摘要：
Methods and systems are provided for improving purge air-fuel ratio control. Fuel vapors from a canister and the crankcase are selectively purged to a group of cylinders and not to remaining engine cylinders. Exhaust is recirculated from the selected group of cylinders to the engine intake wherefrom the EGR is ingested in the remaining engine cylinders and the selected group of cylinders.
