Abstract
A fuel injection device includes a fuel injection valve for injecting fuel, which is distributed from a pressure-accumulation vessel. A pressure sensor is located in a fuel passage, which extends from the pressure-accumulation vessel to a nozzle hole. The pressure sensor is located closer to the nozzle hole than the pressure-accumulation vessel. A storage unit stores individual difference information obtained by an examination. The individual difference information indicates an injection characteristic of the fuel injection valve and indicates at least one of an injection response time delay between an injection start point and a time point, at which a fluctuation is caused by the start of fuel injection in detected pressure of the pressure sensor, and a parameter for calculating the injection response time delay.
