GENERAL INFORMATION

Places of installation of units of standard system of decrease in toxicity on the 4-cylinder engine of 2,7 l

1. Retsirkulyatsiya valve
2. The vacuum valve operating
retsirkulyatsiya valve
3. Vacuum distributor,
managing director of the retsirkulyatsiya valve
4. Converter

5. Oxygen sensor
6. Control valve
7. A tank with an absorber паров gasoline
8. The vacuum distributor operating the valve of a tank

Vacuum hoses on the engine of V6 3,4 l

1. Zolotnik of ventilation of a case
2. Retsirkulyatsiya valve
3. The vacuum valve operating the valve of a retsirkulyatsiya
4. The vacuum distributor operating the valve of a retsirkulyatsiya

5. Sensor паров gasoline

9. Oxygen 2 sensor

The cars considered in this Management, are equipped with several systems of decrease in toxicity of exhaust gases. Concrete execution of system of protection of environment is defined by make of the car and the territory of its sale. The specified systems treat:

– system of compulsory ventilation of a case (PCV system),
– catching system паров gasoline (EEC-system),
– system of a retsirkulyatsiya of exhaust gases (EGR system),
– catalytic converter (TWC),
– pulsatsionny system of a dookisleniye of exhaust gases (PAIR system).
– onboard system diagnostics (OBDII-system).

The concrete type of systems with the indication of adjusting data and distributings of vacuum hoses is specified on the podkapotny plate (VECI plate).

Failure of sensors and devices of some systems of decrease in toxicity can affect operational characteristics of the engine. Reading of diagnostic codes and exact establishment of the concrete faulty device is possible thanks to application on the car of system of onboard diagnostics of OBDII (since 1996). For reading in this system of diagnostic codes of malfunction and their identification special expensive scanners therefore all types of works on diagnostics, it is expedient to repair and adjustment to carry out in car-care center are required.
