temperature dependence of density and viscosity of vegetable oil press machines
Temperature dependence of density and viscosity
Highlights Vegetable oils density and viscosity are higher than the ones of diesel fuel. Density and viscosity have a deep impact on the combustion of existing diesel engines. Vegetables oils density and viscosity are reduced to match diesel fuel values by heating. The dependence between viscosity and density is modeled. It allows obtaining the viscosity from the measure of the density.

The straight use of vegetable oils as fuel in diesel engines entails adjusting several physical properties such as density and viscosity. By adequately heating the vegetable oil before entering the injection system, its physical parameters can reach values very close to that of diesel fuel. Consequently, by properly adjusting the temperature of vegetable oils used as fuel, it is possible to
