Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of exhaust pipes, and in particular relates to a double exhaust pipe structure. Background Art
[0002] The vehicle exhaust system refers to the system that collects and discharges exhaust gas. The exhaust pipe assembly is an important part of the exhaust system. It generally includes an exhaust pipe and a three-way catalytic converter installed in the exhaust pipe. One end of the exhaust pipe is used to connect to the engine, and the other end is connected to the muffler for discharge.
[0003] For example, the Chinese patent with patent announcement number CN202140140U discloses a diesel engine exhaust system, including a front section of an exhaust pipe, a three-way catalytic converter and a muffler assembly, which are connected in sequence. The muffler assembly consists of a muffler, a middle section of the exhaust pipe connected to the front end of the muffler, and a rear section of the exhaust pipe connected to the rear end of the muffler. The muffler assembly is flange-connected to the three-way catalytic converter through the middle section of the exhaust pipe, and the front section of the exhaust pipe is flange-connected to the three-way catalytic converter.
[0004] The exhaust pipe is connected to the engine muffler, making the entire exhaust system flexibly connected, thereby reducing vibration and noise, facilitating installation and extending the life of the muffler system. The exhaust pipe is generally provided with an exhaust tail pipe at the rear end, and its main function is to remove exhaust gas. Usually a single-tube exhaust pipe is used for discharge. The single-tube exhaust pipe has very loud noise and is relatively simple in structure. The exhaust gas discharged from the single-tube exhaust pipe cannot be completely dispersed in time and is easy to accumulate to produce black smoke. At this time, a double-row exhaust pipe is often required. For this purpose, an improved double exhaust pipe structure is designed. Utility Model Content
