Check of fuel system. Winter operation of the Diesel

Petrol engine

Gasoline is extremely flammable therefore during the work with any components of fuel system it is necessary to take special precautionary measures. You do not smoke and do not approach the venue of works with naked flame or the carrying unprotected by the lamp shade. You do not perform such works in the garages equipped with the heating devices using natural gas (such as vodogre, dryers, etc.). The working platform has to be ventilated well. At hit of gasoline on skin immediately wash away it water with soap. When carrying out any works with fuel system put on goggles and you hold near at hand the fire extinguisher. In case of a gasoline spillage immediately wipe a pool, but you do not keep the rags impregnated with gasoline in places where it can self-ignite.


 CHECK

1. If you felt a gasoline smell during the movement or after the car stood in the sun, it is necessary to check a condition of all fuel system immediately.
2. Uncover the fuel tank and check it for existence of damages and corrosion. The sealing insert on a cover has to be whole. In case of existence of damages or corrosion replace a cover.
3. Survey inlet and returnable lines of fuel system on existence of cracks. Make sure that connections between lines of fuel system and system of injection of fuel, and also between lines of fuel system and the built-in fuel filter did not weaken.

On the cars equipped with system of injection of fuel before serving fuel hoses, it is necessary to dump pressure in system. For instructions address the Head of the Power supply system and release

4. As some components of fuel system - for example, the fuel tank and some lines of fuel system - are in the lower part of the car, it is easier to examine them when the car is raised by the winch. If it is impossible, the car and install to a poddomkratta it on support.
5. On the raised car examine the fuel tank and a bulk mouth on existence of holes, cracks and other damages. Pay special attention to a condition of connection between a bulk mouth and a tank. Sometimes leak of fuel happens owing to weakening of collars of fastening of a rubber mouth or because of mouth material damage. Examine all arms and tapes of fastening of the fuel tank to make sure that it is reliably strengthened on the car.

Never, under no circumstances, try to repair the fuel tank (excepting replacement of its rubber components). The flame of the welding machine or any other naked flame can easily lead to explosion of evaporations of gasoline in a tank.

6. Carefully check all fuel hoses and metal lines going from a tank for existence of the weakened connections, twisting, signs of wear of materials of hoses and other damages. If necessary you make repair or replace the damaged sections (address the Head of the Power supply system and release).

Diesel engine

Operation in winter conditions

Usually no additives are added to diesel fuel. But with air fall of temperature the fluidity of diesel fuel decreases, it becomes viscous as honey. For this reason of firm manufacturers of mineral oils apply the special winter additives designed to improve the fluidity and to guarantee start of the engine at temperatures up to -15 °C. However not always these additives are enough for excellent job in the winter therefore in case of filling with summer diesel fuel it is necessary to add kerosene or, as a last resort, low-octane gasoline (not AI-95) to it in the winter.

Mixing has to be made whenever possible before start of the engine since differently at first it is necessary to clean the filter and pipelines from paraffin.

Since addition of kerosene reduces engine capacity, dilution has to be made in strictly certain proportions. Address Specifications

For a dolivaniye in diesel fuel it is not necessary to use high-octane gasoline.

Because of ease of an inflammability of gasoline mixing has to be made in the fuel tank - at first to fill in gasoline, then diesel fuel. Percentage ratios for various temperatures of air are given in Specifications at the beginning of the Head.

At addition of kerosene engine capacity decreases.

If the engine is not started owing to fuel jelling, to start it very hard. For start:
   a) Remove the fuel filter and heat in a water bathtub until fuel becomes liquid., or replace it new.
   b) Roll the car in the heated garage.
   c) Spray fuel system hot water.
   d) BOSCH delivers the diesel heater for additional installation. The electric heater is installed in the additional pipeline to the fuel filter.

It is not necessary to warm system of injection or the fuel tank a blowtorch or other similar adaptation in view of danger of explosion at all!
