GENERAL INFORMATION

System of injection of fuel

System of injection of fuel of the motor ONS

1 - entry road,

3 - turns regulator of wasting time,

4 - the sensor of the temperature of cooling the liquid,

5 - pressure regulator,

6 - sensor of temperature of fuel,

^{Alternation of system of injection of fuel of motors V6 2,4 and 2,9 dm3}

The alternations are located below the panel of the passenger.

1 - power alternation,

2 - alternation of the bomb of fuel

In systems of the cars of the injection of the fuel of Bosch L-Jetronic or Bosch K-Jetronic it can be installed. Control practises of the module EEC IV (Engine Control MK IV electronic – electronic control for the motor) that also the system of the ignition makes working.

The fuel below the pressure developed by the fuel pumps movements he was seeing the accumulator of the pressure and the filter of fuel. The air consumption is regulated by a butterfly valve depending on the provision of a pedal of a gas pedal. The amount of the air that comes to motor cylinders for a fluxômetro is the main size the operational process of a smeseobrazovaniye.

The fuel mouths receive electric impulses: an impulse in a turn of an end of inclination. The mouths of fuel of the work of motor DOHC in couples of impulses of the module EEC IV and fuel inject for the couple of mouths in whole world a meiovolta of an end of inclination. The duration of an impulse depends on the amount of the bloodshot fuel. The duration of an impulse is calculated by the module EEC IV on basis of the information of several sensors. A fuel mouth is installed in each cylinder.

The air that is absorbed by the motor passes by the instrument of measuring of an air current. In motors V6 two instruments of measuring of a draft are installed. The plate of fluxômetro in the instrument of measuring turns away in the proportion to the current size: this detour is going to be transformed to an electric sign of the module EEC IV. The adjusted secondary passage of the channel secures the functioning of motor to waste time.

The sensor of the provision of a valve of butterfly informs to the module EECIV to provision of a valve of butterfly and the speed of the modification of the provision of a valve of butterfly, so, during the sharp opening of the door of the acceleration of the car the additional provision of the fuel is supplied. For the economy of the fuel there is a system of the stoppage of the provision of the fuel in the way that curbs the motor.

The turns of wasting time address for the valve termelétrica of a jet that regulates the amount of the air that goes round a butterfly valve in the additional channel. The zolotnik addresses for the module EEC IV. The straight turns agreement of wasting time is not supplied.

The sensors located in the motor supply one dosage right of the fuel in the whole power placing in any surrounding temperature. In models with the automatic exchange the sensor registers the position of the coulisse of a box of P – parking or N – neutral situation, D – I advance, causing the corresponding modification of turns of wasting time. The additional sensors of the report of motor DOHC to the module EEC IV the fuels given on temperature, temperature of cooling the liquid, the speed of the movement of the car (the sensor is located in the transmission).

In the presence of the air condicionador, the sign of the compressor gives the possibility of the installation of turns to waste time independent of the load created by the compressor of condicionador.

In models with the motor DOHC without the agreement of catalyst of the mixture of wasting time it is executed by the potenciômetro that joins straightly to the EEC IV block. In models with the motor DOHC with the convertedor the sensor of oxygen of gases of leak allows to the module EEC IV there makes working the mixture of air of the fuel so that it corresponded to work parameters. So, the manual perfect syntonization of the mixture is impossible.

In models with the motor DOHC with the catalyst the system of the capture of the evaporation of the fuel is installed. The system touches an exit of evaporation of gasoline in the atmosphere. When the ignition is put out, one adheres of the fuel tank they come to a coal box. When the motor works, the module EEC IV opens the valve eletromagnética and they come to an entry collector and mix with the pure air. It compensates for the filter from coal. The special valve prevents the blow of air got absorbed in the tank of fuel.

The "limited way" (LOS) that it allows in case of failure of the module or sensors of the system of the injection of the fuel is supplied in the module EEC IV to direct the car, though with the loss of the power.

Of the way of 1.986 all the models are supplied with the switch inercial of the fuel bomb. The switch interrupts an electric chain of the bomb in case of accident or I punch strongly. The switch is for the left of the lock of lid of trunk below a plastic hat. The inclusion is done when the button is insisting on the superior part of the switch.
