Preheating plugs
They are used to preheat the precombustion chamber of admission
to facilitate starting
 

 

Relay of pre-heating : Automatically cut off the supply of the preheating plugs.

 

 

Thermostart
Used on certain models to heat the ingoing air

Carry injecting
Element screwed in the cylinder head receives the arrival of the gas oil. It includes/understands: the injector, a spring and spacers for the adjustment of the opening of the injector.

Injector
One by cylinder, pulverizes the gas oil in the room of

Pumps Injection rotary

(indirect and direct Injection except common rail)
Pressurize the fuel and sends it towards the door injector,la pressure opens successively each injector to distribute the fuel in the cylinders.
They are always equipped with an electro-valve which cuts the fuel arrival. They are often coupled with a calculator on the most recent models.

Electromagnetic sluice gate

Electric element cutting the arrival of carburantà the injection pump.
Is located on the top of the injection pump.

With the origin of the following breakdowns:
On traditional Diesel engine without contribution of electronics:

O The engine does not stop
O The engine does not start Pa S

Filter the gas oil before its arrival with the pump
of injection.
Its action is paramount it is the true rampart for your engine against the impurities and the residues of water.
Its replacement must be made imperatively
according to the data manufacturer.
To supervise more closely still for the engines
with common rail and injector pumps
