Abstract:
A fuel injection control device is applied to an internal combustion engine that includes a port injection valve and a direct injection valve. The fuel injection control device includes a port warm-up judgment section, which judges whether the intake port has been warmed up, and an injection mode determination section, which determines the injection mode based on the engine speed and a predicted load rate. When determining the injection mode at the cold operation of the internal combustion engine, the injection mode determination section sets the range of the operation region of the internal combustion engine in which the direct-injection-only mode is selected as the injection mode to be broader in a case in which the port warm-up judgment section has judged that the port has not been warmed up than in a case in which the port warm-up judgment section has judged that the port has been warmed up.

Claim (Index 4):
A fuel injection control method applied to an internal combustion engine including two types of injection valves including a port injection valve, which injects fuel into an intake port, and a direct injection valve, which injects fuel into a cylinder, wherein\n the fuel injection control method includes switching an injection mode between a port-injection-only mode, in which only the port injection valve of the two types of injection valves performs fuel injection, and a direct-injection-only mode, in which only the direct injection valve of the two types of injection valves performs fuel injection, and a state in which a wall temperature of the intake port is higher than or equal to a predetermined wall temperature is defined as a state in which the port has been warmed up, the fuel injection control method comprising: judging whether the port has been warmed up; determining the injection mode to be executed by the internal combustion engine based on an engine speed and an engine load; and when determining the injection mode in a cold operation, in which a coolant temperature of the internal combustion engine is lower than or equal to a predetermined coolant temperature, setting, in an operation region of the internal combustion engine specified by the engine speed and the engine load, a range of the operation region in which the direct-injection-only mode is selected as the injection mode to be broader in a case in which it is judged that the port has not been warmed up than in a case in which it is judged that the port has been warmed up.
