A control apparatus for a diesel engine includes a neighboring temperature estimating section which estimates a temperature of a neighborhood of a glow plug that heats an interior of a cylinder upon startup, and a supercharging pressure control section which controls a supercharging pressure in such a way that a rotation fluctuation of the engine does not increase, on the basis of the estimated temperature of the neighborhood of the glow plug.

Control apparatus and control method for diesel engine

An engine fuel injection control apparatus has a parameter setting section, a parameter changing section and a determining section. The parameter setting section is configured to set a parameter of fuel injected into an engine to a first injection parameter to control a state of combustion noise or exhaust emission to a target state when an engine operation condition is in a first operation region. The parameter changing section is configured to change the parameter of fuel injected into the engine from the first injection parameter to a second injection parameter when the engine operation condition remains in the first operation region. The determining section is configured to determine whether or not an actual state of the combustion noise or the exhaust emission of the engine changes when the parameter of fuel injected into the engine is changed from the first injection parameter to the second injection parameter.
