摘要:
An internal combustion engine comprises a variable valve control device that varies a lift degree of an intake valve, an air intake passage led to an intake port of the engine that is incorporated with the intake valve and a fuel injection valve arranged to inject fuel into the intake port. The fuel injection valve has a first injection mode wherein each fuel injection shot is entirely carried out during opening period of the intake valve and a second injection mode wherein each fuel injection shot entirely finishes prior to opening action of the intake valve. A control unit is further employed by the engine, which allows the fuel injection valve to select one of the first and second injection modes in accordance with the lift degree of intake valve effected by the variable valve control device.
