Patent ID: 6928983

Claim:
A controller for controlling fuel injection in an engine, the engine including an intake passage, a combustion chamber, a passage injector for injecting fuel into the intake passage, and an in-cylinder injector for injecting fuel into the combustion chamber, the controller comprising: a control means for controlling the passage injector and the in-cylinder injector so that the passage injector and the in-cylinder injector allocate and inject fuel; and a correction means for correcting the fuel injection amount for the engine with a correction value that is based on an air-fuel ratio in the engine, the correction means correcting a fuel injection amount of only one of the injectors among the passage injector and the in-cylinder injector with the correction value when the fuel injection amount of the other one of the injectors among the passage injector and the in-cylinder injector is less than or equal to a value that indicates the possibility of the fuel injection amount falling below an allowable lower limit value due to correction with the correction value.
