摘　　要：在挖掘机日常作业时,柴油机在负载突增、高原作业等情形下,因瞬态喷油量增加,或实际进气量不足,会致使燃料燃烧不充分,进而易使排放烟度升高。文章提出一种液压泵最大吸收功率控制法,该方法依据整机反馈信息,修正液压泵最大吸收功率,让液压端最大吸收功率始终契合柴油机的最大功率输出能力,减少挖掘机工作时烟度超限的情况。In the daily operation of excavator,diesel engine will not burn fully due to the increase of transient fuel injection or insufficient actual air intake in the case of sudden load increase and plateau operation,which will easily increase the emission smoke.This paper presents a control method of maximum absorbed power of hydraulic pump,which modifies the maximum absorbed power of hydraulic pump according to the feedback information of the whole machine,so that the maximum absorbed power of hydraulic end always conforms to the maximum power output capacity of diesel engine,and reduces the smoke overlimit during the work of excavator.
