Abstract: |
The invention is a forming method for hierarchical mixed gas in gasoline direct injecting engine, which relates to a hierarchical thin combustion method in the electric controlled gasoline direct injecting engine when with small and middle load. The invention uses the multi-section gasoline spraying as the primary means, it carries on gasoline ejection with two times or three times, it carries on the first ejection in the induction stroke, carries on the second or the second and the third ejections in the compression stroke; the shape of the combustion room on top of the piston uses the simple and regular shallow round combustion room; at the same time, the normal turbine induction method is reserved. The invention can reduce the design difficulty of the combustion room; it can control the range and intensity of the combustible mixed gas density easily. |
