(57) [Summary] To determine the amount of air supplied to a cylinder of an internal combustion engine by using a supercharger depending on a rotation speed, a flow rate of air passing through an intake pipe, a throttle valve position adjustment value, and a temperature. In the device, at least the following physical associations:-the exhaust equation of the internal combustion engine,-the balance equation of the filling rate in the intake pipe,-the flow equation of the throttle valve,-the volume between the throttle valve and the supercharger. An apparatus for utilizing a balance equation when determining an air amount. |
