<P>PROBLEM TO BE SOLVED: To provide an internal combustion engine controller, wherein, in an internal combustion engine including a supercharger, a pre-ignition is well suppressed regardless of whether blow-by of a gas from an intake passage side toward en exhaust passage side via a combustion chamber is generated. <P>SOLUTION: The internal combustion engine controller includes: a turbo supercharger having a compressor 26 supercharging intake air; and an in-cylinder fuel injection valve 34 supplying fuel in the cylinder of an internal combustion engine 10. When a pre-ignition is detected, a pre-injection as an fuel injection for suppressing the pre-ignition is executed by using the in-cylinder fuel injection valve 34, in advance of a main injection for generating a torque of the internal combustion engine 10. In this constitution, according to whether the blow-by of the gas from the intake passage 16 side toward the exhaust passage 18 side via the combustion chamber 14 is generated, the execution time of the pre-injection is controlled. <P>COPYRIGHT: (C)2012,JPO&INPIT |
