Abstract
A stratified charge burning internal combustion engine with a fuel injection time controlling function wherein production of smoke upon high load operation of the engine can be reduced by control of the fuel injection time. Fuel injection time setting means sets a fuel injection end time and further sets a fuel injection start time from the fuel injection end time and a required fuel amount, and injector driving means drives an injector in accordance with the fuel injection times. Consequently, air fuel mixture and air from a pair of intake ports are flowed into the combustion chamber to make laminar tumble swirls so as to effect laminar combustion. Then, if judging means judges that the engine is operating but not in the proximity of the full load operation, then partial load time setting means sets a partial-load-time fuel injection end time, but if the judging means judges opposite, then full load time setting means sets a partial-load-time fuel injection end time to a predetermined time after starting of an intake stroke so as to reduce production of smoke.
