    摘要： There is provided a combustion control system for a direct-injection spark-ignition internal combustion engine, including a fuel injection valve that injects fuel directly into a cylinder of the engine to form an air-fuel mixture in a combustion chamber of the engine cylinder, a spark plug that ignites the air-fuel mixture, and a control unit that performs combustion retard control to set an ignition timing of the spark plug at a point after compression top dead center and set an injection period of the fuel injection valve at a time after compression top dead center and before the ignition timing in such a manner that a time interval from a start point of the injection period to the ignition timing increases with decrease in a temperature in the engine cylinder at a cold start of the engine.

    摘要： An internal combustion engine includes an intake port leading to an engine cylinder. The intake port is divided into first and second passage section by a partition extending in the intake port in a longitudinal direction of the intake port. A gas motion control valve is arranged to open and close an upstream end of the second passage section. A connection passage connects an upstream end portion of the second passage section to the first passage section. A fuel injector is directed to inject fuel toward a valve opening of the intake valve through a space on the downstream side of the downstream end of the partition.

    摘要： An intake apparatus for an internal combustion engine, including a partition dividing an intake port into a first passage and a second passage, and a gas motion control valve including a rotatable valve element disposed upstream of the partition and spaced from an upstream end thereof. The gas motion control valve has a full-closed position where the valve element prevents intake air from flowing into the second passage and a full-open position where the valve element allows the intake air to flow into the second passage. The valve element is inclined so as to guide a flow of the intake air to the first passage when the gas motion control valve is in the full-closed position. The valve element and the partition cooperate with each other to define an interspace therebetween when the gas motion control valve is in the full-closed position.
