摘　　要：文章主要论及柴油机功率曲线及其最主要的2个参数:转速和燃油齿条位置(油门),在论述功率曲线内涵的同时,作者给出了一种供航行中船舶估算主机功率和燃油耗率的方法,并示出了供燃油耗率估算用的算式和图表。为使估算值保持足够的精度,根据柴油机技术并结合数学处理手段,文章给出并介绍了修整方法。根据文章给出的估算方法,很容易找到航行最佳经济工况点。This paper is mainly dealt with the power curve and two parameters---engine speed and fuel pump rack position. While explaining the meaning and purpose of power curve, the author tries to give a method to be used for power estimation of voyaging vessels and to present some formulas and charts for estimation of specific fuel consumption simultaneously. In order to keep the accuracy of what has been estimated, some countermeasures based on a diesel engine' s technology in combination with mathematical treatment have been introduced. According to them an economic navigation condition can easily be picked up.
