Efficient and environment-friendly automobile muffler

Abstract

The invention discloses an efficient and environment-friendly automobile muffler. The efficient and environment-friendly automobile muffler comprises a shell. A sound absorbing layer is arranged in the shell. A water filtering layer is arranged at one end in the shell. One end of the water filtering layer is fixedly connected with an air inflow pipe. The air inflow pipe penetrates through the shell and stretches to the left side face of the shell. One end of the air inflow pipe is connected with one end of the water filtering layer. The other end of the water filtering layer is fixedly connected with one end of an activated carbon layer. The other end of the activated carbon layer is connected with one end of a diversion pipe and one end of a muffling plate. The other end of the diversion pipe is closed. A gap is reserved between the diversion pipe and the muffling plate. The other end of the muffling plate is fixedly connected with one end of a metal net layer. The other end of the metal net layer is fixedly connected with one end of a muffling cotton layer. The other end of the muffling cotton layer is fixedly connected with an exhaust pipe. The efficient and environment-friendly automobile muffler is simple in structure, convenient to use, efficient and suitable for being widely popularized, energy is saved, and environmental protection is facilitated.

Description

technical field [0001] The invention relates to the technical field of auto parts, in particular to an efficient and environment-friendly automobile muffler. Background technique [0002] Automobile mufflers are mainly used to reduce the noise generated by motor vehicle generators. It is a device that allows airflow to pass through, but can prevent or reduce sound transmission. It is an important measure to eliminate aerodynamic noise. Car mufflers can block the propagation of sound waves and allow airflow to pass through, which is an effective tool for noise control. Traditional automobile mufflers have complex structures, large space volumes, and high production costs. Moreover, traditional automobile mufflers adopt a multi-chamber structure, and the pressure inside the shell is high, which is easy to form a large resistance to engine exhaust, which is not conducive to fuel consumption. If the combustion is complete, it is easy to form harmful gases and a large amount of ...

AI Technical Summary

Problems solved by technology

Traditional automobile mufflers have complex structures, large space volumes, and high production costs. Moreover, traditional automobile mufflers adopt a multi-chamber structure, and the pressure inside the shell is high, which is easy to form a large resistance to engine exhaust, which is not conducive to fuel consumption. The full combustion, easy to form harmful gas and a lot of heat, pollute the environment and not energy-saving

The life of the existing mufflers is relatively short. The root cause is that the exhaust gas of the automobile contains a large amount of corrosive gases. After entering the muffler, these corrosive gases will corrode the inside of the muffler, thereby shortening the life of the muffler.
