<P>PROBLEM TO BE SOLVED: To improve exhaust emission and drivability at acceleration in an internal combustion engine including an in-cylinder fuel injection valve and a supercharger. <P>SOLUTION: The internal combustion engine with the supercharger includes: the in-cylinder fuel injection valve for directly injecting fuel into a combustor chamber; an injection valve for an intake passage, the valve for injecting the fuel into the intake passage; and the supercharger for supercharging air suctioned into the combustion chamber. While an actual boost pressure rises to a target boost pressure at acceleration, uniformity of fuel-air mixture is enhanced to improve the efficiency of using air, by just performing fuel injection from an injector 2b for a port injection. As a result of the fuel injection control, smoke generation can be suppressed at acceleration and the exhaust emission can be improved. <P>COPYRIGHT: (C)2012,JPO&INPIT |
