    • The specification discloses a motor kill system for automatically shutting off and killing an internal combustion engine to prevent damage to the engine from obstruction of the air cleaning system. The motor kill system includes a vacuum switch operating in response to a drop in the pressure between the air cleaning system and the intake manifold of the engine caused by obstruction of the air cleaning system. The preferred embodiment of the invention utilizes a normally open vacuum switch that closes to cause a solenoid to operate a butterfly valve to cut off the air supply to kill the engine. An alternate embodiment of the invention utilizes a normally closed vacuum switch which operates in response to obstruction of the air cleaning system to open the circuit between the ignition and the fuel pump to cut off the fuel supply and thereby kill the engine before any damage is done.
    • 本说明书公开了一种用于自动关闭和杀死内燃机以防止发动机受到空气净化系统阻塞的电动机停止系统。 电动机停止系统包括真空开关,该真空开关响应空气净化系统与由空气净化系统的阻塞引起的发动机的进气歧管之间的压力的下降而工作。 本发明的优选实施例利用一个常开的真空开关,该真空开关闭合以使螺线管操作蝶阀以切断空气供应以致死发动机。 本发明的替代实施例使用常闭真空开关,其响应于空气净化系统的阻塞而操作,以打开点火和燃料泵之间的电路,以切断燃料供应,从而在发生任何损坏之前杀死发动机 。
