摘要：
A control system and method for controlling an engine includes a control module. The control module includes an evaporation control valve module closing a canister purge valve during a system diagnostic. A torque determination module determines a torque change for an end of the system diagnostic. A torque adjustment module changes an engine torque to a changed torque corresponding to the torque change. The evaporation control valve module opens the purge valve at the end of the diagnostic.
