method of adjusting a combustion engine pi parameter of a combustion engine; means of recording information; adjustment device of at least one pi parameter of combustion of a combustion engine and vehicle

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 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.
