General information and safety measures

Petrol models

The composition of the fuel system are: installed in the rear of the car (under the rear bench seat) fuel tank to the adsorption on activated carbon, fuel, electric fuel pump, and the electronic system of sequential injection, controlled by the control unit.

Fuel is displayed to the driver on the instrument panel. In the gasoline engine gasoline vapors are collected in the absorber and fed into the combustion chambers of the engine.

A significant impact on fuel consumption has a style of driving. Below are a few tips for the wise management of the gas pedal.

• After starting the engine once started, even if it takes place in the cold;
• When the vehicle is stopped for more than 40 seconds, turn off the engine;
• Move always on the highest possible transmission;
• When driving long distances as far as possible to maintain a uniform speed. Avoid driving at high speed. Operate the vehicle with caution. Without need do not brake;
• Do not carry unnecessary burden is not a car. If the trunk is not in use, remove it from the roof;
• Check the air pressure in the tires. Avoid excessive pressure drop.

Diesel models

The composition of the fuel system are: installed in the rear of the car (under the rear bench seat) fuel tank, fuel filter, fuel injectors, fuel pipes and hoses, fuel reserve sensor located inside the tank and the engine electronic control unit.

Fuel is supplied through a special pump filter. In the filter accumulates dirt and the water contained in the fuel.

The motor controlled by an electronic system, a control system similar to petrol engines. The system controls the operation of the engine, analyzing information from a large number of sensors.

On diesel models, no accelerator cable. Instead, the pedal position sensor is installed it.

Fuel shut-off valve when the ignition is absent. In order to stop the engine when the ignition, the engine control unit sends a signal to pump control unit which, in turn, stops the supply of fuel to the injectors.

The fuel system is designed in such a way as to prevent "choke" the absence of air in the fuel tank. The control unit continuously checks the fuel level in the tank, processing information from the sensor supply of fuel in the tank. In the fall of fuel supply to a certain level the control unit activates the warning lamp in the instrument cluster, and then forcibly causes the fuel supply passes, thereby limiting the maximum speed. This continues until the fuel level in the tank does not exceed the allowable mark.

Fuel system Diesel engines are very reliable. When using cleaner fuels and performing regular maintenance, it must function properly until the end of life of the vehicle. After a very high mileage internal components can wear out nozzles, and will need to be repaired. Since the pump - nozzle have a complex construction, repair is recommended to a specialist workshop.

Security measures and rules of observance of cleanliness at work with fuel system

When working on the fuel system, observe the following safety precautions and cleanliness:

• Do not go near the place of work with open fire, do not smoke and do not include any heating appliances! Keep a fire extinguisher at the ready;
• Watch for normal ventilation of the workplace, - fuel vapors are poisonous;
• The fuel system is pressurized. With the opening of the fuel can escape under pressure - use protective glasses. Spilled fuel collect rags;
• When working with the components of the power supply system of the diesel engine, observe special precautionary measures. In particular it concerns the injectors. Keep in mind that the fuel pressure at the outlet of the nozzles is about 1,100 atmospheres, - do not expose any part of the body under the stream of fuel;
• Hose connections are secured using tape or clamps. Clamps must always be replaced by the band clamps or final design. To install the belt clamps Special tools are available (for example, HAZET 796-5);
• Links and adjacent space before opening thoroughly clean;
• The removed components install on a clean surface and cover with polyethylene, paper or lint-free cloth;
• Carefully cover the exposed ends of the connectors choke or clog them suitable plugs;
• On-site only clean parts - Replacement Parts unwrap just before installation. Do not use the stored unpackaged items;
• Avoid the use of compressed air at an open fuel system, if possible, try not to move the car;
• Do not use sealants containing silicone - trapped in the engine silicone particles do not burn, and can cause failure of the oxygen sensor.

Safety precautions when removing the fuel tank

• Before removing the tank, drain the fuel or the fuel pump out specially provided for this pump;
• The fuel tank is removed from the underside of the vehicle. Before removing the clamps securing the tank, move it to the bottom of the jack and the pad;
• The empty tank is explosive and can not be reclaimed as such. Before disposing of the tank should be cut into pieces. Make sure that when it did not have the spark. To do this, turn in the fuel tank to a specialized company;
• After installation of the tank in place, start the engine and check the tightness of all connections.
