Embodiment Construction

[0036] The present invention will be described in detail below with reference to the accompanying drawings and examples. It should be noted that, in the case of no conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other. For the convenience of description, if the words "up", "down", "left" and "right" appear in the following, it only means that the directions of up, down, left and right are consistent with the drawings themselves, and do not limit the structure.

[0037] An internal combustion rail vehicle exhaust stack, such as figure 1 As shown, it includes an exhaust guide cover 1, a chimney body 2 and an exhaust bellows 3. The exhaust guide cover 1 is fixed on the top of the chimney, and the exhaust bellows 3 is fixed on the bottom of the chimney.

[0038] The chimney body structure provided by the invention is as figure 2 As shown, it includes an inner layer 4, a thermal insulation layer 5 and a skin 6. T...

Abstract

The invention discloses an exhaust chimney of an engine and a mounting structure of the exhaust chimney. The exhaust chimney of the engine comprises a chimney body. The chimney body sequentially comprises an inner layer, a heat insulation layer and skin from inside to outside. The skin is shorter than the inner layer and the heat insulation layer, and the portions, located at the two ends of the chimney body, of the heat insulation layer are overhead. The inner layer comprises a straight pipe and a top bent pipe located at the top. By adoption of the exhaust chimney, the weather resistance of a product structure and the reliability of a waterproof structure are improved.

Description

technical field [0001] The invention relates to an engine exhaust chimney and its installation structure, and belongs to the field of auxiliary cooling equipment for internal combustion vehicles. Background technique [0002] The internal combustion rail vehicle is powered by the engine, and part of the energy of the fuel is converted into mechanical energy, and the other part is converted into heat and emitted. The heat loss form of the engine is mainly cooling water and exhaust gas, and the temperature of the exhaust gas is as high as hundreds of degrees Celsius, or even more than one thousand degrees. Although some engines have heat-insulated exhaust pipes and exhaust gas treatment systems, the exhaust gas emitted by them is still high. If no other treatment is done, it will cause great harm to personnel and other surrounding equipment. [0003] At present, internal combustion rail vehicles are generally equipped with exhaust chimneys, through which the exhaust gas is di...
