摘要：
An air-fuel ratio of respective (individual) cylinders of an engine is changed individually from a stoichiometric air-fuel ratio to a lean air-fuel ratio with the change timing of each of respective cylinders deviated and the intake air flow into an engine 11 is changed gradually by opening an air bypass valve in parallel to the changing of the air-fuel ratio. Concurrent change of ignition timing is also disclosed.
