Abstract

A vehicle includes an engine, a fueling system, an exhaust assembly, and a controller. The fueling system controls fuel to the engine. The exhaust assembly releases combustion gas from the engine and includes at least one sensor and a catalytic converter. The controller is configured to control the engine, the fueling system and the exhaust assembly. The controller evaluates engine state and an output from the at least one sensor and commands a fueling strategy to control an oxygen storage capacity of the catalytic converter based on the engine state and output from the at least one sensor.
