1.前言三菱重工业公司长期进行高速柴油机的开发,已取得了许多生产成果。最近,又开发成功了集最新技术于一身的1500～5000PS(1103～3678kW)功率等级的 SU 系列高速柴油机。该系列柴油机的缸径为240mm。6缸的 S6U 型及12缸的 S12U 型柴油机总共已生产了50余台,这两种柴油机的基本设计参数及结构已在本刊(见《国外内燃机车》1982年№2)作过介绍。
1. Foreword Mitsubishi Heavy Industries Co., Ltd. has long been engaged in the development of high-speed diesel engines and has achieved many achievements in production. Recently, SU series high-speed diesel engines with a power rating of 1500-5000 PS (1103-3678 kW) incorporating the latest technology have been successfully developed. The series of diesel engine bore is 240mm. A total of more than 50 units have been produced for the 6-cylinder S6U and 12-cylinder S12U diesel engines. The basic design parameters and construction of the two diesel engines are described in this issue (see “Foreign Diesel Locomotives”, 1982 № 2).
