The considered cars are equipped with several systems of decrease in toxicity of exhaust gases. Treat them:
– onboard system of diagnostics (OBD system);
– control system of the engine (EFI system);
– system of recirculation (EGR system);
– system of catching of vapors of gasoline (EVAP system);
– system of compulsory ventilation of a case (PCV system);
– system of the choice of the channel of absorption (ACIS system);
– catalytic converter.
| The concrete type of the applied systems with the indication of adjusting data is specified on podkapotny plates (VECI plate). |
