Abstract
Official abstract text for this publication.
A method for operating a boosted gasoline engine. The method includes diluting an intake air charge of the engine to a first level of dilution when operating at a stoichiometric air-to-fuel ratio. The method also includes, in response to a condition of excessive exhaust temperature downstream of the engine, diluting the intake air charge of the engine to a second, greater level of dilution while operating at an enriched air-to-fuel ratio.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for operating a boosted gasoline engine, the method comprising: diluting an intake air charge of the engine to a first level of dilution within a first dilution tolerance limit when operating at a stoichiometric air-to-fuel ratio; and diluting the intake air charge of the engine to a second, greater level of dilution within a second, greater dilution tolerance limit while operating at an enriched air-to-fuel ratio, in response to a condition…
