高平均有效压力的大型二冲程柴油机的增压系统由效率极高的涡轮增压器组成,通常还包括一个动力涡轮。高平均有效压力的四冲程柴油机要求相当高的压气机压比。本文介绍瑞士巴登ABB涡轮机械系统部为满足涡轮增压柴油机发展的需要而研制的BBC涡轮增压器和动力涡轮。
The supercharged system for a large two-stroke diesel engine with high average effective pressure consists of an extremely efficient turbocharger, often including a power turbine. Four-stroke diesel engines with high average effective pressure require quite high compressor pressure ratios. This article describes the BBC turbochargers and power turbines developed by the ABB Turbine Systems Division in Baden-Württemberg to meet the needs of turbocharged diesel engines.
