Simulation Techniques for Improving the Fuel Efficiency of Hydraulic Excavators
نویسندگان
چکیده
Simulation techniques to reduce the fuel consumption in hydraulic excavators are presented in three categories: first, a strongly non-linear dynamic simulation technique for a coupling system with a non-linear hydraulic system and a linkage system; second, a technique for evaluating fuel consumption in the engine when the engine powers the hydraulic pump in a digging operation performed by a hydraulic excavator in real time; and, finally, a dynamic simulation technique for evaluating the efficiency of a hybrid system consisting of power electronics equipment, electric-hydraulic equipment, and a linkage system.

Hydrogen fuel is the cleanest fuel available. This fuel can be used as an additive in the diesel engine. Diesel engines have the advantages of strong power, high thermal efficiency and low fuel costs. There have been extensive studies on the use of hydrogen fuel in diesel engines in recent years. However, the simultaneous effect of using gaseous hydrogen fuel and changing injection strategy nee...
متن کاملThermo-Hydraulic Investigation of Nanofluid as a Coolant in VVER-440 Fuel Rod Bundle
The main purpose of this study is to perform numerical simulation of nanofluids as the coolant in VVER-440 fuel rod bundle. The fuel rod bundle contains 60 fuel rods with length of 960 mm and 4 spacer grids. In VVER-440 fuel rod bundle the coolant fluid (water) is in high pressure and temperature condition. In the present Thermo-hydraulic simulation, water-AL2O3 nanofluids containing various vo...
