PROCEDE ET DISPOSITIF D'AJUSTEMENT D'UN PARAMETRE DE COMBUSTION D'UN MOTEUR, SUPPORT D'ENREGISTREMENT POUR CE PROCEDE ET VEHICULE EQUIPE DE CE DISPOSITIF.

摘要

The invention relates to a method for adjusting a combustion parameter Pi of a combustion engine during a cold start, characterized in that the value of the parameter Pi is established (104) by interpolating between two predetermined values PiREF1 and PiREF2 as a function of the value ω of engine speed and of a temperature of an engine coolant, the values PiREF1 and PiREF2 being optimal in order to reduce pollutant emissions when the engine is running on reference fuel of respectively high volatility and low volatility.
