Abstract

The invention discloses an automobile exhaust pipe good in noise elimination. The automobile exhaust pipe comprises exhaust pipe bodies. An exhaust pipe gas outlet hole is formed in one side of each exhaust pipe body. Pipe inner bionic grains are installed on one side of each exhaust pipe gas outlet hole. Fixing threaded holes are formed in the side faces of the exhaust pipe gas outlet holes. A steel hoop is installed on one side of each exhaust pipe body. Gas outlet pipes are arranged on one sides of the steel hoops. A gas inlet cooling pipe is installed on one sides of the exhaust pipe bodies. An exhaust pipe gas inlet hole is formed in the top of the gas inlet cooling pipe. The automobile exhaust pipe good in noise elimination has the characteristics that the exhaust efficiency is high, speed increasing is quick and the noise of the exhaust pipe is low; the interaction force between gas and the solid pipe wall of the exhaust pipe is fully utilized, the function of effective resistance reduction is achieved, the exhaust resistance in an automobile exhaust manifold is effectively reduced, the exhaust efficiency of an automobile is improved, and the noise elimination effect is good.

Description

technical field [0001] The invention relates to the technical field of exhaust pipes, in particular to an automobile exhaust pipe with good noise reduction. Background technique [0002] The so-called exhaust pipe, also known as the automobile exhaust pipe hose, is installed in the exhaust pipe between the engine exhaust branch pipe and the muffler, so that the entire exhaust system is flexibly connected, thereby reducing vibration and noise, facilitating The role of installation and prolonging the life of the exhaust muffler system. The structure of the exhaust pipe is a double-layer corrugated pipe covered with a steel mesh sleeve, and the straight edge sections at both ends are covered with snap rings. In order to make the noise reduction effect better, the inside of the bellows can be Equipped with expansion joints or mesh sleeves, the main material of the exhaust pipe is stainless steel, and the material of the ferrule and the connecting pipe can be stainless steel or a...
