摘要 |
An engine where first combustion where the amount of the EGR gas in the combustion chamber is larger than the amount of EGR where the amount of production of soot peaks and a second combustion where the amount of EGR gas in the combustion chamber is smaller than the amount of EGR gas where the amount of production of soot peaks are selectively switched between and where an NOx absorbent is placed in the exhaust passage of the engine. When SOx should be released from the NOx absorbent, the first combustion is performed under a rich air-fuel ratio, while when the second combustion is performed, auxiliary fuel is injected during the first part of the suction stroke or the expansion stroke and the injection timing of the main fuel is delayed by a large extent. <IMAGE> |
