Abstract: An exhaust gas recirculation cooler for an internal combustion engine is provided. The exhaust gas recirculation cooler includes an external casing with an inlet and an outlet for an exhaust gas flow. A first tube bundle and a second tube bundle, each with an inlet and an outlet for a coolant, are located inside the external casing so that the exhaust gas flow flows through the first tube bundle and the second tube bundle in series. A bypass passage conveys the exhaust gas flow from downstream the first tube bundle to the outlet of the external casing bypassing the second tube bundle. The bypass passage is located inside the external casing between the first tube bundle and the second tube bundle.

Abstract: 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.
