INTERNAL COMBUSTION ENGINE DEVICE, POWER OUTPUT DEVICE HAVING THE INTERNAL COMBUSTION ENGINE DEVICE, VEHICLE ON WHICH THE INTERNAL COMBUSTION ENGINE DEVICE IS MOUNTED, AND METHOD OF CONTROLLING THE INTERNAL COMBUSTION ENGINE DEVICE

摘要

PPROBLEM TO BE SOLVED: To properly operate an internal combustion engine by properly setting a target fuel injection amount to be injected for each cylinder of the engine. PSOLUTION: When a catalyst temperature c is higher than a threshold ref (S320), an increase factor Kf is so determined as to be more increased as the opening/closing timing of an intake valve is spark-advanced, a suction air amount Qa is more increased, or the rotational speed Ne of the engine 22 is more increased (S340). A target fuel injection amount Qf* is set according to the product of a basic fuel injection amount Qftmp set according to the suction air amount Qa by the increase factor Kf (S350). A fuel is injected at the set target fuel injection amount Qf*. PCOPYRIGHT: (C)2008,JPO&INPIT
