    摘要： An exhaust treatment system for a work vehicle includes a mixing conduit extending between upstream and downstream ends along a bulk flow direction, where the upstream end receives engine exhaust. The system further includes an injector nozzle configured to inject exhaust reductant into the mixing conduit at a location between the upstream and downstream ends. Additionally, the system includes a branch conduit, where an inlet end of the branch conduit is fluidly coupled to the mixing conduit upstream of a location at which an outlet end of the branch conduit is fluidly coupled to the mixing conduit. A portion of the exhaust flowing through the mixing conduit may be directed through the branch conduit, where the outlet end of the branch conduit is configured to direct the portion of the exhaust back into the mixing conduit such that a spiraling flow of the exhaust is generated within the mixing conduit.

    摘要： An exhaust discharge system is disclosed. The exhaust discharge system comprises an exhaust stack including a first conduit and a second conduit. The first conduit defines a first flow passageway and arranged around a first longitudinal axis. The first conduit including a skirt portion and a body portion disposed downstream of the skirt portion, and the skirt portion is oriented to slope outward from the body portion. The second conduit is disposed downstream of the first conduit. The second conduit defines a second flow passageway and is arranged around a second longitudinal axis, the second conduit includes a sidewall and an exit port, the exit port having an exit-port cross-section, wherein the exit-port cross-section is oblong in shape. The second longitudinal axis is disposed at an intersection angle to the first longitudinal axis, the intersection angle in a range of 125° to 150°. The exhaust stack is configured to convey treated exhaust from the skirt portion to the exit port.

    摘要： Disclosed herein is a catalytic converter anti-theft device for motor vehicles. The anti-theft device a motor vehicle catalytic converter anti-theft device comprises a first shell component configured to surround, at least in part, a first portion of a motor vehicle catalytic converter. A second shell component is configured to surround, at least in part, a second portion of the motor vehicle catalytic converter. The first shell component and the second shell component are configured to be attachable to each other in coaxial relation about the first portion of the catalytic converter and the second portion of the catalytic converter, respectively. A distal end of at least the first shell component comprises a structure configured to prevent axial movement of the first shell component relative to the catalytic converter. At least the first shell component further may be attachable to a fixed component of the motor vehicle.

    摘要： An engine is provided with an engine body, a crankshaft, a cooling fan, an exhaust manifold, a supercharger, an ATD that purifies exhaust gas, and a second exhaust pipe. When the height direction of the engine is defined as a first direction, the crankshaft extends in a second direction vertical to the first direction. The cooling fan is disposed on one side of the engine body in the second direction. The supercharger is driven by the exhaust gas from the exhaust manifold. The second exhaust pipe connects the supercharger and the ATD. The ATD is disposed in an attitude in which the longitudinal direction thereof is parallel to the second direction. The second exhaust pipe is connected to the cooling fan side of the ATD in the second direction. The second exhaust pipe is disposed so as to pass laterally with respect to the exhaust manifold and below the supercharger.
