| Abstract: | This passage puts forward a new control method in hydraulic excavator in order to save energy--the correspond control between constant power and variable power. According to the variety and complexity of loading we can use controller to control the engine and the pump to make them matching the loading. In this method the power of the engine can be used as much as possible and the engine can work on it's excellent point to increase the usage of the fuel and the efficiency of the whole machine. |
