Petrol engine

Gasoline is extremely inflammable therefore at work with any components of fuel system it is necessary to accept special precautionary measures. Do not smoke and do not come nearer to a venue of works with open fire or unprotected by the lamp shade carrying. Do not perform such works in the garages equipped with heating devices, working at natural gas (such, as водогреи, dryers, etc.). The working platform should be ventilated well. At gasoline hit on skin immediately wash away it water with soap. At carrying out any works with fuel system put on goggles and hold near at hand the fire extinguisher. In case of a gasoline spillage immediately wipe a pool, but do not keep the rags impregnated with gasoline in places where it can самовоспламениться.

CHECK

1. If you felt a gasoline smell during movement or after the car stood on the sun, it is necessary to check a condition of all fuel system immediately.
2. Uncover a fuel tank and check it on existence of damages and corrosion. The sealing insert on a cover should 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 to Head of the Power supply system and release

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

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

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

Diesel engine

Operation in winter conditions

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

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

Since addition of kerosene reduces engine capacity, the razbavleniye should be made in strictly certain proportions. Address to 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 should be made in a 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 Head.

At addition of kerosene engine capacity decreases.

If the engine is not got owing to a fuel zagustevaniye, to start it very hard. For start:
   a) Remove the fuel filter and heat up in a water bath while fuel does not become liquid., or replace it new.
   b) Roll the car in heated garage.
   c) Spray fuel system hot water.
   d) The BOSCH firm delivers a diesel heater for additional installation. The electric heater is established in the additional pipeline to the fuel filter.

At all it is not necessary to warm up system of injection or a fuel tank a blowtorch or other similar adaptation in view of danger of explosion!
