[0002] A train refers to a vehicle that runs on railway tracks, usually composed of multiple carriages. It is one of the important modern means of transportation for humans. When a traditional coal-fired train is working, a turbo train supercharger is needed to increase the air intake of the combustion chamber or engine so that the fuel can be fully burned.

[0003] In order to improve the energy utilization efficiency of existing trains, the exhaust gas generated by combustion needs to be connected to the intake pipe of the turbo train supercharger, so that the exhaust gas and air are mixed and enter the combustion chamber or the engine to utilize the combustibles in the exhaust gas. Although this improves the energy utilization efficiency, the operating temperature of the turbo train supercharger is too high due to the excessively high exhaust temperature, so that the turbo train supercharger cannot work for a long time, and the stability of the turbo train supercharger is poor, making it inconvenient to use.
