ABSTRACT:
An engine C/U51detects an abnormality which has occurred in an engine, and outputs a signal that indicates the occurrence of this abnormality to an SCR-C/U61. The SCR-C/U61increases and decreases the urea water injection quantity corresponding to the abnormality which has occurred. On the other hand, the SCR-CU61detects an abnormality that has occurred in the SCR device, and outputs a signal that indicates the occurrence of this abnormality to an engine C/U51. The engine C/U51controls an engine part such as an EGR valve, to reduce the NOx emission amount.
