Abstract
The utility model discloses an environment-friendly silencer for a car. The environment-friendly silencer comprises a body shell, wherein a central waste gas channel, a middle waste gas channel and an outer waste gas channel are arranged inside the body shell and are sleeved together sequentially from inside to outside; and the head end and the tail end are connected through a pipeline. The waste gas channels of the environment-friendly silencer is made of three-layer structural steel, so that the length of the waste gas channels is prolonged and exhaust sound is reduced greatly; and as the central waste gas channel is provided with a silent wire gauze, noise is reduced greatly and environment pollution is reduced; as an air inlet channel is clamped among the waste gas channels, air entering in a working cylinder can be pre-heated by tail gas discharged by the car and the temperature of the discharged tail gas is also reduced, energy source is not only saved, but environment pollution is also reduced. The environment-friendly silencer for the car, disclosed by the utility model, has the advantages of being compact in structure, small in space occupation, good in mechanical intensity and rigidity, great in noise reduction amount and small in power loss ratio, and satisfying with the requirements of a country on discharge and noise limit values.
Description
Technical field
The utility model relates to a kind of silencing apparatus, specifically relates to a kind of automobile and uses environment friendly silencer, belongs to the auto parts machinery field.
Background technique
Along with the develop rapidly of communication, the owning amount of city automobile also increases fast.The quick growth of city automobile has also caused the severe exacerbation of urban air, and its main cause is to have only the effect of few part noise elimination utensil with tail gas clean-up in the existing automobile, has the silencing and purifying device complex structure of automobile simultaneously now, and cost is high, is unfavorable for promoting.
The model utility content
To the deficiency that existing technology exists, the utility model technical problem to be solved is, provides a kind of automobile use environment friendly silencer, and environmental protection, noise elimination are effective, and simple in structure, easy to use, have reduced cost of production.
For solving the problems of the technologies described above; The technological scheme that the utility model is taked is; A kind of automobile is used environment friendly silencer, comprises body housing, and its body housing set inside has core exhaust gases passage, middle level exhaust steam passage and outer exhaust steam passage; Core exhaust gases passage, middle level exhaust steam passage and outer exhaust steam passage are nested together from inside to outside successively, and the head and the tail two ends connect through pipeline; The rear portion of said body housing is provided with the gas-entered passageway of taper; The gas-entered passageway set inside has the noise reduction valve of taper; Noise reduction valve is connected with gas-entered passageway through dividing plate, is connected with a flue gas leading on the rear portion end face of noise reduction valve, and flue gas leading is connected with the core exhaust gases passage; Be provided with some gas ports around said noise reduction valve and the flue gas leading joint.
Optimize, above-mentioned automobile is used environment friendly silencer, and its dividing plate is provided with some inlet holes.
Optimize, above-mentioned automobile is used environment friendly silencer, and the drift angle angle of its taper noise reduction valve is spent between 45 degree 30.
Optimize, above-mentioned automobile is used environment friendly silencer, and its center exhaust steam passage is provided with quiet chain link fence.
The beneficial effect of the utility model is: the exhaust steam passage of the utility model is the three-decker steel, has prolonged exhaust steam passage length, has reduced exhaust sound greatly; The core exhaust gases passage is provided with quiet chain link fence, can reduce noise greatly like this, reduces environmental pollution; Accompanies gas-entered passageway in the middle of the exhaust steam passage, get into air in the clutch release slave cylinder like this by the tail gas preheating of motor vehicle emission, make the discharge tail gas cooling again, both energy saving can reduce environmental pollution again; Compact structure, it is little to take up room, mechanical strength and good rigidity, sound deadening capacity is big, and power loss ratio is little, satisfies the limit value requirement of country about discharging and noise.
Description of drawings
Below in conjunction with accompanying drawing and embodiment to the utility model further explain:
Fig. 1 is the structural representation of the utility model.
Embodiment
As shown in Figure 1; The utility model is that a kind of automobile is used environment friendly silencer; Comprise body housing 1; Its body housing 1 set inside has core exhaust gases passage 2, middle level exhaust steam passage 3 and outer exhaust steam passage 4, and core exhaust gases passage 2, middle level exhaust steam passage 3 and outer exhaust steam passage 4 are nested together from inside to outside successively, and the head and the tail two ends connect through pipeline 5; The rear portion of said body housing 1 is provided with the gas-entered passageway 6 of taper; Gas-entered passageway 6 set inside have the noise reduction valve 61 of taper; Noise reduction valve 61 is connected with gas-entered passageway 6 through dividing plate 62, is connected with a flue gas leading 7 on the rear portion end face of noise reduction valve 61, and flue gas leading 7 is connected with core exhaust gases passage 2; Said noise reduction valve 61 is provided with some gas ports 71 on every side with flue gas leading 7 joints.Dividing plate 62 is provided with some inlet holes 64.The drift angle angle of taper noise reduction valve 61 is spent between 45 degree 30.Core exhaust gases passage 2 is provided with quiet chain link fence 21.The beneficial effect of the utility model is: the exhaust steam passage of the utility model is the three-decker steel, has prolonged exhaust steam passage length, has reduced exhaust sound greatly; The core exhaust gases passage is provided with quiet chain link fence, can reduce noise greatly like this, reduces environmental pollution; Accompanies gas-entered passageway in the middle of the exhaust steam passage, get into air in the clutch release slave cylinder like this by the tail gas preheating of motor vehicle emission, make the discharge tail gas cooling again, both energy saving can reduce environmental pollution again; Compact structure, it is little to take up room, mechanical strength and good rigidity, sound deadening capacity is big, and power loss ratio is little, satisfies the limit value requirement of country about discharging and noise.
Certainly, above-mentioned explanation is not to be the restriction to the utility model, and the utility model also is not limited to above-mentioned giving an example; Those skilled in the art; In the essential scope of the utility model, the variation of making, remodeling, interpolation or replacement all should belong to the protection domain of the utility model.
