Abstract

The invention discloses a car muffler. The car muffler is characterized by comprising a tubular shell, an air inlet tube, an exhaust tube, a first partition plate and a second partition plate, wherein the air inlet tube and the exhaust tube are arranged in the shell, and the first partition plate and the second partition plate are sequentially arranged in the shell; the air inlet tube and the exhaust tube sequentially penetrate the first partition plate and the second partition plate; the positions, in a second chamber and a third chamber, of the air inlet tube are each provided with through holes; a first restriction orifice is arranged on the right side of the first partition plate; a second restriction orifice is arranged on the left side of the second partition plate, and a third restriction orifice is arranged on the right side of the second partition plate; and the first partition plate and the second partition plate are each provided with a through hole. The car muffler has the beneficial effects that the car muffler is reasonable in manufacturing process and low in manufacturing cost; normal operation cannot be influenced, and safety and reliability are achieved; and the car muffler can better attenuate noise and is good in noise elimination effect.

Description

technical field [0001] The invention relates to a muffler, in particular to an automobile muffler, which belongs to the field of automobile parts. Background technique [0002] In cities, traffic noise accounts for about 70% of various sound sources. If you live in such a noisy environment for a long time, you will get "noise disease". Experts pointed out: "One of the biggest harms caused by automobiles to the environment is noise pollution, which must be given special attention." [0003] The muffler is an important part of the car. As a part of the exhaust pipe, it can reduce the exhaust noise of the engine and enable the high-temperature exhaust gas to be discharged safely and effectively. With the continuous development of my country's automobile industry and the continuous improvement of engine performance, the noise generated by it is getting louder and louder, and the research on automobile mufflers has become the focus of enterprise research. Currently, there are ...
