Abstract
A method for determining atmospheric pressure AMP during operation in a partial load state of a turbocharged engine () including an air intake line () incorporating a butterfly valve (), and an exhaust line () including a bypass duct () incorporating an exhaust gas discharge valve (), the method includes measuring the air pressure PUT upstream of the butterfly valve (), and for a given speed of N rpm of the engine (), when the boost pressure PUT corresponds substantially to the natural boost pressure, determining the atmospheric pressure AMP=AMP(0)+PUT−PUT(0), wherein AMP(0) is the atmospheric pressure previously measured, and PUT(0) is boost pressure naturally obtained for the speed N rpm of the engine () for the atmospheric pressure AMP(0).
