摘　　要：深入分析当前挖掘机电子节能控制技术在节能原理上存在的缺陷,提出柴油机恒阻力矩制的电子节能原理。该节能控制原理从理论上消除功率匹配不当的功率损失,实现柴油机恒阻力矩、恒速、恒功率运行,且输出功率完全被液压泵吸收,实现真正意义上的节能控制。Defects in energy-saving principle of current electronic energy-saving control technology for excavators are analyzed and an electronic energy-saving principle of constant resisting torque control of engine is presented. In the principle, power loss due to inadequate power match is eliminated theoretically so that the engine can realize operation in constant resisting torque, constant speed and constant power, the output power is completely absorbed by hydraulic pump so real energy- saving control is realized.

关 键 词：挖掘机 柴油机 节能控制
