In the diesel engine operation, the sudden increase of the rotational speed occurs at a high speed, and the faster and faster, even if the throttle is pushed to the minimum position, the rotational speed cannot be reduced. This phenomenon is called “speed racingâ€. If it is found that the sudden increase in the engine speed and abnormal noises occur at the same time, emergency measures must be taken to stop the vehicle immediately, otherwise serious accidents will occur. There are the following reasons for the firewood pumping: The failure of the governor is mainly due to:
(1) The governor spring breaks.
(2) The governor fly or steel ball falls off.
(3) Excessive oil in the governor affects the inertial action of the flyweight and does not allow sensitive control of the fuel injection. Fuel injection pump adjustment mechanism fails:
(1) The rack and lever are disconnected.
(2) The fuel pump adjusting gear rod or lever is stuck.
(3) Excessive combustion oil. Because the oil level in the oil pan is too high, the temperature is too high, or the piston ring leaks, the oil is sucked into the cylinder and burned. The common emergency treatment methods encountered by the speeding car are: disconnect the high-pressure fuel pipe; block the air filter; press the decompression handle plate to the decompression position, etc., to force the diesel engine to extinguish.
