苏联斯维尔德洛夫斯克涡轮机和发动机联合制造厂扩大了210/210mm现代柴油机的开发和生产。8DM-21系列中的新型8缸机的平均有效压力为13.1～18.2巴,曲轴转速为1200～1500r/min,较好地满足了广大用户极端严格的各种需要。该机在其尺寸档次中功率最大,是专门为移动式电站和重载卡车(最大载重180?)设计的。在1500r/min时的标定功率达1324kW,燃油消耗率为205g/kWh,不高于标定燃油消耗率的0.5％,比重量低于4.5kg/kW,保用寿命40000h(大修期)。本文着重介绍这种现代柴油机开发工作的主要成果。
Soviet Union Sverdlovsk Turbines and Engines Expands Development and Production of 210 / 210mm Modern Diesel Engines. The average effective pressure of the new 8-cylinder machine in the 8DM-21 series ranges from 13.1 to 18.2 bar with a crankshaft speed of 1200 to 1500 r / min, which satisfactorily meets the extremely demanding needs of the vast majority of users. The aircraft in its size grade power maximum, specifically for mobile power plants and heavy-duty trucks (maximum load 180?) Design. The calibration power at 1500 r / min reaches 1324 kW, the fuel consumption rate is 205 g / kWh, not higher than 0.5% of the rated fuel consumption rate, the specific weight is lower than 4.5 kg / kW and the service life is 40,000 h (overhaul period). This article highlights the major achievements of this modern diesel engine development.
