An exhaust treatment system includes first and second exhaust conduits positioned on opposite ends of an exhaust treatment device. The exhaust treatment device includes a housing having a first outer diameter at a first end and a different second outer diameter at a second end. A clamp includes an inner surface engaging both the first exhaust conduit and the exhaust treatment device when the exhaust treatment device is positioned with its first end adjacent to the first exhaust conduit. The inner surface of the clamp is spaced apart from one of the housing and the exhaust treatment device when the second end of the exhaust treatment device is adjacent the first exhaust conduit.

The present disclosure relates to an air spring apparatus for use with a cabin of a vehicle. The apparatus has an upper assembly, a lower assembly, a shock absorber, a bladder, a flexible bumper element and a control element. The shock absorber has a piston rod protruding therefrom and extending through the other one of the upper and lower assemblies. The bladder is attached to the upper and lower assemblies. The flexible bumper element is secured to the piston rod adjacent one of the upper and lower assemblies, and secured to the other one of the upper and lower assemblies. The control element is secured to the flexible bumper element at a first end, and to a valve at a second end, and controls operation of the valve. The flexible bumper element can flex in response to torsional or tilting forces experienced by the one of the upper and lower assemblies, to thus help to limit these forces from being imparted to the control element.

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.
