A support component that supports a shielding member, and a fixing component that fixes the shielding member to the structure via the support component. The support component has a cylindrical part, two flange parts and spring part. The spring parts have a first spring and a second spring with different load-deflection characteristics. The first spring and the second spring are interposed between each of the two flange parts and both sides of the shielding member. As a result, the invention provides a sufficient buffering effect.

Clamp insulation systems and methods are disclosed. An example clamp system includes a foil cover having a top surface with a support structure, side walls and tapered end walls. The foil cover can define a pocket between the top surface, side walls and end walls. The insulation system further includes an insulation layer disposed in the pocket between the sidewalls and adjacent an inside of the top surface. The side walls can have a depth so that the pocket is capable of receiving a band of a clamp and so that the side walls are capable of being crimped about the band of the clamp.

An isolator for supporting an exhaust component from a portion of a vehicle via a hanger includes elastomeric isolator element having at least one aperture adapted to receive the hanger and an isolator or bracket for receiving and supporting the elastomeric isolator element. The isolator bracket includes a mounting structure including a first aperture and a second aperture. The isolator bracket is adapted to be fixed to the vehicle by a single fastener extending through the first aperture. The second aperture extends through the isolator bracket and includes an internal wall shaped as a polygon. A target orientation of the isolator bracket relative to the vehicle is obtained when the internal wall of the second aperture is angularly oriented and coaxially aligned with a corresponding aperture in the portion of the vehicle having an internal surface with the same polygon shape as the second aperture.

A watercraft and a marine engine assembly for pivotably mounting to a watercraft about a tilt-trim axis are disclosed. The marine engine assembly includes an engine unit including: an engine unit housing; an engine disposed in the housing; and an exhaust conduit disposed in the housing, an exhaust inlet defined by the exhaust conduit being fluidly connected to the engine, the exhaust conduit extending forward and upward from the exhaust inlet and then subsequently extending downward and rearward to an exhaust outlet. The marine engine assembly also has a driveshaft operatively connected to the engine and a propulsion device operatively connected to the driveshaft. A center of mass of the engine is disposed below the tilt-trim axis at least when the driveshaft is vertically oriented.

A replacement kit enables a user to generate a desired audible sound from an exhaust system of a motor vehicle. The kit includes a replacement catalytic converter arranged to replace the vehicle's original equipment catalytic converter. The replacement catalytic converter is connected to the vehicle's factory muffler through a replacement pipe segment to obtain a more desirable, yet muffled engine sound. The factory muffler may be removed from the motor vehicle and the replacement catalytic converter may instead be connected to a muffler bypass pipe or pipes or replacement exhaust components/segments which channels the exhaust flow directly to the atmosphere to obtain a more powerful unmuffled exciting visceral sports car engine sound.

An outboard motor includes a first exhaust passage connected to an exhaust port and extending downward from the exhaust port through a support frame on a lateral side of a cylinder head. A first case accommodates an engine. A second case accommodates a propeller shaft. A third case is between the first case and the second case in a vertical direction. An exhaust pipe is between the first case and the second case in the vertical direction. The exhaust pipe is connected to the first exhaust passage. At least a portion of the exhaust pipe is outside the third case as seen in a side view of the outboard motor. An exterior cover is between the first case and the second case in the vertical direction. The exterior cover covers the exhaust pipe.

An engine device includes an exhaust gas purification device above a cylinder head through a support pedestal. The support pedestal has a flat portion on which the exhaust gas purification device is mounted, and a plurality of legs which protrude downward form the flat portion and are fixed to the cylinder head. The flat portion and the leg portion are formed integrally. Portions between the legs are each formed in an arch-shape.

An isolator for supporting an exhaust component from a portion of a vehicle via a hanger includes elastomeric isolator element having at least one aperture adapted to receive the hanger and an isolator or bracket for receiving and supporting the elastomeric isolator element. The isolator bracket includes a mounting structure including a first aperture and a second aperture. The isolator bracket is adapted to be fixed to the vehicle by a single fastener extending through the first aperture. The second aperture extends through the isolator bracket and includes an internal wall shaped as a polygon. A target orientation of the isolator bracket relative to the vehicle is obtained when the internal wall of the second aperture is angularly oriented and coaxially aligned with a corresponding aperture in the portion of the vehicle having an internal surface with the same polygon shape as the second aperture.

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.

The present invention relates to a gas heat pump system. The gas heat pump system, according to one embodiment of the present invention, comprises: an air conditioning module comprising a compressor, an outdoor heat exchanger, an expansion apparatus, an indoor heat exchanger and a refrigerant line; and an engine module comprising an engine for combusting a mixture of fuel and air, thereby providing power for driving the compressor. The engine module comprises: a mixer for mixing and discharging the air and fuel; a supercharging means for receiving the mixture discharged from the mixer, compressing same, and then discharging same; an intercooler for receiving the mixture compressed in the supercharging means, cooling same by a heat exchange method, increasing the density thereof, and then discharging same; an adjustment means for receiving the mixture discharged from the intercooler, adjusting the quantity thereof, and then supplying same to the engine; and an exhaust gas heat exchanger for exchanging heat between a coolant and exhaust gas discharged from the engine, wherein the exhaust gas heat exchanger is directly connected to an exhaust manifold of the engine.
