METHOD AND ESTIMATOR OF FRESH AIR MASS IN A COMBUSTION CHAMBER, TOTAL FILLING ESTIMATING METHOD, RECORDING MEDIUM FOR THESE METHODS AND VEHICLE EQUIPPED WITH SAID ESTIMATOR

摘要

The invention relates to a method for estimating the mass Ma of fresh air admitted inside a combustion chamber of a cylinder of an engine during an engine cycle, characterized in that this method comprises estimating (128) a total mass Mtot of gas contained in the combustion chamber at the end of the intake of fresh air, the estimate (120, 124) of a mass Mb of burnt gas contained in the combustion chamber at the end of the flue gas exhaust, and the estimate (128) of the mass Ma of fresh air from the difference between the total mass Mtot and the estimated mass Mb of flue gases.
