Abstract
An engine ECU executes a program including the step of detecting an engine coolant temperature (THW), the step of selecting a map for a warm state as the map for calculating a fuel injection ratio (or a DI ratio) (r) when the engine coolant temperature (THW) is equal to or higher than a temperature threshold value (THW(TH)), the step of selecting a map for a cold state as the map for calculating the fuel injection ratio (or the DI ratio) (r) when the engine coolant temperature (THW) is lower than the temperature threshold value (THW(TH)), and the step of calculating the fuel injection ratio between the in-cylinder injector and the-intake manifold injector (or the DI ratio) (r) based on the engine speed, load factor, and the selected map.
