Diesel Fuel Supply System — Basic Design Unlike petrol engines, diesel injection systems operate under high pressure. As a result, injection pumps, including process-regulating peripheral units, are very...
Excess fuel is returned to the fuel tank Given the amount required for full load, more fuel is circulating in the injection system than is actually needed. The injectors also do not inject all the fuel into the...
Fuel supply path — this is how fuel enters the injector The fuel pump delivers diesel fuel from the fuel tank through the fuel filter to the injection pump in a closed fuel system (supply and recirculation fuel lines)....
Wheel pulse encoder and angle encoder In order for each cylinder to receive its particular portion of fuel in the right sequence and at the right time, the encoder wheel and angle sensor function to a...
Cold start equipment for diesel engine The cold start equipment for a diesel engine plays the same role as an automatic starter for a gasoline engine: both systems help a cold engine start. But that's where...
Injectors — diesel atomization Injectors are the last link in the fuel injection system in a diesel engine. They spray fuel at high pressure into the combustion chambers. In order to minimize...
Disassembly of nozzles Direct wear occurs inside the nozzle, in the needle, in the nozzle body and compression springs. There you have little room for correction, unless you have an injector...
Visual inspection of the diesel injection system Checking the tightness of the injection pipeline. Checking the tightness of the return pipelines. Checking the tightness of the housing cover of the distribution pump....
