Emission Properties and Performance Characteristics of Jatropha Curcas L. and Spirulina Platensis Microalgae oil-based biodiesel in diesel Machines

Abstract

Abstract The article aims at investigating the performance of diesel engine and emission properties of non-eatable oils methyl esters of J. Curcas L. and Spirulina Platensis microalgae based biodiesel in diesel engines (DE). Kirloskar Six cylinder diesel engine was the test engine used to ascertain the level of Break Power (BP) and BSFC and the Emissions of Carbon (IV) Oxide (CO2), Hydrocarbons (HC), Carbon monoxide (CO) and Nitrogen Dioxide (NOX). Different ratios of biodiesel were mixed with diesel fuels using 10.0 and 20.0 percent by volume of methyl esters with the diesel fuels for example AB10 (10% by vol. Biodiesel and 90% by vol. Diesel fuels), JB10, AB20 and JB20 respectively. However, the procedures of the experiment was in agreement with EN 14214 and ASTM D6751 procedures. The biodiesel fuel samples used decreases the brake power (BP) and increase brake-specific fuel consumption (BSFC) when compared to conventional oils. Results from emission indicates that the blended biodiesel reduces CO, CO2 and HC Emission and causes an increase in NOX emission. Since AB10 gives lesser emissions, it is a better option for diesel fuels in engines that are not modified to minimize exhaust releases in the environment.
