摘要： An electronic control unit corrects ignition timing according to changes in an internal EGR amount accompanying actuation of a variable valve actuation mechanism used in an internal combustion engine. The electronic control unit computes a base correction amount AWTb based on an engine speed NE and an engine load ratio KL. The control unit multiplies the base correction amount AWTb by the ratio of a square number of an actual valve overlap amount realOL to a square number of a target valve overlap amount tOL, thereby computing a VVT correction amount AVVT of ignition timing. As result, the engine is easily and properly controlled based on the relationship between the state of the variable valve actuation mechanism and changes in the internal EGR amount.

摘要： An electronic control unit of an internal combustion engine computes a remaining combusted gas amount M egr1 , which exists in a cylinder immediately before an intake valve is opened, based on an intake pipe pressure Pm, an engine speed NE, and an intake valve opening timing T open . At the same time, the control unit computes a backflow combusted gas amount M egr2 , which is the amount of combusted gas that flows back into the cylinder from an exhaust pipe after the intake valve is opened, based on the intake pipe pressure Pm, the engine speed NE and a valve overlap amount OL. The control unit computes the sum of the remaining combusted gas amount M egr1 and the backflow combusted gas amount M egr2 , and sets the sum as an estimated internal EGR amount M egrALL . As a result, the internal EGR amount is readily and accurately estimated.
