继开发成功MET-SC增压器并达到最高效率72.5％之后,三菱又开发成功大型径流涡轮增压器MET-SR系列(见图)。它的基本结构继承了SC-系列,例如不冷却的涡轮壳体、内置滑动轴承、和在轴承架中置有高压油腔,可替代滑动轴承系统必需的高位油箱。与SC-系列不同的在于采用径流涡轮。而且这种径流涡轮是大尺寸 Following the successful development of the MET-SC supercharger and its maximum efficiency of 72.5%, Mitsubishi developed the MET-SR series of large-scale radial turbochargers (see photo). Its basic structure inherits the SC-series, such as a non-cooled turbine housing, built-in plain bearings, and a high-pressure oil chamber in the bearing housing to replace the high level fuel tank required for a plain bearing system. The difference with the SC-series is the use of radial turbines. And this run-off turbine is large size
