Abstract
In an internal combustion engine where an in-cylinder injector and an intake manifold injector can both be used, initial setting of a fuel injection ratio (DI ratio) in accordance with a condition of the engine is basically carried out in response to power-up of an engine ECU. Further, it is sensed that an engine start request is made after a prescribed period has elapsed since the power-up. In such a case, an initial setting value of the fuel injection ratio is updated in accordance with the condition of the engine at that time point. Thus, the fuel injection ratio between both injectors can appropriately be set in starting the engine, so that the engine is smoothly started.
