Abstract
An automotive engine muffler is provided with a cylindrical housing with head plates on both ends. Middle of the head plate at front end of the housing is welded with an intake pipe and middle of the head plate at the back end of the housing is welded with an air outlet pipe. In the housing, two muffling grid panels parallel with the head plates are provided at an interval from the head plates; each of ends of the intake pipe and the air outlet pipe is fixed on each of the muffling grid panels and is closed. A plurality of pinholes are provided on the intake pipe and the air outlet pipe between the head plates and the muffling grid panels, and also a plurality of pinholes are provided on both of the muffling grid panels. The utility model is simple in structure, low in cost of manufacture, beautiful, firm, reduces internal resistance and kinetic loss and is able to effectively reduce exhaust noise of motors.
Description
Technical field
The utility model relates to motor car engine baffler technical field.
Background technique
Existing motor car engine baffler all adopts tube shell type structure, and some hush pipes promptly are set in housing, makes exhaust reciprocal back and forth in pipe, reaches the noise reduction purpose.Improve erasure effect, can only increase the housing volume, the lengthening hush pipe, or hush pipe is attenuated.This mobile muffler complex structure, consume material is many, and the fabricating cost height damages easily, and influences the power performance of motor, increases oil consumption.The patent No. be CN02202293.7's " a kind of motor silencer " though improve to some extent, have the many deficiencies of complex structure, consume material equally.
Summary of the invention
The purpose of this utility model is exactly the defective that will overcome prior art, provide a kind of simple in structure, cost is low, the motor car engine baffler of good muffling effect.
For achieving the above object, the technological scheme that the utility model adopted is: it has the barrel-type casing that two ends have head plate equally, is welded with suction tude in the head plate central authorities of housing front end, and the head plate central authorities in the housing rear end are welded with steam outlet pipe.Its structural feature is, in housing, be welded with two blocks of noise reduction lattice plates parallel with head plate with head plate is separated by a distance, the end of suction tude and steam outlet pipe respectively is fixed on the noise reduction lattice plate, suction tude and the steam outlet pipe end in housing is sealed, suction tude and steam outlet pipe have a plurality of apertures on the part between head plate and the noise reduction lattice plate, also have some apertures on two noise reduction lattice plates.
Motor car engine baffler as mentioned above, its suction tude and steam outlet pipe respectively are evenly distributed with 10-20 aperture on the part between head plate and the noise reduction lattice plate.
The motor car engine baffler has the 20-50 aperture on its every block of noise reduction lattice plate as mentioned above.
Motor car engine baffler as mentioned above, the diameter of the aperture on its suction tude, steam outlet pipe and the noise reduction lattice plate is 4-6mm.
Motor car engine baffler as mentioned above, a side that is positioned at suction tude at preceding noise reduction lattice plate has aperture, and opposite side is not with aperture; And on the noise reduction lattice plate of back with the aperture of last noise reduction lattice plate over against a side be not with aperture, and opposite side has aperture.
Because the utility model no longer relies on some hush pipe noise reductions, has reduced internal drag and kinetic equation loss, save fuel oil; And simple in structure, use material few, fabricating cost is low, can all adopt stainless steel to make, and beautiful shape is not fragile, can reduce the exhaust sound of motor more effectively.
Description of drawings
Fig. 1 is a longitudinal sectional view of the present utility model, shows its overall structure.
Embodiment
In the accompanying drawing illustrated embodiment, the utility model comprises that two ends have the barrel-type casing 1 of head plate 10, is welded with suction tude 6 in head plate 10 central authorities of housing 1 front end, and head plate 10 central authorities in housing 1 rear end are welded with steam outlet pipe 8.In housing 1, be welded with two blocks of noise reduction lattice plates 2,4 parallel with head plate 10 with head plate 10 is separated by a distance, on the noise reduction lattice plate 2 and on the back noise reduction lattice plate 4, suction tude 6 and the end of steam outlet pipe 8 in housing 1 were sealed by plug respectively before the end of suction tude 6 and steam outlet pipe 8 was welded on respectively.Be evenly distributed with 10-20 breeder tube 7,9 in suction tude 6 and steam outlet pipe 8 respectively on the part between head plate 10 and the noise reduction lattice plate 2,4, the diameter of aperture is 4-6mm.A side that is positioned at suction tude 6 at preceding noise reduction lattice plate 2 has 20-50 aperture 3, and opposite side is not with aperture; And on back noise reduction lattice plate 4 with the aperture of preceding noise reduction lattice plate over against a side be not with aperture, and opposite side also has 20-50 aperture 5.And the opposite side that is positioned at steam outlet pipe 8 at back noise reduction lattice plate 4 has aperture (5), and the diameter of aperture 3,5 also is 4-6mm.
