29) contact the top of the slot (27) in the lifter body (19) and hold the lifter body (19) off the cam (17) preventing the fuel injectors (11) from injecting fuel into the engine (5) in two engine revolutions and stopping the engine (5) to prevent harm to the engine (5).
    • 该系统具有从升降器引导件(21)中的槽(25)延伸到燃料喷射系统的往复式升降器主体(19)中的槽(27)中的液压盒(29),并且包含被迫进入 延伸位置使得当由发动机控制器(63)致动加压液压供应时,它们与升降机主体中的槽的顶部接触。 该系统在升降机导向件中具有槽,其中接收液压盒和升降机主体中较长的槽,其与升降机引导件中的槽对准,液压盒延伸到升降机主体中的槽中,但不将其作为升降机体 由注射凸轮往复运动。 液压盒具有可滑动地设置在其内的止动销和液压管道,当填充有加压流体时,止动销从盒延伸以接触升降机主体中的槽的顶部,以便将升降机主体从 凸轮,这又防止燃料喷射器注入发动机。 电子控制模块从多个发动机传感器(65,67)接收信号,该信号在接收到指示发动机超速运行的信号或信号组合时,失去润滑油压力,或者在进行其他可能 导致发动机的主要损坏,发送信号以打开螺线管(55),以允许来自泵(57)的加压流体通过止回阀(53)进入液压盒。 止动销随着升降机主体的延伸而延伸,并且当升降机体开始在销上回降时,料筒中的压力达到其大于由泵提供的压力的点,因此止回阀关闭以隔离流体 因此防止升降机体返回任何下部。
