Abstract
A system for controlling fuel injection in an engine. The engine includes an intake passage, an intake passage injector, a cylinder having a combustion chamber, and a cylinder injector for injecting a target amount of fuel into the combustion chamber. The system includes a controller for controlling the intake passage and cylinder injectors to permit fuel injection, each with an injection ratio, while said engine operates in a condition in which said engine permits fuel injection from said cylinder injector, a sensor for sensing the amount of fuel injected from the cylinder injector, a detector for detecting the difference between the target injection amount and the amount of fuel injected and an adjuster for adjusting the injection ratio based on the result of the detection by the detector so that the intake passage injector performs fuel injection together with the fuel injection performed by the cylinder injector.
