When the engine is running in a sudden flameout refers to the work of the engine, in the case of the throttle is not released, the driver of the non operating factors and rapid flameout, flameout can not start again. The phenomenon is generally caused by mechanical failure.
The reason
Fuel injection pump drive gear, gear failure.
Fuel injection pump shaft broken.
The Baotou beiben heavy duty truck accessories internal movement of engine parts stuck.
The Baotou beiben parts of fuel injection pump control rod and a connecting pin off.
The diagnosis and treatment methods
The sudden shutdown of the engine in operation is the most common, mainly caused by the ignition failure of the circuit. Diesel engine operation is a major cause of the sudden shutdown caused by the oil pump failure, followed by the engine internal card caused by. When this phenomenon occurs, first check whether the fuel pump rotation and oil supply.
The starter for driving the engine, if the normal rotation, observation of injection pump camshaft rotating. If the rotation is normal, indicating a fault injection pump. The operation of the operating mechanism should be checked. Can the throttle lever connecting view control arm, steering shaft is good.
If the camshaft of the fuel injection pump does not rotate, the camshaft gear fastening bolt is loosened, the camshaft is broken or the gear fault in the gear chamber is broken.
If Baotou beiben fittings starter drives the engine can not operate, then that is the internal fault of engine. As between the piston and the cylinder clamping, bite the crankshaft and bearing, plunger block and the gas distribution mechanism of mechanical failure etc.. Open the valve chamber cover under normal conditions. If the operation from the instrument to reflect the oil pressure is too low or the temperature is too high, it is necessary to direct the specific situation for maintenance.
