Reducing agent injection device and control method thereof |
| abstract |
A reducing agent injection device capable of eliminating clogging of a reducing agent injection valve caused by solidification of an aqueous urea solution and suppressing a decrease in exhaust purification efficiency. Reduction in which an aqueous urea solution is supplied into an exhaust pipe through a reducing agent injection valve fixed to the exhaust pipe, and the aqueous urea solution in the reducing agent injection valve is recovered in a storage tank when the internal combustion engine is stopped. The agent injection device includes a pressure feed pump that pumps the urea aqueous solution and a reducing agent supply passage that connects the pressure feed pump and the reducing agent injection valve, and the reducing agent injection valve is clogged due to solidification of the urea aqueous solution. The pressure pulsation is generated in the reducing agent supply passage for a predetermined period (W1). [Selection] Figure 6 |
