    • A method for diagnosing a turbocharger (10) includes disconnecting the compressor outlet conduit (26) so that the engine (12) is naturally aspirated and using the engine to drive the turbine (14) of the turbocharger. The compressor outlet conduit (26) has a restriction (28) to create a backpressure which is measured along with the inlet pressure, barometric pressure and ambient temperature. The flow rate is determined and compared to acceptable parameters from a map data provided by a turbocharger manufacturer to diagnose if the turbocharger is operating within the acceptable parameters.
    • 用于诊断涡轮增压器(10)的方法包括断开压缩机出口管道(26),使得发动机(12)被自然地吸入并且使用发动机来驱动涡轮增压器的涡轮机(14)。 压缩机出口管道(26)具有限制(28)以产生背压,其与入口压力,大气压力和环境温度一起测量。 确定流量并根据涡轮增压器制造商提供的地图数据与可接受的参数进行比较,以诊断涡轮增压器是否在可接受的参数范围内运行。
