Abstract
Exhaust particulates are collected by a GPF(gasoline particulate filter) device. EGR control is executed, and exhaust gas flowing through an exhaust passage upstream of the GPF device is introduced into an intake passage via an EGR passage. In the EGR control, an opening area of the EGR passage is controlled to reduce the opening area of the EGR passage according to an operating state of the engine as a particulate deposition amount in the GPF device is increased.
