Fuel injection type internal combustion engine

An internal combustion engine having a combustion chamber, comprising:

• a first intake valve opening at a crank angle near to top dead center of an intake stroke and closing at a beginning of a compression stroke;
• a second intake valve opening at a crank angle near to the top dead center of the intake stroke and closing at the beginning of the compression stroke;
• a third intake valve opening approximately at the center of the intake stroke and closing at the beginning of the compression stroke;
• a first intake passage connected to said combustion chamber via said first intake valve and creating a swirl motion in said combustion chamber;
• a second intake passage connected to said combustion chamber via said second intake valve;
• a third intake passage connected to said combustion chamber via said third intake valve;
• an air control valve arranged in said second intake passage;
• means for actuating said air control valve in response to an engine load to open said air control valve when the engine load exceeds a predetermined load;
• a fuel injector arranged in said third intake passage;
• and
• electronic control means controlling a fuel injecting operation of said fuel injector to stop the fuel injecting operation during the intake stroke.
