Abstract

PROCEDE POUR CONTROLER L'EMISSION DES GAZ D'ECHAPPEMENT D'UN MOTEUR A COMBUSTION INTERNE, NOTAMMENT POUR VEHICULES A MOTEUR. IL EST CONSTITUE PAR UN CONTROLE DU POINT D'ALLUMAGE AU RALENTI, UN CONTROLE DE RICHESSE L AU RALENTI, AU MOINS UN CONTROLE DE RICHESSE L AUX VITESSES DE ROTATION LE LONG DE LA COURBE DE CHARGE ZERO. APPLICATIONS AU CONTROLE DE POLLUTION DES MOTEURS D'AUTOMOBILE.PROCESS FOR CONTROL OF THE EMISSION OF EXHAUST GASES FROM AN INTERNAL COMBUSTION ENGINE, IN PARTICULAR FOR MOTOR VEHICLES. IT IS CONSTITUTED BY A CONTROL OF THE IGNITION POINT AT IDLE, AN L-RICHNESS CONTROL AT IDLE, AT LEAST ONE L-RICHNESS CONTROL AT ROTATION SPEEDS ALONG THE ZERO LOAD CURVE. APPLICATIONS TO THE POLLUTION CONTROL OF AUTOMOTIVE ENGINES.
