The information tablet

The tablet with the information on system of reduction of toxicity of exhaust gases and with the scheme of passage of vacuum hoses is located under a cowl.

For reduction of pollution of atmosphere from the rests of short burnt down fuel and exhaust gases, for achievement of optimum power setting and economy of fuel in the car there are some systems of reduction of toxicity of exhaust gases:

 – System of repeated burning of the fulfilled gases (EGR);
 – System of catching of steams of fuel (EVP);
 – Multidot system of injection of fuel (MPFI);
 – System of compulsory ventilation картера (PCV);
 – The catalyst.

In the given section the general description of the operations which are in the competence of the motorist, on check and replacement of some details is resulted.

Before to do conclusions about malfunction any of systems of reduction of toxicity of exhaust gases, carefully check up fuel system and ignition system. Definition of malfunctions of some of devices of reduction of toxicity demands special adaptations and experience presence.
