Abstract
A fuel injection control device is configured to control fuel injection of an injector attached to a cylinder head of an internal combustion engine and coupled to a delivery pipe. The fuel injection control device includes processing circuitry configured to execute an injection duration calculation process of calculating an injection duration of the injector required for injection of a requested amount of fuel. The injection duration calculation process includes calculating the injection duration such that the injection duration is longer when a temperature difference between the cylinder head and the delivery pipe is a first value than when the temperature difference is a second value smaller than the first value.
