Toyota RAV4>> The control system and decrease in toxicity of the fulfilled gases>> General information
For prevention of environmental pollution from incompleteness of the burned and evaporating gases, for preservation of dynamic characteristics of the car, at economic fuel consumption, the set of systems of decrease in toxicity of the fulfilled gases is used. They include:
– system of onboard diagnostics (OBD);
– electronic system of injection of fuel (EFI);
– system of repeated combustion of the fulfilled gases (EGR);
– system of catching of vapors of fuel (EVAP);
– system of compulsory ventilation of a case (PCV);
– catalytic converter.
In this section the general information and operations of checks available to performance are given in house conditions.
If there is an assumption that the system of decrease in toxicity of the fulfilled gases works with failures, previously check fuel system and system of ignition. Diagnostics of some systems of decrease in toxicity of the fulfilled gases demands specialized tools and the equipment.
It is necessary to remember that the most frequent reason of failure of systems of decrease in toxicity of the fulfilled gases consists in break or a detachment of a wire or a vacuum hose therefore first of all check their reliability of connection and integrity.
The information plate with important data and information on regulation of the control system and decrease in toxicity of the fulfilled gases is pasted to a reverse side of a cowl. Also there is a label with charts and identification of an arrangement of vacuum hoses of control of the control system and decrease in toxicity of the fulfilled gases.
