Abstract

A device for determining air entering cylinders of an internal combustion engine having a supercharger. The air is determined as a function of such quantities as rpm, air throughput in the intake manifold, throttle valve position values and temperature, characterized in that at least the following physical relationships are included in the determination:suction equation of the enginebalancing equation for a filling in an intake manifoldflow rate equation at a throttle valvebalancing equation in a volume between the throttle valve and the supercharger.
