Abstract:

PROBLEM TO BE SOLVED: To increase the amount of non-burnt HC discharged from an engine when necessary.
SOLUTION: An internal combustion engine is provided with a fuel injection valve 6 for injecting fuel into a combustion chamber 5 and valve overlapping period control actuators 47 and 48 for controlling a valve overlapping period when an intake valve 7 and an exhaust valve 9 are simultaneously opened. When the necessity of increasing the amount of non-burnt hydrocarbons discharged from the engine is determined, the valve overlapping period is extended, and at least a part of fuel is injected during the valve overlapping period.
