The method is of the type in which the air filling (R_CYL) of the internal combustion engine (MT) is estimated by means of an acoustic coefficient (CA) applied to a gas pressure (PR) in an air intake distributor of the engine. According to the invention, the method includes controlling the evolution of the acoustic coefficient in a transitional zone between an atmospheric zone and a supercharged zone according to a law that takes into account an opening position (PP) of a throttle body (PD) of the internal combustion engine.

An object of the present invention is to provide an exhaust gas purification catalyst filter that improves soot capture performance without increasing the pressure loss associated with forming a catalyst layer within the partition walls of a wall-flow type substrate. The exhaust gas purification catalyst filter for gasoline engines purifies exhaust gas from gasoline engines and is formed of a wall-flow type substrate and a catalyst layer. The wall-flow type substrate is defined by porous partition walls to define an inlet-side cavity open at the exhaust gas inlet side and an outlet-side cavity adjacent to the inlet-side cavity and open at the exhaust gas outlet side. The catalyst layer is formed within the pores of the partition walls. The absolute value of the partiality of the catalyst layer formed within the pores of the partition walls is 4.50 or less. The amount of the washcoat layer, excluding the mass of the platinum group, formed within the pores of the partition walls is 40 g / L or more and 50 g / L or less. The catalyst layer formed within the pores of the partition walls is a single layer and does not contain Ba.
