Abstract: In a stratification operation, O2 is injected from an oxygen injector during valve opening of an intake valve. Therefore, the injected O2 flows into a combustion chamber immediately after the injection, and forms a layer having a constant spread in the combustion chamber. Meanwhile, the working gas in the combustion chamber forms such a layer as to cover the O2 layer on a wall surface of the combustion chamber in conjunction with formation of the O2 layer. In other words, in the combustion chamber, an inner layer with a high O2 concentration and an outer layer with a high working gas concentration are respectively formed.
