摘要:
Provided is an exhaust-treatment device for a diesel engine, said device being capable of suppressing engine noise. In a first stage P1 of an exhaust-temperature-raising process, a target engine speed is set to a prescribed first target speed R1 and an intake throttle valve 41 is set to a prescribed first degree of opening O1. In a second stage P2, the target engine speed is maintained at the first target speed R1 and the intake throttle valve 41 is set to a position more closed than the first degree of opening O1. When a set duration T2 for the second stage P2 has come to an end, the intake throttle valve 41 is at a second degree of opening O2, which is maintained in third and subsequent stages P3/P4. In said third and subsequent stages P3/P4, as a set duration T3/T4 for each stage P3/P4 passes, the target engine speed is updated to a target speed R2/R3 higher than the target speed R1/R2 during the immediately prior stage P2/P3, and the temperature of DPF1 upstream exhaust gas 12 is increased.

摘要:
The disclosed exhaust treatment device for a diesel engine can prevent heat damage to a DPF when regenerating said DPF. If a selection device (7), which selects whether to allow or prohibit an automatic DPF regeneration process, is set to prohibit the automatic DPF regeneration process, a DPF regeneration control device (4) is made able to start a process to cancel execution of the automatic DPF regeneration process. If the selection device (7) is set to allow the automatic DPF regeneration process, the DPF regeneration control device (4) retracts the cancellation of the automatic DPF regeneration process, allowing execution of the previously-cancelled automatic DPF regeneration process to begin.
摘要:
An object of the present invention is to provide the exhaust treatment device of a diesel engine which is capable of prohibiting the execution of DPF regenerating processing in a situation in which the DPF regenerating processing is inappropriate. In order to achieve the object, DPF regenerating mode switch manipulation means (7a) switches a DPF regenerating mode to a normal and acceleration coexistence regenerating mode (51) or an acceleration-sole regenerating mode (52), and DPF regenerating selection manipulation means (7b) switches a position to a normal regenerating permission position (53), a normal regenerating cancel position (54), or an acceleration regenerating execution position (55). When the DPF regenerating mode is in the acceleration-sole regenerating mode (52), the DPF regenerating control means prohibits normal regenerating processing by the DPF regenerating means irrespective of a position selected by the DPF regenerating selection manipulation means (7b).

A mounting structure includes an electronic component mounted on a circuit board. Land electrodes are disposed on a board body and are connected to outer electrodes of the electronic component through solders, respectively. A distance from each of the land electrodes to a top of the corresponding solder is not larger than about 1.27 times a distance from each of the land electrodes to an exposed portion of a capacitor conductor exposed at an end surface of the electronic component, the capacitor conductor being positioned closest to the circuit board.
