    • Turbochargers comprise a compressor housing having an air inlet passage for receiving inlet airflow, an air outlet passage for passing pressurized air to an engine combustion system, and a compressor impeller rotatably disposed within the housing for receiving air from the air inlet passage, pressurizing the inlet air, and passing the pressurized air to the air outlet passage. An air flow conditioner is placed into air flow communication with the compressor housing air inlet passage, and can be disposed within an air inlet section of the compressor itself, or can be placed within a vehicle air ducting positioned upstream from the turbocharger. The air flow conditioner comprises a body that is specially designed having a plurality of air passages disposed therethrough to cause a desired flow conditioning effect on air passing through it and to the compressor to offset the onset of compressor surge during engine operation, thereby shifting the compressor operating efficiency curve to the left to broaden the operating efficiency window for the turbocharger compressor.
    • 涡轮增压器包括具有用于接收入口气流的空气入口通道的压缩机壳体,用于将加压空气传递到发动机燃烧系统的空气出口通道和可旋转地设置在壳体内的压缩机叶轮,用于从进气通道接收空气, 空气,并将加压空气通过出气通道。 空气流量调节器被放置成与压缩机壳体空气入口通道的空气流动连通,并且可以设置在压缩机本身的空气入口部分内,或者可以放置在位于涡轮增压器上游的车辆空气管道中。 空气流调节器包括一个特别设计的主体,其具有多个设置在其中的空气通道,以对通过该空气的空气和压缩机产生期望的流动调节效果,以抵消发动机运转期间压缩机喘振的开始,从而使压缩机 运行效率曲线向左扩大涡轮增压压缩机的运行效率窗口。
