The present disclosure is directed to a flexible pipe assembly that includes a pipe, a sleeve, a first connection assembly, and a second connection assembly. The pipe of the flexible pipe assembly includes a first end portion that is coupled to an external vertical exhaust pipe that allows exhaust to escape from a truck and a second end portion that is coupled to a pipe to an outlet of an exhaust aftertreatment system (EAS). The pipe also includes a third portion, which is a bellows, coupling the first end portion to the second end portion of the pipe of the flexible pipe assembly. The first and second connection assemblies couple the sleeve to the pipe of the flexible pipe assembly by passing through holes in the sleeve and the pipe of the flexible pipe assembly.

A device for safely re-directing carbon monoxide exhaust from generators includes a base, a holding mechanism, at least one support, and an exhaust tube. The base is configured to be positioned on a grounding surface. The holding mechanism is suspended at an elevated height from the base. The at least one support is connected between the base and the holding mechanism. The at least one support is configured to support the holding mechanism at the elevated height in a vertical orientation. The exhaust tube is configured to be connected to an exhaust outlet of the generator on a first end. The exhaust tube is configured to extend from the exhaust outlet of the generator vertically through the holding mechanism to a safe exhaust height above the exhaust outlet of the generator.

A replacement kit for use with a motor vehicle that was originally equipped with an exhaust system including an exhaust manifold and a catalytic converter welded thereto. The replacement kit includes a replacement catalytic converter arranged for use during use of the motor vehicle on public roads. Rather than welding, the replacement catalytic converter attaches to the exhaust manifold using a clamp to form a gas-tight seal. The clamp is arranged to move from the closed position to an open position to enable disengagement of the replacement catalytic converter from the exhaust manifold and substitution of a bypass pipe in place of the replacement catalytic converter to increase performance characteristics of the vehicle during off-road use.

Systems and methods are provided for a combined spark arrestor and muffler assembly. In one example, a system may include a combined housing, the combined housing including a spark arrestor portion including a plurality of stator fins, and a muffler portion including acoustic packing, the muffler portion fluidically coupled to the spark arrestor portion via a first sliding joint and a second sliding joint. In this way, a single component of a vehicle exhaust system may reduce sparks and/or carbon deposits in exhaust gas, while also reducing exhaust noise.

A mounting assembly for a silencer of an exhauster assembly includes a mounting plate. The mounting plate has an opening configured to receive an exhauster of the exhauster assembly while the exhauster is coupled to a structure of a vehicle at least partially separately from the mounting plate. In addition, the mounting plate has a first side configured to face the structure of the vehicle and a second side configured to face the silencer. The mounting assembly also includes at least one exhauster mounting feature configured to couple the mounting plate to the exhauster. Furthermore, the mounting assembly includes a silencer mounting feature configured to couple the silencer to the mounting plate.

An exhaust gas treatment assembly for an exhaust system of an internal combustion engine includes a housing having a circumferential wall and at least one base wall which in an external circumferential region is connected to the circumferential wall. In a housing interior space, which is defined by the circumferential wall and the base wall, at least one exhaust gas treatment unit is positioned so as to be removable from the housing. At least one base wall is an interchangeable base wall which is releasably connected to the circumferential wall via a connection assembly. The connection assembly includes a first connection portion, a first axial support portion, and on the base wall includes a second connection portion which via at least one connection member is releasably connected to the first connection portion and a second axial support portion is supported on the first axial support portion.

An aftertreatment system comprises a housing having an inlet, an outlet and a sidewall. The housing defines an internal volume structured to receive an exhaust gas via the inlet. The sidewall defines an access opening. An access panel is operatively coupled to the sidewall and covers the access opening. The access panel defines a plurality of throughholes. Each of the plurality of throughholes are configured to receive a fastener therethrough for removably coupling the access panel to the sidewall. An injection port is also defined in the access panel. An injector is positioned on the access panel. The injector is removably coupled to the access panel via a coupling assembly so that the injector is in fluidic communication with the internal volume via the injection port. A SCR system is disposed in the internal volume and includes at least one catalyst formulated to decompose constituents of the exhaust gas.

A decoupling element for an exhaust system (1) of a combustion engine, with an elastic exhaust gas-conducting body (3), with at least one support ring (7) connected to the body (3) in a fixed manner, which encloses an axial end portion (8) of the body (3) on the outside in the circumferential direction (5), and with at least one flange (9), which is fastened to the support ring (7) by means of a weld seam (12), wherein the flange (9) comprises a connecting piece (13), which is inserted in the end portion (8) of the body (3) enclosed by the support ring (7), and wherein the weld seam (12) is configured circumferential on the outside and connects an axial face end (14) of the support ring (7) facing away from the body (3) to the outer circumference (15) of the connecting piece (13) of the flange (9).

A clamp coupling includes clamp segments and a connecting section including a fastening section and a contact section. The contact section connects the clamp segments and includes a changing means to change a spaced distance between the clamp segments. The fastening section includes an externally threaded body and an internally threaded body for holding the clamp segments thereby to reduce the spaced distance between the clamp segments and connect objects. A method of fastening the clamp coupling includes holding the shim in the contact section between one ends of the clamp segments in a case that adjustment is made so that a circumferential length of the clamp segments is increased and removing the shim from the contact section so that the clamp segments are brought into direct contact with each other in a case that adjustment is made so that the circumferential length of the clamp segments is shortened.

The catalyst module is designed for use in an emission control system of an industrial scale combustion system. It comprises a stack frame, in which several mounting units, especially element boxes are inserted. Each of these is provided with several catalysts. In order to make a simple installation possible and, at the same time, a reliable sealing, the stack frame is assembled from side frame parts, which are connected and especially bolted to one another via mechanical connecting elements, a sealing element, which is inserted during the installation before the connection of the at least one side frame part and pressed against at least one element box with the help of the connecting element, being present at least at a side frame part.
