Abstract (en)
[origin: WO9015236A1] In this process, the combustion air mass in the cylinders of an internal combustion engine is determined by measuring the air mass and the pressure in the combustion chamber. The combustion air mass determined by measuring the pressure in the combustion chamber is compared with the combustion air mass determined by measuring the air mass, and is used to correct the results of the latter measurement.
