摘要： A discriminating apparatus of liquid reducing agent is disclosed, in which, based on concentration of liquid reducing agent which is measured at each predetermined time after starting of engine, discrimination is processed whether the storage tank is filled with dissimilar aqueous solution, the storage tank is normally filled with the liquid reducing agent, or the storage tank is empty. When the empty discrimination or the dissimilar aqueous solution discrimination is performed, it is judged whether or not the discrimination is adequate according to the liquid condition in the storage tank. When the empty or the dissimilar aqueous solution discrimination is adequate, the empty discrimination frequency or the dissimilar aqueous solution discrimination frequency is counted up. When the empty discrimination frequency and the dissimilar aqueous solution discrimination frequency become equal to or larger than the first predetermined frequency, the discrimination is upheld.

摘要： The present invention is directed to defrost a reducing agent with cooling water of an engine and to prevent water scale from being deposited and accumulated on a cooling water pipe for circulating the cooling water. A frozen reducing agent is defrosted by being heated with cooling water of an engine. A cooling water pipe for guiding the cooling water to a reducing agent tank is provided with a cutoff valve. To defrost the reducing agent, the cutoff valve is opened. Even in the case where the reducing agent is not frozen, the cutoff valve is opened for a predetermined period after start of the cutoff valve to circulate the cooling water in the cooling water pipe.

摘要： An engine C/U 51 detects an abnormality which has occurred in an engine, and outputs a signal that indicates the occurrence of this abnormality to an SCR-C/U 61. The SCR-C/U 61 increases and decreases the urea water injection quantity corresponding to the abnormality which has occurred. On the other hand, the SCR-CU 61 detects an abnormality that has occurred in the SCR device, and outputs a signal that indicates the occurrence of this abnormality to an engine C/U 51. The engine C/U 51 controls an engine part such as an EGR valve, to reduce the NOx emission amount.

摘要： A technology for purifying an exhaust emission from an engine is provided, in which a misjudgment caused by a time lag between the abnormality detection and an abnormality judgment is avoided, in the case where a plurality of abnormalities is judged on the aqueous solution of a reducing agent or the like. After a first abnormality judgment (Femp=1: the time t2) is made, when a second abnormality is detected as a result that the concentration Dn as a state parameter is directly shifted from a first region A to a second region C (the time t3), the first abnormality judgment is maintained for a predetermined period of time PRD after the second abnormality detection.
