Abstract
An engine includes an injector, an ignition plug, a supercharger, an electronic throttle device, and an EGR apparatus. An EGR passage has an inlet connected to an exhaust passage downstream of a turbine and an outlet connected to the intake passage upstream from a compressor. A fresh-air introduction passage is arranged to introduce fresh air to a surge tank downstream from the electronic throttle device and a fresh-air control valve is provided to regulate a fresh air amount. When an ECU determines that the engine is under deceleration and under fuel supply, the ECU closes the electronic throttle device to a predetermined opening degree to scavenge EGR gas flowing from the EGR passage and remaining in the intake passage, opens a fresh-air control valve to a predetermined opening degree, and causes the ignition plug to retard an ignition timing.
