Effect of Cooled EGR Technique on Performance and Emissions of CRDI Engine Operated with Biodiesel Blends
Journal Title: International Journal of Mechanical and Production Engineering Research and Development (IJMPERD ) - Year 2019, Vol 9, Issue 4
Abstract
Hazardous pollutants and limited sources of fossil fuels made power dependent sectors to focus on alternative sources. However, complete replacement is still constrained and challenging. Attempts to assure complete replacement were more or less fulfilled by biodiesels. In this article, trials made on EGR associated single cylinder CRDI engine with blends of Jatropha and Rice-bran biodiesels are discussed. Set of readings obtained under the split injection system of mass 10% pilot fuel and 90% main fuel maintained at 300 bars with dwell of 10o and 15% of cold EGR are examined. Results obtained show, brake thermal efficiency is higher at peak load for RJD-II sample than RJD-I sample, whereas specific fuel consumption is same. Sample RJD-I has indicated highest break mean effective pressure at full load which influenced mechanical efficiency. Remarkable changes observed in emissions indicate 11.7% and 16.6% reduction in CO for RJD-I and RJD-II, respectively. NOx discharge reduced up to 5.5% and 7.7% for RJD-I and RJD-II, respectively. CO2 products are 6.6% and 8.6% higher for RJD-I and RJD-II respectively than diesel.
