摘要: An engine control system that regulates fuel to an engine after lean idle operation includes a first module that determines a rich mass fuel rate based on a lean operation mass air flow and a stoichiometric air to fuel ratio (AFR) and that calculates a time rich based on the rich mass fuel rate. A second module regulates fuel to the engine during a rich operation period after the lean idle operation to provide the rich mass fuel rate for the time rich.
