Abstract

The invention discloses an exhaust pipe and a vehicle. The exhaust pipe comprises a pipe body, a sealing valve and a supporting piece, a drain hole is formed in the pipe body; the sealing valve is mounted on the pipe body and the drain hole is sealed by the sealing valve; and the supporting piece selectively supports the pipe body to separate the sealing valve and the pipe body, thereby releasing sealing of the sealing valve to the drain hole. According to the exhaust pipe, normal exhaust of the vehicle can be ensured, generation of exhaust noise can be avoided, the NVH performance of the vehicle is ensured, accumulated water can also be drained after the vehicle finishes running so that the freezing condition of the exhaust pipe in winter can be avoided, and the normal use of the vehicle can be ensured.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to an exhaust pipe and a vehicle with the exhaust pipe. Background technique [0002] In the related technology, the larger muffler package of a single unit will affect the layout of the whole vehicle. The larger the muffler package layout, the risk of exhaust pipeline layout, that is, the exhaust pipeline will be adaptively adjusted. The line will likely be at the lowest point in the exhaust system. [0003] In winter, there is a risk of freezing the exhaust pipe at its lowest point. Because the exhaust system is to discharge the exhaust gas out of the engine after the fuel is burned, the combustion will also produce water vapor, which is also discharged along the exhaust system. But in winter, after the vehicle is turned off, there will be too much water, which will freeze, block the exhaust system, and make it difficult to start. [0004] Once this problem occurs in the marke...
