The influence of some biofuel operating properties

Abstract

The scientific research reflected in this study aimed at determining the operating properties of biodiesel (B100) and biodiesel-diesel blends (B20, B50). The goal was achieved by using the equipment of the Chemotology and Exploitation Materials experimental research laboratory of the Technical University of Moldova. Based on the results presented in this paper, the analysis of the experimental research was carried out, where the operating properties of biodiesel (B100) and biodiesel-diesel mixtures (B20, B50) for fueling compression ignition engines were determined. Therefore, the obtained values of the flash point for biofuels are higher in relation to that of diesel: for B100- by 64 °C, for B50- by 15 °C, for B20- by 3 °C, a fact that serves as proof, that the studied biofuels are more stable in terms of fire safety. At the same time, the values of the freezing temperature indicate the fact that engines powered by biofuels can operate in environmental conditions with temperatures higher than -12 ºC.
