Abstract
A fuel injection control device of a diesel engine is provided. The device includes an engine body to be supplied with fuel mainly containing diesel fuel, a fuel injection valve for injecting the fuel into a cylinder of the engine body, a fuel injection control module for controlling the fuel injection by the fuel injection valve, and a catalyst for purifying HC provided in an exhaust passage through which exhaust gas is discharged from the cylinder. When the catalyst is in a deactivated state or the engine body is in a cold state, the fuel injection control module controls the fuel injection valve to perform a main injection for generating in the cylinder a main combustion mainly including a diffusion combustion, and a pre-injection for injecting the fuel before the main injection to generate a pre-combustion in the cylinder before the main combustion.
