Abstract

A control device of a diesel engine with a turbocharger is provided. The device includes an engine body having a cylinder, a fuel injection valve, a turbine of the turbocharger, a bypass passage for bypassing the turbine, a bypass valve for opening and closing the bypass passage, an oxidation catalyst for purifying HC, and a DPF for capturing soot. The device includes a fuel cutting module for stopping, when the diesel engine is in a deceleration state, a main injection of the fuel performed on compression stroke, a DPF regenerating module for performing, when a predetermined DPF regeneration condition is satisfied, a post injection on expansion stroke to supply HC to the oxidation catalyst and regenerate the DPF by heat generated from an oxidation reaction of HC, and a bypass valve control module for controlling the bypass valve.
