Abstract
The utility model discloses an exhaust muffler for an automobile. The exhaust muffler comprises a shell, wherein the two ends of the shell are provided with sealing covers, air inlet pipes and air outlet pipes; more than two flared muffling components are arranged at certain intervals in the shell; and each entire muffling component is made of a muffling material. The exhaust muffler is simple in structure, and is reasonable in design; and an original noise reduction requirement can be met, the aims of boosting and saving oil for the automobile can be fulfilled effectively, the service life of an engine is prolonged, and power is increased.
Description
Technical field
The utility model relates to and belongs to automobile technical field, particularly relates to a kind of automobile exhaust muffler.
Background technique
Automotive muffler generally is that the sealing cover by suction tude, steam outlet pipe, shell and two ends thereof forms external form, and be provided with at least successively in the enclosure the I chamber that one section center siphunculus and a slice dividing plate are divided into, another sheet dividing plate and one section off-centre or center siphunculus are divided into the III chamber, be the II chamber between two dividing plates, and the tube wall of dividing plate and siphunculus is evenly equipped with micropore, formation filtering type noise elimination exhaust structure.But this structure in use for some time, the micropore of dividing plate and sleeve pipe all can have obstruction in various degree, gently then suction tude flange punching take off or usually cause engine operating temperature to raise fast when running at high speed, fan blade does not turn, power reduces, thereby aggravation cylinder wear and increase oil consumption etc.
For addressing this problem, those skilled in the art propose between motor and the silencing apparatus socket air entraining pipe identical with cylinder block gas port quantity, in establish the additional devices such as horn sleeve barrel, bend connector of flow-limiting valve, can alleviate blockage of the micro orifice degree in the silencing apparatus, and make waste gas again do secondary combustion, play certain Synergistic and energy-saving effect.But for the Motor Vehicle of having finalized the design, be difficult to implement this scheme, because accelerate the drainage exhaust velocity, simple possible on the one side claimed structure, because automobile is usually worked, require to realize synchronously that very large difficulty will occur for noise reduction sound-deadening and Synergistic and energy-saving on the other hand under different speed, the gradient and load.
Summary of the invention
The purpose of this utility model just is to provide a kind of automobile exhaust muffler, can keep simplified structure under the prerequisite of original noise reduction sound-deadening, thereby reach the purpose of the reinforcing and oil-saving of realizing automobile, can address the above problem fully.
To achieve these goals, the technical solution adopted in the utility model is such:
A kind of automobile exhaust muffler comprises shell, and there is sealing cover at the shell two ends, and is provided with suction tude and steam outlet pipe, and the interval arranges plural tubaeform muffler part in the described shell, and this muffler part integral body is made by muffler material.
As preferably, described tubaeform muffler part surface is uniform porose.
As preferably, the semi-cone angle of described tubaeform muffler part is 35 °-55 °.
As preferably, described outer casing inner wall is provided with the silencing plate of being made by muffler material.
Compared with prior art, the utility model has the advantage of:
Simple in structure, reasonable in design, original noise reduction requirement can not only be reached, and reinforcement, the fuel-economizing purpose of automobile can be effectively realized, prolong engine life, improve power.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of the utility model muffler part.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As depicted in figs. 1 and 2, a kind of automobile exhaust muffler, comprise shell 1, there is sealing cover at shell 1 two ends, and be provided with suction tude 2 and steam outlet pipe 3, described shell 1 inwall is provided with the silencing plate 6 of being made by muffler material, three tubaeform muffler parts 4 of shell 1 interior spaced set, and these muffler part 4 integral body are made by muffler material.The toy trumpet mouth of tubaeform muffler part 4 is near suction tude 2, and the typhon mouth is near steam outlet pipe 3.Described tubaeform muffler part 4 surfaces are evenly equipped with miniature aperture 5, and the semi-cone angle α of described tubaeform muffler part 4 is 35 °-55 °.
In use, air-flow enters in the shell 1 from suction tude 2, and a part of air-flow directly passes through from the horn mouth of tubaeform muffler part 4, and another part air-flow then penetrates friction from the aperture 5 on muffler part 4 surfaces, form turbulent flow, the one-level level is discharged from steam outlet pipe 3 by the decompression of noise reduction parts 4 noise reductions successively.The semi-cone angle α of tubaeform muffler part 4 is to improve the effect of noise reduction sound-absorbing and decompression between 35 °-55 °; The internal diameter of its toy trumpet mouth is consistent with the internal diameter of suction tude 2 or steam outlet pipe 3, and is smooth and easy to guarantee the exhaust heat radiation.In practical operation, according to the air displacement of motor car engine, determine the quantity of muffler part 4, air displacement is larger, and the quantity of muffler part 4 should be more, otherwise, then fewer.
The above only is preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of within spirit of the present utility model and principle, doing, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
Claims (4)
