Energy characterization of biodiesel obtained by transesterification from organic matter and its influence as an additive on the mechanical performance of the engine of the mazda bt-50 vehicle

Abstract

The research work obtained biodiesel by using beef fat as raw material, which in our environment is considered as waste, taking advantage of its energy potential through a transesterification process, using sodium hydroxide as a catalyst, which is a substance in aqueous solution "lye"; producing 55% of the raw material in biodiesel due to the chemical reaction that divides the beef tallow into glycerin and products derived from the reaction, in addition to the losses in the washing and drying processes. Blends were made at B25, B40, B55, B70 and B85 % with premium diesel characterized by physical-chemical tests that determine levels of sulfur, water, cloud point, cetane index, copper foil corrosion, density, viscosity, flash point, PH level and calorific value under NTE INEN and ASTM standards that will establish the best samples; to use them the internal combustion engine of the Mazda BT-50 truck, determining the impact on the mechanical performance of the test vehicle such as: torque, power, consumption and opacity to analyze and compare based on nominal values of the vehicle and national regulations in force establishing which is the most optimal sample for use.
