The HS code-based sourcing opportunitiestrain startsMachine: Master the power source of railway travel. The train engine is the core power system of the train, which is composed of engine, transmission system and fuel system. It can convert chemical energy into mechanical energy and drive the train forward. In railway transportation, train engines are an indispensable part. It reveals to us how to use the power of science and technology to realize human long-distance travel. This article will introduce the composition, working principle, classification and future development of train engines in detail. I. The composition of the train engine The train engine is composed of the engine, the transmission system, the fuel system and other parts. Among them, the engine has cooling system, power system and other parts. 1. Engine: It is the basic power of the train, which can convert chemical energy into mechanical energy and drive the train forward. The composition of the train engine is very complex, including cylinders, pistons, crankshafts, connecting rods, rocker arms, valves, fuel injection and other components.The coordinated movement of these parts can make the engine work normally. Two. Transmission system: That is, the transmission system of the engine, which is composed of clutches, transmissions, transmission gears and other components, which are used to transmit the rotating power of the engine to the wheels to drive the train. 3. Fuel system: It is an important part of the engine. It consists of fuel tank, fuel filter, fuel pump, fuel injector and other parts, which are used to inject fuel into the engine to provide energy. II. Working principle of train engines. Internal combustion engines and steam engines are commonly used in train engines. The working principle of the internal combustion engine is to use the burning energy to drive the piston to make a reciprocating movement, so as to drive the transmission system to rotate and drive the train. The steam engine, on the other hand, uses the steam generated by water after heating to drive the piston movement, so as to promote the rotation of the transmission system and realize the train to run.In the specific process, the fuel of the train engine is injected into the combustion chamber of the internal combustion engine, and combustion occurs after mixing with air under the action of ignition. The high-temperature and high-pressure gas generated by combustion drives the piston to reciprocate, thus driving the transmission system to rotate. The working principle of the steam engine is to heat water into steam. After the pressure in the cylinder increases, the steam pushes the piston and converts thermal energy into mechanical energy, thus driving the transmission system to rotate. III. Classification of train engines can be divided into three categories according to the different fuels used by train engines: 1. Steam engine: use water vapor as the power source. Two. Diesel engine: Using diesel as fuel, its fuel efficiency is high, but the exhaust gas pollutes the environment a lot. 3. Motor: Use electricity to drive the engine. Electric-driven engines can reduce pollution, but the disadvantage is that the battery life is limited.IV. The future development of train engines. With the continuous improvement of science and technology and environmental protection awareness, the future train engines will be more intelligent and environmentally friendly. The development of solid-state battery technology and the application of new technologies such as sustainable energy will have a significant impact on train engines. In the future, we foresee that more new fuels will be applied to train engines, such as hydrogen fuel cells, and more attention will be paid to reducing pollution and improving energy efficiency. In a word, train engines are the core of modern train operation. In the future, with the advancement of technology, train engines will also be constantly optimized and improved. We believe that one day, it will become more environmentally friendly, efficient and intelligent.
