<P>PROBLEM TO BE SOLVED: To provide method of controlling fuel injection for an engine equipped with an exhaust gas purifying system which is capable of intending to reduce occurrence of smoke without stopping rich condition, even if the rich condition and acceleration are overlapped when generating the rich condition in order to restore capability of NOx absorptive storage of NOx absorptive storage reduction type catalyst, and which can restrain fuel from deteriorating consumption. <P>SOLUTION: In the method of controlling fuel injection for the engine, the engine is equipped with the exhaust gas purifying system including the NOx absorptive storage reduction type catalyst in an exhaust passage of the engine. Main injection timing is retarded in the fuel injection only at acceleration when engine operation condition is set up the rich condition to reproduce the NOx absorptive storage reduction type catalyst. <P>COPYRIGHT: (C)2004,JPO&NCIPI |
