Abstract
The utility model relates to a direct energy-saving silencer for internal combustion engine exhausting, which is used for exhausting and silencing of an internal combustion engine tail. The utility model which is composed of a casing barrel body and a silencing ventilating pipe is characterized in that the silencing ventilating pipe arranged in the casing barrel body is a direct pipe which can be a straight pipe or a curved pipe; a pipe wall of the silencing ventilating pipe is uniformly provided with small silencing air holes; high-temperature resistant sound absorption material is filled in the casing barrel body. The utility model can solve the problems of not ideal silencing effect, and particularly large oil consumption of the existing silencer, can have the characteristics of better silencing effect and energy saving, and can be particularly suitable for installation and use of automobiles and motorcycles.
Description
The utility model relates to a kind of silencing apparatus, especially a kind of straight-through energy-saving muffler of I. C. engine exhaust that is used for the tail exhausting silencer of internal-combustion engine.
The present internal-combustion engine that generally uses, as automobile, motorcycle etc., its tail exhaust all is equipped with multicell porous exhaust silencer, this silencing apparatus is made up of casing cylinder, suction tude and steam outlet pipe, suction tude and steam outlet pipe are provided with pore, its main interior anechoic room surface metal plate of silencing apparatus pipeline that relies on of eliminating the noise directly absorbs partly sound wave, make sound wave be converted into kinetic energy and heat energy, when sound wave transforms, sound wave and gas of combustion directly enter second anechoic room, and second anechoic room absorbs again in the same way to be subdued.Like this, the noise of the various frequencies of internal combustion tail exhaust absorbs, stops through expanded metal is surperficial several times, and the tail gas noise is reduced.But, the resistance that the internal structure of this silencing apparatus produces for the tail exhaust, the engine power loss reaches about 3%, this be a kind of be the noise elimination way of cost to sacrifice the energy.
The purpose of this utility model is to provide a kind of improved I. C. engine exhaust to lead directly to energy-saving muffler, and it not only eliminates the noise effective, and can reduce oil consumption effectively.
The utility model is achieved in that this I. C. engine exhaust leads directly to energy-saving muffler, form by casing cylinder and noise elimination breathing pipe, the noise elimination breathing pipe that is arranged in the casing cylinder is a straight-through tube, straight-through tube can be a straight tube, it also can be the curve pipe, its two ends at casing cylinder are provided with the air inlet mouth of pipe and the mouth of pipe of giving vent to anger, and the tube wall of noise elimination breathing pipe offers tiny noise elimination pore, is filled with the high-temperature resistant sound absorption material in the casing cylinder.
The utility model is because noise elimination breathing pipe tube wall is covered with little noise elimination pore eliminates the noise, and the sound-absorbing material in casing cylinder absorbs once more, so the noise elimination better effects if; Simultaneously because the noise elimination breathing pipe is straight-through tube, the tail exhaust by the time resistance that produces less relatively, so can realize reducing oil consumption, requirements of saving energy; In addition, under the operating mode that fuel consumption reduces, the power ratio like product also improves to some extent.
Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.
Fig. 1 is a kind of structural representation according to the straight-through energy-saving muffler of the I. C. engine exhaust that the utility model proposes.
Fig. 2 is another structural representation according to the straight-through energy-saving muffler of the I. C. engine exhaust that the utility model proposes.
Describe concrete structure of the present utility model in detail below in conjunction with accompanying drawing.
Embodiment 1: with reference to Fig. 1, this I. C. engine exhaust leads directly to energy-saving muffler, it is the straight-through outlet pipe silencing apparatus of a kind of single tube type, form by casing cylinder (1), a noise elimination breathing pipe (3), the noise elimination breathing pipe (3) that is arranged in the casing cylinder (1) is a cylinder straighttube-type straight-through tube, be to make with the steel wire material, its two ends at casing cylinder are provided with the air inlet mouth of pipe (6) and the mouth of pipe of giving vent to anger (2), better for the acoustically effective that makes silencing apparatus, in casing cylinder, be filled with fine perlite (4).
Embodiment 2: with reference to Fig. 2, this I. C. engine exhaust leads directly to energy-saving muffler, it is the straight-through outlet pipe silencing apparatus of a kind of double hose, be by casing cylinder (1), two noise elimination breathing pipes (3) are formed with the branch gas anechoic room (5) that is connected with two noise elimination breathing pipes, two breathing pipes (3) that are arranged in the casing cylinder (1) are cylinder curve tubular type straight-through tube, be to make with the steel wire material, two breathing pipes (3) are connected on the branch gas anechoic room (5) simultaneously, divide gas anechoic room (5) to be provided with the air inlet mouth of pipe (6), two breathing pipes (3) are respectively arranged with the mouth of pipe (2) of giving vent to anger at the other end of casing cylinder, in order can fully to absorb sound, in casing cylinder, be filled with fine perlite (4).
Claims (3)
1. an I. C. engine exhaust leads directly to energy-saving muffler, form by casing cylinder (1) and noise elimination breathing pipe (3), it is characterized in that the noise elimination breathing pipe (3) that is arranged in the casing cylinder (1) is a straight-through tube, its two ends at casing cylinder are provided with the air inlet mouth of pipe (6) and the mouth of pipe of giving vent to anger (2), the tube wall of noise elimination breathing pipe (3) offers tiny noise elimination pore, is filled with high-temperature resistant sound absorption material (4) in the casing cylinder.
2. I. C. engine exhaust according to claim 1 leads directly to energy-saving muffler, and the breathing pipe (3) that it is characterized in that eliminating the noise is to make with the steel wire material.
