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

General information

For the purpose of decrease in level of issue in the atmosphere of the toxic components getting to composition 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 the decrease in fuel consumption considered in the real Management cars are equipped with a number 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 from year of release of models and the region, on whose market the car is delivered. Full information on type to structure of systems is provided on the information label of VECI fixed under a cowl (see. Introduction).

The scheme of laying of hoses can be provided on separate шильде.

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

  1. System of a pulse podmeshivaniye of air (PAIR);
  2. Catalytic converter;
  3. System of catching of fuel evaporations (EVAP);
  4. The system of a retsirkulyatsiya of the fulfilled gases (EGR) – is used only on diesel engines;
  5. System of operated ventilation of a case (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 office of the company manufacturer.

Functioning of all listed systems, anyway, directly or indirectly, is connected with management of decrease in toxicity of the fulfilled gases. In the Sections provided below 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 amateur mechanic are stated

Before coming to conclusion about refusal any of systems of decrease in toxicity, attentively check serviceability of functioning of power supply systems and ignition (see. Heads of the Power supply system and production of the fulfilled gases and engine Electric equipment). Diagnostics of systems of decrease in toxicity some of knots demands use special, difficult in application, the equipment and a certain qualification of the performer, and therefore, it will be reasonable to charge its performance to professional mechanics of specialized car repair shop. Told does not mean above 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 violation of quality of vacuum or electric contact connections, and therefore, first of all always it is necessary to check a condition of electric sockets and shtutserny connections of vacuum lines (address to illustrations above). The owner of the car can independently and it is rather easy to make a number of checks, and also, to execute in house conditions a 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 operation of the engine get. Before starting performance of any procedures on repair of knots and details of data of systems, consult about conditions of observance of these obligations in representation office of the Toyota company.

Try to observe everything the 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 placement of components on the car. Such discrepancies are connected with continuously occurring process of updating within a standard design of each model.
