Exhaust tail pipe of hazardous chemical vehicle

Abstract

The invention relates to the technical field of engine exhaust systems, in particular to an exhaust tail pipe of a hazardous chemical vehicle. The exhaust tail pipe comprises a tail pipe body and a guide face, the tail pipe body comprises a gas inlet and an exhaust port, and the gas inlet is used for being connected with a postprocessor; and the guide face is connected to the exhaust port. The exhaust tail pipe has a using state, when the exhaust tail pipe is in the using state, the gas inlet is connected with the postprocessor, the guide face inclines towards the ground so that the exhaust path of tail gas exhausted through the exhaust port can incline towards the ground, and a gas inlet pipe of the postprocessor is located outside the exhaust path. The problems that the exhaust tail pipeis very long, consequently, the manufacturing cost of a whole vehicle is greatly increased; and in addition, in order to avoid interference with other structures at a front wall of a cab, the exhausttail pipe needs to be bent at multiple positions, and the exhaust efficiency of the exhaust tail pipe is affected are solved.

Description

technical field [0001] The present application relates to the technical field of engine exhaust systems, in particular to an exhaust tailpipe for a vehicle with hazardous chemicals. Background technique [0002] At present, according to the regulations on the safety and technical conditions of motor vehicle operation, the installation of exhaust pipes of hazardous chemical vehicles is stipulated. Greater than or equal to 200mm, the outlet of the exhaust pipe should be installed in front of the front face of the tank / cabinet and not higher than the upper plane of the vehicle longitudinal beam, and a motor vehicle exhaust spark arrester that meets the regulations should be installed. [0003] related technologies, such as figure 1 with figure 2 As shown, the engine is connected to the after-processor 2 through the intake pipe 20 of the after-processor 2, and the exhaust gas generated by the engine is discharged into the after-processor 2 through the intake pipe 20 of the af...

AI Technical Summary

Problems solved by technology

[0005] The embodiment of the present application provides a hazardous chemical vehicle exhaust tailpipe to solve the problem that the length of the exhaust tailpipe in the related art is very long, which greatly increases the manufacturing cost of the whole vehicle; Interference, the exhaust tailpipe needs to be bent in multiple places, which affects the exhaust efficiency of the exhaust tailpipe
