摘要： PROBLEM TO BE SOLVED: To surely reduce and purify NO x even during constant speed or accelerating operation under intermediate or high load in which an accelerator off state hardly occurs in an exhaust emission control device in which a three-way catalyst having NO x and NH 3 adsorbing property is applied to a diesel engine, NH 3 is generated from NO x in the accelerator off state during the operation of the engine and adsorbed and stored by the three-way catalyst, and the NO x in the exhaust gas is reduced and purified using the NH 3 . SOLUTION: A fuel adding valve 15 (fuel adding means) is installed in an exhaust pipe 11 further on the upstream side than the three-way catalyst 14. A controller 20 is so formed that an excess air ratio is lowered less than in the accelerator off state during the operation of the engine during constant speed or accelerating operation under intermediate or high load under the state in which the NO x adsorbed amount of the three-way catalyst 14 exceeds an allowable amount, and fuel is supplementarily added to the intermediate part of the exhaust pipe 11 by the fuel adding valve 15 to lower the excess air ratio to near approximately 1.0 on the inlet side of the three-way catalyst 14.

摘要： PROBLEM TO BE SOLVED: To provide a simple and inexpensive exhaust gas treatment device having a selective reduction NOx catalyst device.
SOLUTION: A combustion burner 8, a particulate filter 4, a urea water adding device 5, a urea SCR catalyst device 6, and an ammonia oxidation catalyst device 7 are disposed in an exhaust passage 2 in this order. An HC trap catalyst device 10 is disposed between a filter 4 and the urea water adding device 5. The HC trap catalyst device 10 temporarily traps HC in the exhaust gas when an exhaust gas temperature is equal to or below a predetermined one. When the temperature exceeds the predetermined one, the catalyst device releases the trapped HC while oxidizing. When the filter 4 is regenerated by the combustion burner 8, therefore, the HC trap catalyst device 10 decreases the possibility that the urea SCR catalyst device 6 is poisoned by trapping unburned HC to suppress the lowering of an NOx reduction performance. The HC trap catalyst device 10 is a zeolite catalyst which is lower in price than an oxidation catalyst formed mainly of a precious metal such as platinum.

摘要： PROBLEM TO BE SOLVED: To provide a control device of an exhaust gas treatment device capable of suppressing consumption of a reducer, effectively reducing a specific component in exhaust gas, and purifying the exhaust gas even while having simple and inexpensive structure. SOLUTION: Unlike the prior art of injecting and adding urea water addition amount suitable for a NOx discharge amount discharged from an internal combustion engine 1 upon starting urea water addition, urea water is injected and added by increasing its amount from a state of urea water adding amount =0 by a first prescribed amount at every predetermined time (S1-S3), a detection signal of an ammonia sensor 8 is observed, when NH 3 flows out to an exhaust gas downstream side of a urea SCR catalyst 5, the urea water addition amount is decreased at every predetermined time (S1, S2, S4, S5), and when NH 3 stops flowing out to the exhaust gas downstream side of the urea SCR catalyst 5, the urea water addition amount at that time is maintained (S5, S6). Therefore, compared to the prior art, NOx in exhaust gas can be reduced and exhaust gas can be purified while suppressing the consumption amount of urea water. COPYRIGHT: (C)2009,JPO&INPIT
