摘要： A straight port and a swirl port supply low-oxygen-concentration gas and high-oxygen-concentration gas into a combustion chamber of an engine such that high-level-oxygen-concentration gas and low-level-oxygen-concentration gas are formed from the high-oxygen-concentration gas and the low-oxygen-concentration gas in an adjacent region of the combustion chamber, which is adjacent to a fuel mist injected from an injection hole of a fuel injection valve. The high-level-oxygen-concentration gas is located in a corresponding area of the adjacent region, which is generally opposite from the fuel injection hole, and the low-level-oxygen-concentration gas is located in a remaining area of the adjacent region, which is other than the corresponding area of the adjacent region.
