A control device of a diesel engine is provided. The diesel engine includes an injector for injecting fuel into a cylinder, and a turbocharger for compressing intake air by using exhaust energy. The control device includes a calculating module for setting a basic injection timing determined according to an operating state of the engine, as a timing of injecting the fuel from the injector, and an injection control module for injecting the fuel from the injector at the set basic injection timing at least while the engine is in a steady operation.

Control device of diesel engine with turbocharger

A glowplug control device for controlling an applied voltage or power for a glowplug is provided, which includes a target calculating module for calculating a target applied voltage or power to adjust a glowplug temperature to a predetermined target temperature, an output module for applying the target applied voltage or power to the glowplug when the target applied voltage or power is below a maximum applicable voltage or power, and applying the maximum applicable voltage or power to the glowplug when the target applied voltage or power is above the maximum applicable voltage or power, and a temperature estimating module for estimating the glowplug temperature to be the target temperature when the target applied voltage or power is applied to the glowplug, and estimating the glowplug temperature to be below the target temperature by a temperature decrease amount when the maximum applicable voltage or power is applied to the glowplug.
