- 摘要：
An engine (1) is provided with an SCR catalyst (41) that purifies NOx, a urea injection valve (230) that adds aqueous urea solution to the SCR catalyst (41), and a first NOx sensor (130) that detects the amount of generated NOx. A control unit (80) adds up the amount of generated NOx from when aqueous urea solution was previously injected, and performs an addition process for causing the urea injection valve (230) to inject aqueous urea solution after the integrated value becomes greater than or equal to a reference value.
