Abstract
Constant lowering of natural reserves of fossil fuels as well as continuous increasing of its exploitation costs influences more intensive researching in finding alternative energy recourses that are able to decrease an import dependent of expensive raw oil and its products from one side and give contribution to decreasing toxic emission as a product of combustion process. As result of this consideration majority of developed European countries endeavor to fulfill proposals of the European parliament and the Council for promotion bio fuels to substitute petroleum and diesel fuels with bio fuels in proportion of 5.75% of their total sold amount, measured by its energy content, by the year 2010.
In the paper usage of bio fuels in IC diesel engines for mobile applications is considered. Accent is given on combustion processes of so called biodiesel fuel, as a full alternative for classical diesel fuel, as well as their blends, where important role has beginning, character of heat release and duration of combustion process. Calculation results of relevant combustion parameters for the used fuels and comparison with appropriate parameters of combustion processes with fossil origin based diesel fuel are presented. Verification of the calculation results where carried out through tests made on one diesel engine.
Keywords
