Abstract (en)
[origin: US4815435A] Process for correcting the richness of an air-fuel mixture admitted into an internal combustion engine with electronic ignition of the pressure-speed type, to obtain a constant richness as a function of the air temperature entering the cylinders, wherein the correction is of the multiplicative type: Ti=Tin (1+( alpha air)/256) alpha air=f(T') T'=T+k(Twater-T) k=k1(N)+k2(P)+k3 wherein: alpha air is term of correction of the richness as a function of the air temperature T' actually entering the cylinders; T is the temperature of the air measured by the injection computer; and Twater is the water temperature of the engine.
