Diesel Fuel Supply System — Basic Design
Unlike petrol engines, diesel injection systems operate under high pressure. This makes injection pumps, including the peripheral units that regulate the process, very...

Excess fuel is returned to the fuel tank
Considering the amount required for full load, more fuel circulates in the injection system than is actually needed. The injectors also do not inject all the fuel into...

Fuel Delivery Path — This is how fuel gets to the injector
The fuel pump delivers diesel fuel from the fuel tank through the fuel filter to the injection pump in a closed fuel line system (supply and recirculation fuel lines)....

Significantly increased hydraulic efficiency — VP 30 injection pump
The pump control unit (PCU) on the top of the pump functions as a central link - it has no mechanical connection to the accelerator pedal. The Bosch VP-30 controls a...

Pulse sensor wheel and angle sensor
In order for each cylinder to receive its specific portion of fuel in the right sequence and at the right time, the pulse sensor wheel and the angle sensor function to...

Equipment for starting a cold diesel engine
The cold start equipment for a diesel engine plays the same role as the automatic starter for a petrol engine: both systems help a cold engine to start. But that is...

Injectors — Diesel fuel atomization
The injectors are the final link in the fuel injection system of a diesel engine. They spray the fuel under high pressure into the combustion chambers. In order to...

Repair and correction of the injection system in a diesel engine
Experienced amateurs can even detect a single defective injector on their own. Start the engine to idle and then alternately loosen the union nut of the injection...

Disassembling injectors
The actual wear is inside the injector, in the needle, in the injector body and the pressure springs. There is little room for improvement unless you have an injector...

Visual inspection of the diesel engine injection system
Checking the tightness of the injection pipeline. Checking the tightness of return pipelines. Checking the tightness of the distribution pump housing cover. Check the...
