ADAPTIVE REGENERATION OF AN EXHAUST AFTERTREATMENT DEVICE IN RESPONSE TO A BIODIESEL FUEL BLEND |
摘要 |
A compression-ignition engine is coupled to an exhaust aftertreatment system including a particulate filter. A method of operating the compression-ignition engine includes executing a feed-forward control scheme to determine an amount of post-combustion fuel to achieve a preferred temperature in the exhaust gas feedstream at an inlet to the particulate filter. The amount of post-combustion fuel is a nominal post-combustion fuel amount adjusted for a biodiesel blend ratio of the fuel. The post-combustion fuel is injected upstream of the exhaust aftertreatment system in response to a command to regenerate the particulate filter.
