装置。 Solenoid 3 is connected to the stop lever of the engine governor via a link to stop the fuel when the power is not on and release the fuel cut when the power is on, and it is turned ON when the engine does not overheat and turned OFF when the engine is overheating. a water temperature switch 4 that operates when the engine oil pressure is above a certain value P1 , and an oil pressure switch 5 that operates off when the engine oil pressure is below P1 ; and a relay 6.
When the engine oil pressure is higher than P1 , it is turned off (OFF) and when the pressure is P2 or more, it is turned on (ON).
) A hydraulic switch 7 that operates, a rotation sensor 8 that operates when the engine speed is higher than the engine's low idle speed and lower than the rated engine speed N, and turns OFF when the engine speed is below N; The start switch 2, timer 9, water temperature switch 4, and solenoid 3 are connected in series to the power supply, and the start switch 2, rotation sensor 8. The hydraulic switch 7 and the coil 6a of the relay 6 were connected in series to the power source, and the starting switch 2, the hydraulic switch 5, the contact point 6b of the relay 6, the water temperature switch 4, and the solenoid 3 were connected in series to the power source. An engine oil pressure drop protection device characterized by:
