增压柴油机要求在运行线上增压器有高的总效率,这就要求所有气流通道有合适的尺寸关系和各流道均只有低的流动阻力.当增压压力提高时,要求所有叶道内均只有亚临界流,于是要求严格控制静叶与动叶的截面积比,以求有最佳的反动度,作者认为在此应同时计及 A turbocharged diesel engine requires a high overall efficiency of the supercharger on the line of operation, which requires that all gas flow passages have a suitable dimensional relationship and that each flow passage has only low flow resistance.When the supercharging pressure increases, all of the inside of the passages Only subcritical flow, so require strict control of vane and bucket cross-sectional area ratio, in order to have the best reaction, the author believes that this should be taken into account
