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).
