CONTROL APPARATUS FOR INTERNAL COMBUSTION ENGINE

摘要

An engine ECU executes a program including the step (S100) of detecting an engine coolant temperature (THW), the step (S120) 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)) (YES in S110), the step (S130) 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)) (NO in S110), and the step (S140) 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.
