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 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.

Abstract: An aftertreatment system may treat exhaust gas discharged from an engine. The system may include first and second selective-catalytic-reduction (SCR) catalysts and a valve. The valve may be disposed upstream of the first SCR catalyst and at least one of an oxidation catalyst and a particulate filter. The valve is connected to first and second exhaust flow paths and is movable between a first position allowing exhaust gas to flow through the first flow path and bypass the second flow path and a second position allowing exhaust gas to flow through the second flow path and bypass the first flow path. The second SCR catalyst may be a low-temperature SCR catalyst and may be disposed in the second flow path. A control module may cause the valve to move between the first and second positions based on a temperature of the exhaust gas and/or a temperature of the engine.
