Abstract

Abstract Translated from French Procédé de correction de la richesse d'un mélange air-carburant admis dans un moteur à combustion interne à injection électronique du type pression-vitesse, pour obtenir une richesse constante en fonction de la température d'air entrant dans les cylindres, caractérisé en ce que la correction est du type multiplicative : <IMAGE>avec :- α air : terme de correction de la richesse en fonction de la température d'air T' entrant réellement dans les cylindres ;- T : température de l'air mesurée par le calculateur d'injection ;- T eau : température d'eau du moteur. Method for correcting the richness of an air-fuel mixture admitted into an internal combustion engine with electronic injection of the pressure-speed type, in order to obtain a constant richness as a function of the temperature of the air entering the cylinders, characterized in that that the correction is of the multiplicative type: <IMAGE> with: - α air: richness correction term as a function of the air temperature T 'actually entering the cylinders; - T: air temperature measured by the injection computer; - T water: engine water temperature.
