Embodiment Construction

[0022] The present invention will be further described below in conjunction with the accompanying drawings.

[0023] Such as Figure 1 to Figure 6 As shown, a kind of internal combustion engine hot tail gas treatment device of the present invention comprises a pipe body 1 and a heating belt 2, the pipe body 1 is a Venturi tube structure, an opening 13 is arranged on the outer wall of the small end of the pipe body 1, and the heating belt 2 is wound On the outer wall of the large end of the pipe body 1. It should be understood by those skilled in the art that the preferred tube body 1 of this device is a Venturi tube structure, that is, a Venturi tube, so that the tube body 1 is a variable diameter structure, and an opening 13 is provided on the side wall of the small end of the tube body 1 , while the heating tape 2 is directly wound on the pipe body 1 . In actual use, the two ends of the pipe body 1 are directly connected to the automobile muffler and the exhaust pipe, so t...

Abstract

The invention discloses an internal combustion engine thermal exhaust treatment device, and belongs to the technical field of automobile exhaust treatment. The device comprises a tube body (1) and a heating strip (2), the tube body (1) is of a venturi tube structure, an opening (13) is formed in the small end outer wall of the tube body (1), and the heating strip (2) is wound on the large end outer wall of the tube body (1). The device is simple in structure, convenient to mount, high in exhaust treatment effect, and high in work stability, during the actual use, the two ends of the device tube body (1) are fixed between an automobile exhaust pipe and a silencer, as the internal combustion engine exhaust is the high-speed air flow, the rapid sucking-in of the oxygen can be achieved throughthe internal and external pressure difference, heating is achieved through the heating strip (2), the purpose of oxygenation increasing and heating for secondary combustion is achieved, and the problems that existing automobile exhaust treatment is inconvenient and is prone to causing the chemical pollution are solved.

Description

technical field [0001] The invention discloses a thermal exhaust gas treatment device of an internal combustion engine, which belongs to the technical field of automobile exhaust gas treatment. Background technique [0002] With the continuous improvement of automobile exhaust emission requirements, the automobile exhaust treatment standards are becoming more and more stringent, and the improvement of the automobile exhaust treatment effect is one of the necessary innovative designs. After years of continuous development and innovation, the technology of automobile exhaust treatment has reached a very considerable level. At present, the common automobile exhaust processors on the market are basically three-way catalytic converters or urea catalytic converters, which have obvious disadvantages, limited purification effect, and are prone to produce new pollutants, especially the urea catalytic converters used in commercial vehicles, which require consumption A large amount of...
