<P>PROBLEM TO BE SOLVED: To diagnose an amount of HC emission during engine starting in an engine exhaust performance diagnosis/control device, and in particular, a control device that diagnoses exhaust deterioration during engine starting or reduces exhaust during starting. <P>SOLUTION: The device is provided with a means for detecting engine efficiency and a means for detecting the level of engine combustion stability. The amount of HC emission until catalyst activation during engine starting is detected on the basis of the engine efficiency and the level of engine combustion stability. <P>COPYRIGHT: (C)2012,JPO&INPIT |
