Abstract

The method involves taking a value of pressure in a combustion chamber (3) of a cylinder (1) of an engine, based on an angular position of a crankshaft (5), at an instant of an engine cycle close to an instant of closing of an inlet valve (6a) of the cylinder. A ratio between a value (p col) of a pressure to be obtained and the value (p cyl rfa) of the taken pressure is modeled. The pressure in an intake manifold (6) is calculated for each taken value. The value of the pressure to be obtained and taken pressure value are related by an equation P col=Axp cyl rfa +>B, where A, B are constants. An independent claim is also included for a device for estimating pressure in an intake manifold.
