Abstract

PURPOSE: To promote warming of the three element catalyser as well as to clean the exhausted gas by rarefying the general air fuel ratio of the front stream of the three element catalyser when much HC and CO are exhausted with less NOx generated in the air fuel ratio controller of the engine having three element catalyser.
