Diesel injection system

THE DIESEL INJECTION SYSTEM

- Control on the different elements of a rotary injection pump;

- Disassembly and reassembly of a rotary injection pump

- Questions and problems

- Real or simulated cases or representative vehicles

The diesel engine is a self-igniting engine that sucks in only air and compresses it. This process provides significantly greater compression than the knock-sensitive gasoline engine with a mixture of air and fuel and controlled ignition.

Features of a diesel engine

Advance at admission opening (A.O.A)

Delayed closure of admission (R.F.A)

Advance on ignition (A.A)

Advance at the opening of the exhaust (A.O.E)

Exhaust Closing Delay (R.F.E)

Transfer phase

By turning, the camshaft of the injection pump brings the eccentric (1) to the high position. The piston (4) is pushed upwards by the roller (2) and the rod (3). The displacement of the piston causes the shutter (6) to close under the effect of the fuel pressure in the chamber (7), the valve (8) moves away from its seat, the gas oil contained in the chamber (7) s flows towards the chamber (9) it is the transfer phase.

Self-regulating phase


The flow rate of the feed pump being greater than the flow delivered by the injection pump, there comes a time when the pressure in the chamber (9) is equal to the pressure of the spring (5) on the piston (4); it can no longer move, there is no aspiration or repression: it is the self-regulating phase. Recall that the roller (2) is always in contact with the eccentric (1) via a return spring not shown in the diagram.
