7.9. System of electronic injection of fuel - general informationCars are equipped with system or preliminary preparation of a mix (TBI system) or direct injection of fuel in cylinders (MPF system). Systems of injection of both types cope the processor ECCS block and work together with many units of system of decrease in toxicity of exhaust gases. Such system is known as system of electronic injection (EFI) and consists of 3 subsystems - control and measuring, dispensing of fuel and air injection. The amount of injected fuel is defined by duration of an open condition of a nozzle which is automatically regulated by the ECCS block on the basis of the data which are read out from various sensors.

Necessary precautionary measures
а). It is forbidden to disconnect the battery on the working engine.
б). Before depressurization of system execute a decompression.
в). Before removal of any unit of system disconnect the battery from weight and turn the ignition key in the situation Off.
г). Conducting plaits" systems should lie not less than in 10 mm from other plaits (including an aerial cable),
д). Check reliability of all connections as in bad contacts will arise sincere from breakdown in candles and the ignition block will fail.
е). Before start-up of the engine it is forbidden to press a butterfly valve pedal.
ж). Keep in mind that operation of the fuel pump some relays operate. After an engine stop the pump is disconnected under the influence of pressure drop and tension signals on the generator.
