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.
