Formulation and Production of Bio-Hydraulic Fluid as an Alternative to Mineralfluids for Automobiles.
Journal Title: American journal of Engineering Research - Year 2016, Vol 5, Issue 10
Abstract
This work formulated and produced bio-hydraulic brake fluid, as an alternative tomineral fluidsDOT 3, 4.and 5.1.Glycerolwas used as its base substance and various lubricants and additives were added to impart the desired performance characteristics to the fluid. The bio-fluid was subjected to some major fluid property tests, pour point, boiling points, freezing point and dynamic viscosities within a temperature range of 30°C to 100°C. Its mineral-based fluid counterpart was also tested of same properties. The results indicated that there is close similarity in these physio-chemical properties. The bio-based hydraulic fluid has its pour, boiling, freezing points, and viscosities as -44.9°C, 326oC, -48.2°C, and 0.009 kg/ms to 0.001 kg/ms for the tested temperature range, respectively as against -35°C, 205oC, -40°C and 0.007 kg/ms to 0.001 kg/ms range, respectively for mineral hydraulic brake fluid. This close correlation of properties which majorly determine this suitability as hydraulic fluid offers bio-fluid with glycerol as its base substance a good alternative to the conventional mineral based hydraulic fluid.
