PURPOSE:To ensure the stopping of the engine by a method wherein the conducting of an actuator solenoid is interrupted by the exstence of the conditions in which an ignition switch is being made OFF, the speed of a car is zero or the revolving number of the engine is higher than the predetermined value. CONSTITUTION:An engine revolving number signal SN, the signal Ss of a spill position senser 25 or the like are inputted into an unit 3, controlling the control valve 26 of a pump plunger 15, which is feeding fuel to an injection nozzle 2 and regulating a fuel injection timing and fuel injection amount, and also a solenoid 22 driving the plunger 15, while an ignition senser 49, a car speed senser 51 and an engine revolving number detector 53 are connected to the unit 3. The unit 3 cuts the conducting of the valve 26 when the ignition switch (not shown in the diagram) is made OFF, further, decides the valve 26 as abnormal when the car speed is zero but the revolving number of the engine is still shown after five seconds after switch-OFF, and puts ON a lamp 10 and cuts the conducting of the solenoid 22 to stop the engine. |
