"Speeding" is a phenomenon unique to diesel engines. "Speeding" when the speed of the diesel engine is out of control, and the speed is faster and faster than the maximum allowable speed, accompanied by a loud noise, and the damage of the engine is scrapped in severe cases. There are two main reasons for causing “speed racingâ€. One is the failure of the fuel pump governor itself, which causes it to lose its normal governor characteristics; the other is that the diesel engine has additional diesel or oil entering the combustion chamber during operation. . The emergency measures should be taken after the occurrence of “speed racingâ€, otherwise accidents will occur when the engine speed is high. Emergency measures to stop speeding include: 1. Quickly retract the throttle (accelerator or accelerator pedal) to the parking position; 2. With a decompression device, quickly pull the decompression handle to the decompression position; 3. Hung up in time, step on the brake pedal, lift the clutch, and increase the engine's resistance torque; 4. Quickly disconnect the high-pressure mixing pipe and stop the oil supply; 5. Quickly tighten the air filter with clothes to make the engine "air-free". The above is referred to as "five measures for deceleration, decompression, braking, fuel cut-off, and gas shutoff."
