本文介绍ND_5机车7FDL柴油机在进行出厂试验整定功率时,根据当时的大气和燃油条件进行功率修正的方法。文中给出了修正系数的公式和功率修正系数图。文中指出:7FDL柴油机的调速器为机电联合式的,每给定一个转速,就有一个固定的喷油泵齿条伸出量与之对应,因而修正功率不仅与大气条件有关,而且还与给定的燃油条件有关。
This article describes the ND_5 locomotive 7FDL diesel engine in the factory test set power, according to the prevailing atmospheric and fuel conditions for power correction method. The paper gives the formula of correction coefficient and power correction coefficient. The article states: 7FDL diesel governor for the electromechanical joint type, given a speed, there is a fixed injection rack gear sticking out corresponds to it, so the correction of power not only with the atmospheric conditions, but also with the Set the fuel conditions.
