"How A Train Engine Work"

A diesel-electric train can tow dozens of carriages With such a powerful traction force how does its power system work Note that this is a twelve-cylinder twin-turbo four-stroke diesel engine Let's compare it to a person Each cylinder corresponds to an injection nozzle which injects diesel into the corresponding cylinder Under the engine is a large capacity fuel tank with a refueling capacity of more than 20000 liters Additionally a lubricating oil tank oil filter and fuel filter are installed next to the engine This 12 cylinder engine features 2 turbochargers to provide more air to the engine Adjacent to the turbocharger there is an air cooler that cools the compressed air Cooled air is more powerful allowing more air to enter the engine The air enters the large turbocharger from the air inlets on both sides then passes through the small turbocharger and finally enters the engine after being cooled down by the cooler As the engine rotates it drives a large alternator to generate electricity This electricity in turn powers 6 traction engines connected to the axle providing the necessary force to move the train
