<P>PROBLEM TO BE SOLVED: To ensure the consistent combustion when executing the combustion in the low air-fuel ratio combustion mode in a compression ignition type internal combustion engine. <P>SOLUTION: When executing the combustion in the low air-fuel ratio combustion mode, if the actual intake air amount is larger than the target value, the increase in the main injection which is necessary for controlling the main combustion air-fuel ratio which is the ratio of the intake air amount to the fuel injection by the main fuel injection to a target value is calculated. If the increase in the calculated main injection is equal to or less than the prescribed value, the main injection is increased by the increased amount. If the increase is larger than the prescribed value, the sub fuel injection timing is subjected to the angle of lead. <P>COPYRIGHT: (C)2012,JPO&INPIT |
