涡轮增压器的工作原理

A significant difference between a turbocharged diesel engine and a traditional naturally aspirated gasoline engine isthe air entering a diesel engine is compressed before the fuel is injected.涡轮增压器对柴油机的功率输出和效率至关重要。

It is the job of the turbocharger to compress more air flowing into the engine's cylinder.当空气被压缩时,氧分子被压缩得更紧密。空气的增加意味着相同尺寸的自然吸气发动机可以增加更多的燃油。This then generates increased mechanical power and overall efficiency improvement of the combustion process.Therefore,涡轮增压发动机的发动机尺寸可以减小,从而获得更好的包装,重量减轻的好处和整体改善的燃油经济性。

涡轮增压器是如何工作的?

A turbocharger is made up of two main sections: the turbine and the compressor.涡轮机包括涡轮轮(1)以及涡轮壳体(2).涡轮壳体的工作是引导exhaust gas (3)进入涡轮。废气产生的能量使涡轮转动,然后气体通过排气口面积(4).

压缩机还包括两个部分:compressor wheel (5)以及压缩机壳体(6).压缩机的作用方式与涡轮相反。压缩机叶轮通过锻钢轴(7),当涡轮转动压缩机叶轮时,高速旋转吸入空气并压缩空气。The compressor housing then converts the high-velocity,低压气流进入高压,low-velocity air stream through a process called diffusion.The压缩空气(8)is pushed into the engine,allowing the engine to burn more fuel to produce more power.
