Fuel Supply
A safe operation of an engine with fuel injection is only given if the fuel supply is secured with
sufficient pressure in the system. Carburator icing is impossible; vapour lock appears, due to the high
pressure in the system, only under very special conditions. The fuel is sucked out of the fuel tank,
trough the pre-filter with the water separator, toward the fuel pump. After the fuel pump the fuel is
pressed through the fine-filter into the common rail system. The injectors gets the required quantity
of fuel and the rest is pushed back again into the fuel tank. A pressure regulation valve in the back
flow system keeps the pressure of the entire system constant. The permanent circulation in the
system avoids an excessive heating of the fuel in the area of the engine and assure a permanent and
autonomous ventilation of the system.
Troubles in the fuel supply may lead to less performance, unsteady running, higher consumption, and
even to a total failure.
As prevention the fuel supply system should be inspected regularly for leakages, damages or
abnormal signs of use. It is also very important to ensure that no fuel pipes are bended or porous and
that all hose clips are tighten. Further it is important that all electric connections are well fixed.
