Control systems of the engine and decrease in toxicity of the fulfilled gases

The general information

For the purpose of decrease in level of issue in atmosphere of the toxic components getting to structure of fulfilled gases of the engine as a result of evaporation and incompleteness of combustion of fuel, and also for maintenance of efficiency of return of the engine and decrease in the expense of the fuel, cars considered in the present Management are equipped by variety of special systems which can be united under the general name of control systems of the engine and decrease in toxicity of the fulfilled gases. The complete set of systems depends on year of release of models and region, on whose market the car is delivered. The full information on type to structure of systems is resulted on information label VECI fixed under a cowl (Introduction see).

To number of the systems concerning management by work of the engine and the control over toxicity of fulfilled gases, it is necessary to carry the following:

  1. System pulse подмешивания air (PAIR);
  2. The Katalitichesky converter;
  3. System of catching of fuel evaporations (EVAP);
  4. The system рециркуляции the fulfilled gases (EGR) – is used only on diesel engines;
  5. System of operated ventilation картера (PCV);
  6. System of onboard diagnostics (OBD);

More detailed information on control systems of the engine and decrease in toxicity of the fulfilled gases of your car can be received in representation branch of the company-manufacturer.

Functioning of all listed systems, anyhow, directly or indirectly, is connected with management of decrease in toxicity of the fulfilled gases. In the Sections resulted more low the general descriptions of principles of functioning of each of systems are given, and also procedures of diagnostic checks and regenerative repair (if that is obviously possible) the separate components which performance lies within qualification of the average mechanic-fan are stated

Before to come to conclusion about refusal any of systems of decrease in toxicity, attentively check up serviceability of functioning of power supply systems and ignition (Heads of the Power supply system and release of the fulfilled gases and an engine Electric equipment see). Diagnostics of systems of decrease in toxicity some of knots demands use special, difficult in application, the equipment and certain qualification of the executor that is why, it will be reasonable to charge its performance to professional mechanics of a specialised car repair shop. Told above does not mean that service and repair of components of systems of decrease in toxicity in practice are represented exigeant. It is necessary to remember that one of the most widespread causes of failures is elementary infringement of quality of vacuum or electric contact connections that is why, first of all always it is necessary to check a condition of electric sockets and штуцерных connections of vacuum lines (address to illustrations above). The owner of the car can make independently and easily enough variety of checks, and also, execute in house conditions set of procedures of routine maintenance of the majority of components of systems, using thus a usual set of the adjusting and metalwork tool.

Do not forget about additional federal guarantee certificates under which components of systems of decrease in toxicity and management of engine work get. Before to start performance of any procedures on repair of knots and details of the given systems, consult about conditions of observance of these obligations in representation branch of company Toyota.

Try to observe all measures of precautions stipulated in below-mentioned Sections at performance of service of electronic components of considered systems. It is necessary to notice that the illustrative material can correspond not always in accuracy to real placing of components on the car. Such discrepancies are connected with continuously occurring process of updating within the limits of a typical design of each model.
