    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 treatment system includes an exhaust treatment device having a stepped outer diameter. First and second clamps each include a stepped inner diameter such that the clamps engage the exhaust treatment device and other portions of the exhaust treatment system when the exhaust treatment device is properly oriented. The exhaust treatment device interferes with one of the clamps to preclude coupling the exhaust treatment device to an adjacent portion of the exhaust treatment system when an attempt is made to install the exhaust treatment device in a reversed improper orientation. A consistent exhaust flow direction through an exhaust treatment device such as a diesel particulate filter may be maintained through use of the inventive system.

    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: A mixer for an exhaust aftertreatment system may include a housing and first and second groups of deflectors. The first group of deflectors may be disposed within the housing and may be arranged relative to each other to direct fluid flowing through the first group of deflectors into a first pair of vortices that rotate in opposite directions relative to each other. The second group of deflectors may be disposed within the housing and may be arranged relative to each other to direct fluid flowing through the second group of deflectors into a second pair of vortices that rotate in opposite directions relative to each other. The first and second groups of deflectors may be rotationally symmetric with each other about a longitudinal axis of the housing.

    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.
