在柴油机上加装废气涡轮增压器，可使柴油机在尺寸不变的条件下明显提高功率，降低燃油消耗，减少汽车的废气污染。尤其在高原地区使用的发动机，因为气压低，空气稀薄，导致发动机功率下降，油耗增加。装增压器后可起到恢复功率减少油耗的作用，因此，大、中型汽车上，以装有 The installation of an exhaust gas turbocharger on a diesel engine can significantly increase the power of the diesel engine under the condition of the same size, reduce the fuel consumption and reduce the automobile exhaust gas pollution. Especially in the high altitude engine, because of low pressure, thin air, resulting in decreased engine power, fuel consumption increased. Installed turbocharger can play a role in reducing power consumption to restore power, therefore, large and medium-sized cars, to be installed
