摘要： A partitioning wall is provided in a fluid space formed between a cover member and a body member, which surrounds a forward end of a fluid injection valve. The partitioning wall divides the fluid space into an inlet-side fluid space and an outlet-side fluid space in a circumferential direction of the fluid injection valve. A forward-end space, which is formed at a bottom of the fluid space, is communicated to the inlet-side and the outlet-side fluid spaces, so that cooling water flows from the inlet-side fluid space to the outlet-side fluid space through the forward-end space. The cooling water circulates in the forward-end space surrounding the forward end of the fluid injection valve to effectively cool down the fluid injection valve.

摘要： An object is to prevent abrasion inside an addition valve and clogging of the addition valve due to an increase in the particle diameter of precipitates. A first control is performed by which a pump is caused to operate in such a way as to return urea solution contained in the addition valve and a urea solution channel to a tank by a predetermined quantity. After the lapse of a certain time after the end of the first control, a second control is performed by which the pump is caused to operate in such a way as to return the urea solution remaining in the addition valve and the urea solution channel thoroughly to the tank.

摘要： A cooling time computing unit computes, based on a temperature detected by a temperature detection unit, a cooling time during which an injection unit is cooled by driving of an engine. A notification control unit uses a notification unit to notify an operator of a necessity of cooling before the engine is stopped, during the cooling time computed by the cooling time computing unit.
