    Abstract: A method of determining an optimized position for a burner in an exhaust aftertreatment system includes estimating temperature distributions across faces of exhaust treatment devices positioned within parallel paths based on an initial burner position upstream of the parallel paths. A temperature distribution across the faces of the exhaust treatment device is again estimated based on a changed burner position. A difference between the estimates is determined. The changing, estimating and determining steps are repeated to correlate the burner position with a temperature variance across the faces. An optimized burner position is determined based on minimizing the temperature variance across the faces of the exhaust treatment devices.

    Abstract: Exhaust system for a dual-fuel engine that is provided with a first fuel and a second fuel. The exhaust system includes an exhaust passageway, with an exhaust treatment component provided in the exhaust passageway. A thermal enhancement device communicates with the exhaust passageway and is located upstream from the exhaust treatment component, wherein the thermal enhancement device is operable to raise a temperature of an exhaust located in the exhaust passageway during a switch between the first fuel and the second fuel that is provided to the dual-fuel engine. The exhaust treatment system can also include a by-pass pipe in communication with the exhaust passageway that by-passes the exhaust treatment component, wherein during combustion of the first fuel by the dual-fuel engine, the by-pass pipe is open. During combustion of the second fuel by the dual-fuel engine, the by-pass pipe is closed.

    Abstract: An exhaust after-treatment system includes an exhaust treatment component, a tank for holding an exhaust treatment fluid, and an exhaust treatment fluid dosing system. The dosing system includes a fluid distributor providing exhaust treatment fluid under pressure to a plurality of dosing modules that dose exhaust treatment fluid into the exhaust stream and a return for returning unused exhaust treatment fluid to the tank. A valve is positioned between the fluid distributor and the return and is configured to allow a flow of exhaust treatment fluid from the return to the fluid distributor before being returned to the tank during a purge operation. A controller is configured to open the valve and allow communication between the return and the fluid distributor during the purge operation such that unused exhaust treatment fluid drains during the purge operation.

    Abstract: An exhaust system for a dual-fuel engine includes an exhaust treatment component in an exhaust passageway. The exhaust treatment component is configured to treat exhaust from the combustion of a second fuel and not from combustion of a first fuel. A thermal enhancement device is in communication with the exhaust passageway and positioned upstream from the exhaust treatment component. A controller activates and deactivates the thermal enhancement device based on switching from the first fuel to the second fuel, wherein the first fuel has a higher sulfur content than the second fuel. The thermal enhancement device increases the temperature of an exhaust to combust a residual amount of the first fuel present in the exhaust passageway during the switch between the first fuel and the second fuel.
