Title:
COMPRESSIVE IGNITION TYPE INTERNAL COMBUSTION ENGINE
Document Type and Number:
Japanese Patent JP3218867
Kind Code:
B2
Abstract:
PURPOSE: To provide a compressive ignition type internal combustion engine which uses a high compression ratio and makes ignition of a premixed gas by the compressive igniting or multi-point igniting process.
CONSTITUTION: The gasoline injection timing at the suction port 6 of a fuel injection valve 9 is put in the range between the crank angle 10deg. before closing of a suction valve 7 and 110deg. before its being opened, and the gasoline injection timing to a recess 3 in a fuel injection valve 11 is put in the range between the crank angles 8deg. and 30deg. before the compressive upper dead point, and the fuel injection amount is made between 15% and 25% of the total load injection amount (sum of the injection amount to the suction port and the injection amount to the recess). Thereby the compressive igniting of the completely premixed gas can be generated in good performance under a high compression ratio, and an ultra-lean combustion be accomplished and the performance in various items be enhanced.
