涡轮增压器能在发动机排量不变的情况下，提高其动力性能，降低尾气排放，最初主要用于柴油发动机。最近，汽油发动机也越来越多地安装了涡轮增压器。Turbo，即涡轮增压，简称T，最早时候由瑞典的萨博（SAAB）汽车公司应用于汽车领域。现在很多人都知道了，涡轮增压简称TURBO，如果在轿车尾部看到TURBO或者T，即表明该车采用的发动机是涡轮增压发动机。这些汽车的发动机工作，是靠燃料在发动机气缸内燃烧作功，从而对外输出功率。在发动机排量一定的情况下，若想提高发动机的输出功率，最有效的方法就是多提供燃料燃烧。然而，向气缸内多提供燃料容易做到，但要提供足够量的空气以支持燃料完全燃烧，靠传统的发动机进气系统是很难完成的。

Turbochargers can improve engines’power performance and reduce exhaust emissions without changing their were mainly used in diesel enginesfirstly .Turbo, namely the turbocharging, is called T, most early time (SAAB) the Car company applies by Sweden's Sabo in the automobile domain. Many people have known now, the turbocharging is called TURBO, if saw in the passenger vehicle rear part TURBO or T, namely indicated this vehicle uses the engine is the turbocharging engine. These automobile's engine work, is makes the merit depending on the fuel in the engine cylinder internal combustion, thus foreign output. In engine capacity certain situation, if wants to raise engine's output, the most effective method provides the fuel burning much. However, provides the fuel to the air cylinder in easily to do, but must provide the enough quantity the air to support the fuel to burn completely, is very difficult to complete depending on the traditional engine air intake system. 损咕涮弛取吝拆揠浸粳肘勿澌粽
