摘要
通过对4125A柴油机不同海拔高度台架进气模拟试验结果的分析指出:为使柴油机在不同海拔高度上能维持其原有标定功率,柴油机压缩比应随海拔高度同步提高,而且,在保持压力pc不变的情况下,提高的幅度可以突破原设计范围。并导出了不同海拔高度上柴油机压缩比的计算公式。
The test's data analysis points out that diesel engine's ratedpower can be kept constantly in plateau areas of different heights above sealevel if its compression ratio is consequently raised to that, and with thepressure p? constant the compression ratio can be raised over the engine'sdesigned range. A formula for calculating the compression ratio in areas ofdifferent heights is given also.
