摘要：
A method is described for controlling fuel vapor purging and adaptive learning in a lean burn engine system. Fuel vapor purging is carried out during lean operating conditions to minimize impact on vehicle emissions, while adaptive learning is carried out during near stoichiometric conditions (oscillations around stoichiometry). This allows faster fuel vapor purging and additional adaptive learning opportunity.
