Abstract: A manufacturing method of a sub-muffler includes a rectangular tubular body shaping step, a preliminary shaping step, and a diameter reduction shaping step. In the rectangular tubular body shaping step, a plate material is bent and a rectangular tubular body having a rectangular shape in cross section is thereby formed. In the preliminary shaping step, ends of the rectangular tubular body are preliminarily formed and the end parts of the tubular body are thereby formed so that its cross-sectional shape becomes a circular shape. In the diameter reduction shaping step, the diameters of the ends of the rectangular tubular body are reduced.

Abstract: Idle relief mufflers are configured to discharge exhaust gases from an outboard motor to atmosphere surrounding the outboard motor when an internal combustion engine of the outboard motor is operated at idle and at low speeds. The idle relief mufflers comprise a housing having an open interior, an inlet port configured to convey the exhaust gases to the open interior, and an outlet port configured to discharge the exhaust gases from the open interior. An exhaust grommet is connected to the outlet port. The exhaust grommet comprises a body that is configured to engage with a cowl of the outboard motor and an extension that extends through the outlet port and protrudes into the open interior. The extension and the body together define a through-bore that is configured to convey the exhaust gases from the open interior to the atmosphere.

Abstract: An engine exhaust-driven heating device generates a high volume, steady stream of hot gas by passing an exhaust stream from a gasoline, propane, natural gas, or combustible fueled internal combustion engine through a catalyst that reduces the atmospheric emissions of the stream and liberates the energy of the pollutants in the stream. The device then combines the catalytic-treated air stream with a fresh air stream to further react with remaining pollutants and generate additional heat. The hot gas may be used to dry a variety of surfaces and, when integrated without other components typically found in surface drying equipment, provides an ideal system for use in a variety of moderate- to large-sized portable surface drying equipment. The heating device provides a reliable and continuous heat source and, when integrated into a controlled delivery system, dries the moisture from a surface faster and more effectively than prior art heating devices.

Abstract: An exhaust muffler device for an combustion engine includes: a first expansion chamber into which exhaust gas from a combustion engine flows; a second expansion chamber disposed downstream of the first expansion chamber; a resonance chamber that is disposed adjacent to the first expansion chamber and communicates with an exhaust passage; a discharge passage through which the exhaust gas that flows into the resonance chamber is discharged to the outside; and an exhaust valve disposed in a second partition wall between the first expansion chamber and the resonance chamber. The exhaust valve opens when pressure in the first expansion chamber attains a value greater than a predetermined value.
