摘要： There is disclosed a fuel cutoff apparatus for use in an engine-driven vehicle. The apparatus comprises a fuel supply means for supplying fuel to the engine, a hydraulically actuated means that is actuated in response to the pressure of the engine oil, and a fuel cutoff control means which, when the pressure of the engine oil decreases below a certain level, is actuated in response to the actuation of the hydraulically actuated means to control the fuel supply means in such a way that the supply of fuel to the engine is cut off.

摘要： The present invention relates to a system for shutting off the LPG fuel supply route in a vehicle except in case of necessity. Namely, when an engine is stopped and a starting switch is in switched off, a solenoid valve is operated to shut off the LPG fuel supply route to prevent the LPG fuel from leaking out to the carburetor and to keep the vehicle from suddenly lurching out.
