THE GENERAL DATA

System of injection of fuel


System of injection of fuel of engine ONS

1 – an inlet highway, 2 – connection of a hose of the vacuum amplifier of brakes, 3 – the gauge of temperature of a cooling liquid, 4 – топливопровод, 5 – a regulator of pressure, 6 – the case throttle заслонки,

7, 12 – linings, 8 – sealing rings, 9 – a fuel atomizer, 10 – a fuel distributive highway, 11 – a potentiometer of position throttle заслонки, 13 – a regulator of turns of idling

System of injection of fuel of engine DONS

1 – an inlet highway, 2 – the case throttle заслонки, 3 – a regulator of turns of idling, 4 – the gauge of temperature of a cooling liquid, 5 – a regulator of pressure, 6 – the gauge of temperature of fuel, 7 – a fuel distributive highway, 8 – sealing rings, 9 – a fuel atomizer

The relay of system of injection of fuel of engines V6 2,4 and 2,9 дм³

Relays are located under the panel of devices from outside the passenger. 1 – the power relay, 2 – the relay of the fuel pump

On cars systems of injection of fuel Bosch K-Jetronic or Bosch L-Jetronic can be established. Management is carried out by module EEC IV (Electronic Engine Control MK IV – electronic control by the engine) which also operates ignition system.

Fuel under the pressure developed by the fuel pump, moves through the accumulator of pressure and the fuel filter. Air expense is regulated throttle заслонкой depending on position of a pedal of an accelerator. The quantity of air arriving in cylinders of the engine through a flowmeter, is the basic size operating process смесеобразования.

Fuel atomizers receive electric impulses: one impulse on one turn of a cranked shaft. Fuel atomizers of engine DOHC work in pairs from impulses of module EEC IV and fuel is injected by pair atomizers on everyone a half-turn of a cranked shaft. Duration of an impulse depends on quantity of injected fuel. Duration of an impulse is calculated EEC by IV module on the basis of the information from various gauges. In each cylinder one fuel atomizer is established.

Air soaked up by the engine passes through a measuring instrument of an air stream. On engines V6 two measuring instruments of a stream of air are established. The flowmeter plate in a measuring instrument deviates proportionally to stream size: this deviation will be transformed to an electric sign
