| 摘 要： | 本文通过对4125A柴油机台架模拟试验结果的计算分析指出:为使柴油机在不同海拔高度上均能维持其原有标定功率,其压缩比应随海拔高度的提高而同步提高。并根据这一思想导出了不同海拔高度地区柴油机应采用的压缩比的计算公式: εH=(P_o/P_H)1/n_(1·ε_o) 对于4125A柴油机来说,计算公式为εH=16·(100/P_H)~0.727

| Abstract: | Based on the data analysed, this paper points out that diesel engine′s rated power can be kept constant in plateau areas if its compression ratio is raised synchromously with the rising of the height above sea level. And following this thought, a formula is given for calculating the compression ratio in different plateau areas:ε_H=( P_o/P_H )~(1/n) 1·ε_o for 4125A Diesel engine, the formula is ε_=16·(100/P_H)~(0·727) |
