ABSTRACT For combustion engines to perform well, it is necessary that the fuel used be of high quality. Fuel quality can be analyzed through different physicochemical properties. This study presents comparisons between the values presented in literature, legislation and those obtained through experimental tests of different biodiesel samples. Biodiesel is a promising alternative of renewable energy obtained from raw material.

The properties observed in this study are:

Viscosity, density, cloud point, pour point and calorific value. The data explored by this work aims to bring solidification to the methodologies and equipment necessary for a better characterization of biodiesel.
