ENGINE CONTROL DEVICE

摘要

Disclosed is an engine exhaust performance diagnosis/control device, in particular, a control device that reduces exhaust during starting, or diagnoses exhaust deterioration during engine starting. The amount of HC emission during engine starting is diagnosed. 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 aforementioned engine efficiency and the aforementioned level of engine combustion stability.
