Cars are equipped каталитическим with neutralizer of the fulfilled gases, both diesel updatings are in addition equipped with system рециркуляции the fulfilled gases. Katalitichesky neutralizer reduces the maintenance in the fulfilled gases of carbonic oxide on 85 %, the maintenance of oxides of hydrocarbon — on 80 % and nitrogen oxides — on 70 %. The structure of exhaust gases is regulated so that to reach a minimum of the maintenance of harmful substances. With participation of the gauge of the ljambda-probe established in system of release, concentration of oxygen in the fulfilled gases is defined, the structure of the working mix arriving in the chamber of combustion changes.
