The system of heating fuel
To increase the yield of diesel fuel at low ambient temperatures must be heated. Heated made further pumping fuel that is returned from the high pressure fuel pump to the fuel tank. Passing through the high pressure fuel pump fuel is heated. The fuel return conduit installed control valve, which controls the fuel flow depending on the temperature of the fuel filter. When the outdoor temperature is below + 15 ?� C fuel, warmed high pressure fuel pump is directed to the fuel filter. When the air temperature above + 31 ?� C control valve directs fuel, warmed high pressure fuel pump to the fuel tank. Control valve located on the upper side of the fuel filter. If the engine does not run at low air temperatures due to thickening of diesel fuel, follow these steps: - Remove the fuel filter and warm up its ferry;
- Replace the fuel filter with a new;
- Warm up the injection device by spraying it with hot water.
