关 键 词：hydraulic excavator variable power power matching energy saving 

摘      要：正According to the variety and complexity of the load,a method of the matching control between constant power and variable power is put out based on the analysis of the diesel *** energy saving controller is used in this paper to make the diesel and the pump work according to the *** the end, experiment is produced on the hydraulic excavator. From the experimental result,the fluctuant bound is dwindled,the usage ratio of the fuel and the efficiency of the whole machine are *** can get about 5% of fuel saving by this control strategy.
