Abstract: A current path to a gate is cut off by a normally-off first switch element until start-up of a gate drive voltage generator is sensed. Furthermore, a semiconductor switching element is maintained in an off state as a normally-on second switch element short-circuits the gate to a source. As start-up of the gate drive voltage generator is sensed, the second switch element is turned off and the first switch element is turned on. As the gate is thus driven by an output from a signal amplifier in accordance with a control signal, the semiconductor switching element is turned on and off in accordance with the control signal.

Abstract: Provided is a diesel engine capable of regenerating a DPF even during no-load and/or light-load operation. In a DPF regeneration process, opening-degree reduction control S2 for an exhaust-air throttle valve is performed after a start condition S1 of the regeneration process of the DPF in which PM is deposited is satisfied. When exhaust air reaches a temperature equal to or higher than a predetermined after-injection permissible temperature TA, after-injection control is subsequently started S5. Post-injection control is started S7 after the exhaust air reaches a temperature equal to or higher than a predetermined post-injection permissible temperature TP by combustion of after-injection fuel. The PM deposited in the DPF is incinerated by the exhaust air increased in temperature by catalytic combustion of post-injection fuel in a valve downstream-side DOC.
