摘要:
[Objective] To suppress torque variation, etc. when a diesel engine is switched to premixed combustion. [Means for Solution] Wen the diesel engine is switched to premixed combustion in a state in which EGR is being performed, the interior of a cylinder of the diesel engine is heated by a cylinder heater. Also, at least fuel injection timing control for the diesel engine is performed.

An electric current supply control apparatus for a glow plug, and glow plug and the electric current supply control apparatus connected to the glow plug. In a transition state in which the load acting on an engine increases such as at the time of acceleration (S 14: YES), an instruction signal which instructs increasing of an EGR amount is transmitted to an ECU (S18). Further, electric current is supplied to a heat generation resistor of a glow plug through resistance PI control (S20), whereby the temperature of the heat generation resistor is stably maintained at a target temperature, and stability of combustion is enhanced. Thus, even at the time of acceleration, generation of NO x can be suppressed effectively by increasing the EGR amount without lowering the engine output.

摘要:
To decrease combustion noise, etc. of a diesel engine(10) at the time of transition to premixed combustion, the cylinder pressure of the diesel engine (10) is detected, and a parameter which is related to change in the cylinder pressure of the diesel engine is computed on the basis of the detected cylinder pressure. The fuel injection timing at the time when combustion in the diesel engine is switched to premixed combustion is controlled such that the parameter falls within a target range.
