摘要： A method and system for reducing time required for a catalyst to reach optimum operating temperature control an air/fuel ratio based on the catalyst temperature to supply excess air to the catalyst during closed loop lambda control. A lambda bias or offset is varied as a function of the catalyst temperature, engine speed, and engine load to bias the air/fuel ratio lean of the stoichiometric ratio. Excess air may be supplied to the catalyst for a predetermined period after a cold engine start or at any time that the catalyst temperature is below its optimum operating temperature for efficient conversion. The bias or offset is reduced to zero after the catalyst reaches a desired operating temperature or the predetermined time period expires.

摘要： Various systems and method are described for controlling an engine having an exhaust system which includes a particulate filter. One example method comprises, after shutting down the engine and spinning down the engine to rest, operating a vacuum pump to draw fresh air through the exhaust system to an intake system, and regenerating at least a portion of the particulate filter during the engine rest.

摘要： A vacuum source arbitration system is disclosed. In one example, vacuum is supplied to a vacuum reservoir via an ejector during a first condition, and vacuum is supplied to the vacuum reservoir via an engine intake manifold during a second condition. The approach may provide a desired level of vacuum in a reservoir while reducing engine fuel consumption.
