Problems solved by technology

[0002] There will be quite a lot of noise when the motor vehicle is running. Usually, installing a muffler on the exhaust pipe of the car is an effective means of reducing noise. Cavity cascading to enhance the noise reduction effect, there is still room for improvement in the noise reduction utilization rate and noise reduction effect of the cavity

Embodiment Construction

[0020] The present invention will be further described in detail below with reference to the embodiments and accompanying drawings, but the embodiments of the present invention are not limited thereto.

[0021] Embodiment 1 of the present invention is, as figure 1 , figure 2 , image 3 As shown, it includes a muffler cylinder 10, an intake pipe 21, and an exhaust pipe 22. The muffler cylinder is integrally sealed, and the two end faces of the muffler cylinder are respectively an air inlet end face and an exhaust end face. There is an inclination angle between the inlet end face, the exhaust end face and the axial direction of the muffler cylinder, and the inclination direction is reversed to the exhaust end face, and the intake pipe 21 extends from the inlet end face into the muffler cylinder 10 to the exhaust end face of the muffler cylinder Fixed, here the intake pipe does not protrude from the exhaust end face, and the exhaust pipe 22 extends into the muffler cylinder 10...

Abstract

The invention discloses a laterally-open through groove silencer which comprises a silencer drum, an air inlet pipe and an exhaust pipe. The silencer drum is integrally sealed, two end faces of the silencer drum are respectively an air inlet end face and an exhaust end face, the air inlet end face and the exhaust end face form inclination angles with the axial direction of the silencer drum, and the inclination direction is towards the exhaust end face. The laterally-open through groove silencer further comprises a partition plate, the partition plate divides the silencer drum into an upper cavity and a lower cavity, the connecting line position where the air inlet pipe and the exhaust pipe are located on the cross section of the silencer drum is positioned on the midperpendicular of the partition plate, and two sides of a projection line of the air inlet pipe of the partition plate are respectively provided with at least one partition plate through grooves symmetric with respect to the projection line. The technical characteristics of the silencer in various aspects such as the noise reduction effect and heat dissipation performance are improved by adopting a cascade mode of the upper cavity and the lower cavity and ingenious design of an internal structure, and the laterally-open through groove silencer is simple and stable in structure, good in use stability and long in service life.

Description

technical field [0001] The invention relates to a muffler with a side opening slot. Background technique [0002] There will be quite a lot of noise when the motor vehicle is running. Usually, installing a muffler on the exhaust pipe of the car is an effective means of reducing noise. There is still room for improvement in the utilization rate of the cavity and the noise reduction effect. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a muffler with open side slots. On the basis of the basic resistance muffler, the muffler with side open slots has improved the previous structural form of axial cascading of resistive chambers. The cascading form of the upper and lower chambers and the ingenious design of the internal structure have improved the technical characteristics of the muffler in all aspects. The specific principles and effects include: 1. The previous communication method relying on pipes and pipe openi...
