ABSTRACT:
In an evaporation fuel control system, a failure diagnosis monitor of the evaporation fuel control system in the limited stable operating state, such as an exhaust gas mode or the like, can be performed so that the failure state is early detected and discharge of hydrocarbon (HC) into the atmosphere due to a leakage of the evaporation fuel from the evaporation fuel control system is prevented.
