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 shock absorber is disclosed which has a base valve assembly for controlling a flow of a working fluid between a reservoir chamber and a working chamber of the shock absorber. The base valve makes use of at least one digital valve assembly. The digital valve assembly communicates with an intermediate chamber formed between an intermediate tube and a pressure tube of the shock absorber. The digital valve assembly controls flow of the working fluid between the intermediate chamber and the reservoir chamber, to help control a damping action provided by the shock absorber.

Abstract: An injector for injecting a reagent includes an axially translatable valve member positioned within a housing. An electromagnet is positioned within the housing and includes a cylindrically-shaped coil of wire. The valve member moves between a seated position and an unseated position in response to energizing the electromagnet. A flux sleeve passes through the coil and includes two magnetic portions interconnected by a flux bridge portion or a flux break portion. Each of the magnetic portions is aligned with transverse planes defined by the ends of the cylindrical coil. The flux bridge portion or flux break portion is axially positioned between the transverse planes.

Abstract: An exhaust treatment fluid delivery system (16, 22, 116) may include a supply passageway (46, 146), a supply manifold (38, 138), injectors (42, 142), a bypass passageway (50, 150) and first and second pressure sensors (34, 134, 40, 140). The supply passageway (46, 146) receives the exhaust treatment fluid from a tank (26, 126) and provides the exhaust treatment fluid to the supply manifold (38, 138). The bypass passageway (50, 150) connects the supply passageway (46, 146) with the return passageway (48, 148) and includes a bypass valve (36, 136) controlling fluid flow therebetween. The first pressure sensor (34, 134) measures a first pressure of exhaust treatment fluid in the supply passageway (46, 146) based upon which the bypass valve (36, 136) is controlled. The second pressure sensor (40, 140) measures a second pressure of exhaust treatment fluid in the supply manifold (38, 138) based upon which the injectors (42, 142) are controlled.

CPC classification number: F16F9/5126 , F16F9/348 , F16F9/50
Abstract: A shock absorber has a pressure tube with a piston assembly slidably disposed within the pressure tube and attached to a piston rod. The pressure tube is disposed within a reserve tube and a working fluid reservoir is formed between the pressure tube and the reserve tube. The piston assembly divides the pressure tube into an upper working chamber and a lower working chamber. A base valve assembly controls a flow of working fluid between the working fluid reservoir and the lower working chamber. The base valve assembly includes a frequency dependent valve system that provides an increased level of damping for each compression stroke of the piston assembly during low frequency movements of the shock absorber. A lesser level of damping is provided for each compression stroke during high frequency movements of the shock absorber.
