Bio-Based Hydraulic Fluids and the Influence of Hydraulic Oil Viscosity on the Efficiency of Mobile Machinery

Leakage of hydraulic oils causes long-term damage to the environment. Every year, a significant amount oil is released into environment through accidents and leakages. Biohydraulic minimize risk environmental due their biodegradability lack toxicity. Mobile machines offer great substitution potential for biohydraulic oils. The majority are operated with mineral Furthermore, in view decreasing energy resources rising CO2 emissions, there strong interest reducing fuel consumption mobile machines. Triggered by this trend, power density systems components continue increase. Resulting, used fluid subject greater thermal stress system fluids becoming increasingly important. properties, regarding viscosity temperature dependency. Therefore, content article consider influence oil’s on efficiency crawler excavator. For purpose, experimental tests discussed related losses excavators using oil. A hypothesis about dependency rheological properties system’s formulated.
