ABSTRACT:
An engine having a charger arranged in the intake passage, and a Karman vortex type air flow meter or a movable vane typed air flow meter also arranged in the intake passage, downstream of the charger. Further a pressure sensor and a temperature sensor are arranged in the intake passage downstream of the charger. The mass flow of air fed into an engine cylinder is calculated from the signals output by the air flow meter, the pressure sensor, and the temperature sensor.
