Abstract
A low NOx combustion mode is executed in which the fuel injected timing IT is greatly advanced to 36° BTDC as compared with a normal value of roughly 10° BTDC. At this fuel injection timing IT, the smoke emission amount is suppressed below an extremely low value, even if the EGR ratio Regr is increased to about 56%, and the NOx emission amount is suppressed owing to a large amount of EGR, so that the smoke and NOx can be reduced at the same time.
