CONTROL DEVICE FOR ENGINE EQUIPPED WITH SUPERCHARGER

An object of the present invention is to calculate an estimated value of an amount of air blowing through an inside of a cylinder by scavenging that occurs in an engine equipped with a supercharger, that is, a scavenging amount. For this purpose, a control device of an engine equipped with a supercharger according to the present invention calculates an estimated value of an intake valve passing air amount from a measured value of an intake air amount, and calculates an estimated value of an in-cylinder air amount from a measured value or an estimated value of intake pipe pressure. From a difference between the estimated value of the intake valve passing air amount and the estimated value of the in-cylinder air amount, the estimated value of the scavenging amount is calculated.
