Abstract: A vehicle control system includes: a fuel control module configured to control gasoline fueling of an engine in open loop based on a target engine lambda; and a burner control module configured to control gasoline fueling of a burner based on (a) a target lambda input to a three-way catalyst (TWC) in an exhaust system of the engine and (b) a lambda of exhaust input to the TWC. The burner is coupled to the exhaust system between (a) an output of the engine and (b) an input to the TWC.

Abstract: A system includes an engine having multiple cylinders and an exhaust manifold. A fuel delivery device and an igniter are disposed in the exhaust manifold. The fuel delivery device injects a fuel into the exhaust manifold. The system also includes an exhaust aftertreatment setup in fluid communication with the exhaust manifold, and a controller in communication with the multiple cylinders, the fuel delivery device and the igniter. The controller is configured to deactivate at least one cylinder to provide air to the exhaust manifold, and control the fuel delivery device to provide the fuel within the exhaust manifold such that the fuel and the air from the at least one deactivated cylinder forms a mixture within the exhaust manifold. The controller is configured to control the igniter to ignite the mixture to generate combustion products within the exhaust manifold for heating the exhaust aftertreatment setup.
