摘要：A method for purging a catalyst containing oxidants operates the engine atdifferent air-fuel ratios during different intervals. The intervals are adaptively adjusted
based on a model that predicts an amount of fuel needed to perform the purging. Theintervals are also responsive to an exhaust gas sensor located downstream of thecatalyst.
