An engine exhaust gas dust-removal system and method. The engine exhaust gas dust-removal system comprises an exhaust gas dust-removal system inlet, an exhaust gas dust-removal system outlet, and an exhaust gas electric field device The engine exhaust gas dust-removal system has a better dust-removal effect, and can effectively remove particulate matters in engine exhaust gas.

Provided is a work vehicle in which components such as a headlamp are less likely to be affected by heat. The work vehicle includes a running vehicle body which includes running devices and to which a work machine can be replaceably connected; an engine mounted on the running vehicle body and serving as a drive source for the running devices and the work machine; a bonnet covering the engine; a headlamp attached to a front portion of the bonnet; a muffler arranged below the headlamp in an internal space of the bonnet; and a heat shield member arranged between the headlamp and the muffler.

An exhaust system component of a motor vehicle includes a gas-carrying housing, a heat shield seated on an outside of the housing, and at least one wire mesh provided at least partly between the heat shield and the housing. The wire mesh includes a first attachment point and a second attachment point. The heat shield is attached to the housing via the wire mesh, and the wire mesh is attached to both the heat shield, via the first attachment point, and to the housing via the second attachment point. The first attachment point is separate from the second attachment point.

An outboard motor catalytic converter that can downsize an outboard motor by making a space, where catalysts are installed, small and can ensure efficient reaction of the catalysts. The outboard motor catalytic converter includes exhaust pipes that are connected to exhaust manifolds of an engine of the outboard motor. Catalysts are installed inside the exhaust pipes, and at least a portion of each of the exhaust pipes, which corresponds to a place where the catalysts are installed, is formed to have a double structure constituted of an inner pipe and an outer pipe.

A component of an electrical system that includes an electrical system component structure and a thermal insulating structure for thermally insulating at least a portion of the electrical system component structure. The thermal insulating structure includes a mixture with an inorganic binder, inorganic filler particles, and water. The thermal insulating structure also includes a fabric with inorganic fibers in the form of a fiber structure. The fabric is impregnated with the mixture so as to form a pliable binder structure. The pliable binder structure is positioned on at least a portion of the electrical system component structure, and the pliable binder structure becomes a rigid binder structure in response to being dried, cured or otherwise hardened.

A decoupling element for reducing structure-borne noise, particularly for use in a heat shield system, having a sleeve element with an insertion opening for the insertion of a fastener for fastening to a partner fastener, wherein the insertion opening extends in an axial direction of the sleeve element and the sleeve element has collars protruding in a radial direction, which are spaced apart from each other in the axial direction, wherein between the collars, a damping element is positioned, which extends radially outward beyond the collars and is provided to be fastened to a heat-shielding part by means of a fastening element, and the damping element is embodied as a metal wire structure, wherein the damping element is positioned so that it is elastically prestressed in the axial direction in a gap between the collars of the sleeve element.
