本文介绍了新型曼恩32/36四冲程柴油机,其单缸功率为370千瓦(500马力),转速750转/分。该机型的研制工作考虑了当前形势对柴油机的特别要求,即:在燃用劣质油时,燃油消耗率要低,环境污染小和可靠性高。文中介绍了研制过程并讨论了测量结果。还提供了主要的诸如喷油系统、压缩比和增压等方面的最佳设计参数。对于各种燃烧室形式对零部件温度的影响及低负荷下柴油机的工况也作了较为详细的描述。
This article describes the new MAN 32/36 four-stroke diesel engine with a single-cylinder power rating of 370 kW (500 hp) and a speed of 750 rpm. The development of this model took into account the special requirements of the current situation on the diesel engine, that is, when using inferior oil, the fuel consumption rate is low, the environmental pollution is small and the reliability is high. The article describes the development process and discusses the measurement results. It also provides the best design parameters such as fuel injection system, compression ratio and boost. The influence of various combustion chamber forms on the temperature of components and the working condition of diesel engine under low load are also described in detail.
