摘要： A fuel injection control apparatus and method for an internal combustion engine are provided for appropriately controlling the amounts of fuel supplied from an in-cylinder fuel injection valve and a port fuel injection valve to a cylinder in a simple control approach while satisfactorily reflecting a fuel transport behavior as a whole cylinder. An ECU calculates a required in-cylinder injection amount and a required port injection amount, calculates an in-cylinder injected fuel behavior parameter of a fuel from the in-cylinder fuel injection valve and a port injected fuel behavior parameter of the fuel from the port fuel injection valve, a net in-cylinder injection amount in accordance with the in-cylinder and port injected fuel behavior parameters based on the required in-cylinder injection amount, and a net port injection amount in accordance with the in-cylinder and port injected fuel behavior parameters based on the required port injection amount.

摘要： A fuel injection control apparatus and method for an internal combustion engine are provided for appropriately calculating fuel injection times for an in-cylinder fuel injection valve and a port fuel injection valve, thereby accurately controlling the amounts of fuel supplied to the internal combustion engine from the in-cylinder fuel injection valve and the port fuel injection valve, respectively. The fuel injection control apparatus calculates an in-cylinder fuel injection amount which should be injected by the in-cylinder fuel injection valve, and calculates an in-cylinder fuel injection time which is a valve opening time of the in-cylinder fuel injection valve in accordance with the calculated in-cylinder fuel injection amount and an acquired cylinder internal pressure. The fuel injection control apparatus further calculates a port fuel injection amount which should be injected by the port fuel injection valve, and calculates a port fuel injection time which is a valve opening time of the port fuel injection valve in accordance with the calculated port fuel injection amount and a detected pressure within an intake system.

摘要： An internal EGR control system for an internal combustion engine, which is capable of controlling the internal EGR amount with accuracy, when controlling the internal EGR by changing both the exhaust cam phase and the exhaust valve lift. An internal EGR control system for an internal combustion engine controls internal EGR in which combustion gases are caused to remain in a cylinder. An ECU sets a target cam phase serving as a target of the exhaust cam phase, and controls a variable exhaust cam phase mechanism such that the exhaust cam phase becomes equal to the target cam phase. ECU 2 sets a target lift of an exhaust valve according to a detected actual cam phase and calculated valve-closing timing, and controls a variable exhaust valve lift mechanism such that the lift of the exhaust valve becomes equal to the target lift.
