Abstract

A fuel injection control device (27) injects fuel for learning into a combustion chamber (4) of an engine (1) from a nozzle (7) of a fuel injection valve (5), to perform learning of injection quantity of the fuel injection valve (5). The fuel injection control device (27) is provided with an exposed heat temperature detection means (28, 31) for detecting an exposed heat temperature of the nozzle (7), an exposed heat amount acquisition means (31) for acquiring an exposed heat amount of the nozzle (7), based on the exposed heat temperature of the nozzle (7) detected by the exposed heat temperature detection means (28, 31) and an operating time of the engine (1), and a learning interval change means (31) for changing an interval of execution of the injection quantity learning, according to the exposed heat amount of the nozzle (7) acquired by the exposed heat amount acquisition means (31).
