柴油发电机组原理  Principle of diesel generator set

      简而言之，就是柴油发电机驱动发电机运转。

在汽缸内，经过空气滤清器过滤后的洁净空气与喷油嘴喷射出的高压雾化柴油充分混合，在活塞上行的挤压下，体积缩小，温度迅速升高，达到柴油的燃点。柴油被点燃，混合气体剧烈燃烧，体积迅速膨胀，推动活塞下行，称为‘作功’。各汽缸按一定顺序依次作功，作用在活塞上的推力经过连杆变成了推动曲轴转动的力量，从而带动曲轴旋转。将无刷同步交流发电机与柴油发电机曲轴同轴安装，就可以利用柴油发电机的旋转带动发电机的转子，利用‘电磁感应’原理，发电机就会输出感应电动势，经闭合的负载回路就能产生电流。

         这里只描述发电机组最基本的工作原理。要想得到可使用的、稳定的电力输出，还需要一系列的柴油发电机和发电机控制、保护器件和回路

       In short, it is a diesel generator that drives the generator to operate.

        In the cylinder, the clean air filtered by the air filter is fully mixed with the high-pressure atomized diesel injected by the fuel injector. Under the upward pressure of the piston, the volume shrinks and the temperature rapidly rises, reaching the ignition point of diesel. Diesel is ignited, and the mixed gas burns violently, rapidly expanding in volume and pushing the piston downwards, which is called 'work'. Each cylinder works in a certain order, and the thrust acting on the piston is converted into a force that drives the crankshaft to rotate through the connecting rod, thereby driving the crankshaft to rotate. By installing the brushless synchronous AC generator coaxially with the crankshaft of the diesel generator, the rotation of the diesel generator can be used to drive the rotor of the generator. Using the principle of 'electromagnetic induction', the generator will output induced electromotive force, which can generate current through a closed load circuit.

       This only describes the most basic working principle of the generator set. To obtain usable and stable power output, a series of diesel generators, generator control, protection devices, and circuits are also required
