A kind of smoke exhaust device for internal combustion motor train and internal combustion motor train

Abstract

The invention relates to a smoke exhaust device for a diesel train set and a diesel train set, including a diesel engine installed under the train, the diesel engine is connected to a smoke exhaust pipe, and a car body formed by a cavity penetrating the car body up and down is arranged on the car body passage, the exhaust pipe is installed through the passage of the vehicle body from the bottom of the vehicle to the roof, the exhaust port of the exhaust pipe is arranged above the roof panel, and the inner wall of the passage of the vehicle body and the exhaust pipe There are communication gaps through the upper and lower walls between the outer walls. The present invention guides the exhaust gas of the diesel engine to the roof for discharge, which not only has a simple overall structure and is convenient for installation, but also effectively improves the influence of the exhaust gas of the diesel engine on the environment of the station platform and the air quality inside the passenger compartment during the stop of the EMU. At the same time, through the setting of the flow gap, It plays a better role in heat insulation and cooling, and eliminates the thermal influence of the high-temperature smoke exhaust pipe on the car body.

Description

technical field [0001] The invention belongs to the technical field of internal combustion multiple trains, and in particular relates to a smoke exhaust device for internal combustion multiple trains. Background technique [0002] In the prior art, an EMU driven by an internal combustion engine is mainly composed of a diesel locomotive + a passenger car compartment, and the traction device, diesel engine and other power devices and power traction devices are jointly installed on the diesel locomotive. This method is currently widely used in countries all over the world. However, this arrangement takes up a lot of space, which is not conducive to reducing the axle load and effectively utilizing the passenger space on the vehicle. For this reason, the prior art provides a scheme of distributing power integration systems such as diesel engines under the vehicle, highly integrating the internal combustion power transmission system, and dispersing and hanging them under the vehic...

AI Technical Summary

Problems solved by technology

[0003] For centralized power internal combustion multiple units, the exhaust pipe of the diesel engine directly passes through the roof panel of the locomotive to exhaust smoke from above the roof, but for decentralized power internal combustion multiple units with diesel engines and other power integration systems installed under the vehicle, there is The disadvantage of exhaust gas from diesel engines being directly discharged to the station platform during the station is that when the vehicle stops, it will have a great impact on the air environment of the platform
