When the engine is started, the exhaust pipe is discharged without smoke, and no explosion sound.
The reason
No oil in oil tank.
The fuel filter clogging, oil-water separator.
Low pressure oil supply.
The injection pump pump oil.
With the passage of the air.
The gas phase misalignment. The opening time of the valve is incompatible with the stroke of the piston in the cylinder. If the piston in the cylinder for compression stroke, the intake and exhaust doors open, fresh air was expelled from the cylinder, so that the cylinder is not burning gas, can not start.
The injection pump electromagnetic valve is bad, in a closed state, can not enter the high pressure chamber of diesel engine.
The diagnosis and treatment methods
Principle: first, after the first, after the first easy difficult
Look at the injection pump is back to pull off.
Whether there is oil in the oil tank, the oil tank switch is open.
The Baotou beiben parts of fuel injection pump and drive control rod fastening bolt connecting plate.
To loosen the bleed screw on fuel injection pump, hand pump oil pump exhaust.
Inspect Baotou beiben tubing fittings for leaks or blockage.
Check the fuel filter and water separator is blocked.
The starter with the engine rotation, check Baotou beiben pump oil pump whether accessories.
The remove loose injector inlet pipe joints, and throttle in the end, press the starter switch, check the fuel pump or pump oil pump oil, if not, explain the oil amount regulating rod stuck in stop oil position (i.e. rack hairpin); if the A_ type pump, should remove the fuel pump side cover check and troubleshooting; if P_ type pump, should take appropriate measures to deal with.
To check the gas distribution phase is accurate, if it is not on, should be adjusted.
For the VE pump engine, check the solenoid valve and the control circuit is faulty. When the solenoid valve is damaged, and can find new electromagnetic replaced immediately, can be used to remove the solenoid valve, remove the plunger valve and the spring back is refitted, and take emergency measures to deal with power outages on the electromagnetic valve (this method cannot electrical flameout, you can manually turn off).
