EFFECT OF DOPING DIESEL OIL WITH METHYL ESTERS ON PHYSICOCHEMICAL PROPERTIES OF THE OBTAINED FUEL, IN THE ASPECT OF ITS EXPLOITATION POTENTIAL
Journal Title: Journal of KONES - Year 2014, Vol 21, Issue 4
Abstract
Vision of depletion of fossil fuels and associated with the usage negative impact on the environment, resulted in increased interest in finding alternative sources of materials, which may be used to power internal combustion engines. Usage of biofuels to power diesel engines offers a wide range of benefits for the user and also the environment. Biodiesel interpreted as fatty acid methyl esters obtained from renewable resources by transesterification of fatty acids, can be used as an alternative fuel to petro-diesel, as well as pure fuel or as an additive to diesel. Due to its “renewable” origin and characteristics, such as biodegradability or lower emissions of toxic components in the exhaust gases, biodiesel is a highly attractive alternative to fossil fuels. Although it is possible to feed CI engines with pure biodiesel, many researchers points lot of, operational and related to combustion processes, problems with usage 100% biodiesel in modern engines, equipped with technologically advanced injection systems. In order to maintain best performance properties, a number of standards have been made. These standards clearly define the parameters that biodiesel must met to be used for powering CI engines.This paper presents comprehensive analysis of properties of pure biodiesel and its mixtures with diesel in terms of usage to feed modern CI engines. Also procedure of obtaining biodiesel, laboratory equipment and procedures were presented. A number of key parameters (density, viscosity, acid value, cold filter plugging point, oxidation stability, sulphur content and flash point) were examined for pure biodiesel and its mixtures. Tests were performed according to procedures outlined in the PN-EN 14214. Based on the results the utility of biofuels and their mixtures was presumed for use in compression ignition engines.
