Embodiment Construction

[0016] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0017] In the figure: 1-curling, 2-exhaust pipe body, 3-radiation layer, 4-anti-oxidation layer, 5-exhaust gas filter device, 6-connector.

[0018] The outlet end of the exhaust pipe body 2 is provided with a crimp 1 bent into the pipe body. The design of the crimp 1 can improve the strength of the pipe body. The other end of the exhaust pipe body 2 is provided with a connecting piece 6, and the exhaust gas filter device 5 is located inside the exhaust pipe body 2, which can purify the exhaust gas so that the discharged exhaust gas can meet the national emission standards. The heat dissipation layer 3 is located on the outer surface of the exhaust pipe body 2, and the residual heat energy on the exhaust pipe body 2 can be passed through The heat di...

Abstract

The invention relates to an exhaust pipe which comprises a turned edge, an exhaust pipe body, a heat-dissipating layer, an antioxidation layer, a tail gas filtering device and a connecting piece, wherein the outlet end of the exhaust pipe body is provided with the turned edge bent towards the interior of the exhaust pipe body; the other end of the exhaust pipe body is provided with the connecting piece; the exhaust pipe body is of an integral structure molded once; the tail gas filtering device is positioned in the exhaust pipe body and can purify tail gases; the heat-dissipating layer is positioned at the external surface of the exhaust pipe body and wraps the whole exhaust pipe body; the antioxidation layer is positioned at the outer side of the heat-dissipating layer. Therefore, the problems of low strength and slow cooling are solved.

Description

technical field [0001] The invention belongs to the technical field of auto parts, in particular to an exhaust pipe. Background technique [0002] Exhaust pipes are used to discharge automobile exhaust. During the exhaust process, the exhaust gas has a high temperature, has a certain impact force, and is easy to be corroded. Therefore, in the design process of the exhaust pipe, the strength and resistance of the exhaust pipe The degree of corrosion, especially the strength of the outlet end of the exhaust pipe is particularly important. At present, the strength and corrosion resistance of the exhaust pipe are generally improved by increasing the wall thickness of the exhaust pipe, but as the thickness increases, the production cost also increases accordingly. [0003] A car is a machine powered by an internal combustion engine. Its fuel is usually diesel or gasoline and other oil products. The combustion of oil products will produce a large amount of exhaust gas, which need...
