INTAKE AIR CONTROL METHOD FOR INTERNAL COMBUSTION ENGINE

摘要

The invention relates to a method for controlling a supply of air to an internal combustion engine (1) with which a motor vehicle is equipped. The engine (1) is equipped with an air supply pipe (5) provided with a regulating member (8) for regulating the flow rate of a flow (9) of air flowing along the air supply pipe (5). The method comprises a step of positioning the regulating member (8) which is able to move between a wide open position in which the regulating member (8) allows the flow of air (9) to pass and a closed position in which the regulating member (8) prevents such passage. The method comprises a step of calculating an air intake coefficient AADM in order to determine a position for the regulating member (8). The calculation step takes into consideration a variation in the acoustic tuning frequency f 0 of a column of air (14) housed within the air supply pipe (5).
