EXPERIMENTAL ANALYSIS OF 20% EGR RATE ON VCR DIESEL ENGINE FUELLED WITH JATROPHA BIODIESEL BLENDS
Journal Title: International Journal of Engineering Sciences & Research Technology - Year 30, Vol 5, Issue 5
Abstract
One of the major problems facing by today’s world is “Global Warming”. Majority of the Green house gases are emitted into the atmosphere as a result of “Fossil Fuel Combustion.” Recently UNFCCC organized COP-21 in Paris, whose main agenda is to keep Global average temperature rise well below 20 C by the end of this 21st century. With inspiration to COP-21, we focus on reduction in greenhouse gas emissions from the Diesel engines by fueling the engine with Jatropha Biodiesel blends. Research work shows that Jatropha biodiesel fuelled engines emit less CO2, HC and smoke emissions but higher NOx emissions than conventional diesel fuelled engines. The objective of this work is to reduce NOx emissions from jatropha biodiesel fueled CI engine with cooled Exhaust Gas Recirculation(EGR) technique without compromising at the performance.Tests were conducted on A VCR, single-cylinder, water cooled, constant speed(N=1500rpm),direct injection diesel engine by operating with pure diesel and Jatropha biodiesel blend JBD20 at a fixed compression ratio of 17.5:1 with and without EGR(E20).The performance, combustion and Emission parameters were evaluated experimentally.The Application of EGR with Jatropha biodiesel results in reduction of NOx, HC, CO2 and CO emissions without any significant upsurge in smoke emissions.
