3.2.17. Device of injection of diesel fuel


Purity is an indispensable condition of carrying out all works on the diesel engine. Surely clear cap nuts of the pressure head pipeline to their otvorachivaniye. The fuel pump of high pressure is not subject to dismantling or repair, and at refusal is replaced. Adjustment of the fuel pump of high pressure requires the special tool and devices and adjustment should be made in a workshop. Diesel engines work either with direct, or with direct injection that is when fuel is injected in a forkamer in a head of cylinders which is connected with actually combustion chamber. Process of combustion begins in a forkamer and under the arising pressure of a particle of fuel are fond in the combustion chamber where there is their full combustion.

Precautionary measures during the works with the injection device

When carrying out any repair work with the injection device, irrespective of their volume, observe purity. Especially it is necessary to consider the next moments:

All works with the device of injection have to be performed in the conditions of absolute purity. Works on the street should be performed only in windless days to avoid dust hit.

Before an otvorachivaniye of their cap nuts it is necessary to wipe with a rag carefully.

Put all removed details on a pure workbench and cover with paper or a film. Do not cover a detail with rags with pile. If repair is not made at once, all open or partially sorted details of the device of injection have to be covered or be stored in the closed boxes respectively.

Before installation of details check their purity.

At the opened device do not use compressed air for a purge of details of the engine.

Whenever possible do not move the car at the removed injection device details.

Do not allow hit of diesel fuel on hoses. If it occurs, at once wipe hoses. The hoses damaged from hit on them diesel fuel have to be replaced surely.
