The Effect of Variable Compression Ratio on Performance and Emission Characteristics of Diesel Engine Fuelled With Blends of Diethyl Ether, Linseed Oil Biodiesel and Diesel 2015-01-1936

The aim of present work is to investigate the performance and emission characteristics of a four stroke, single cylinder variable compression ratio engine fuelled with blends of diethyl ether, linseed oil methyl ester and neat diesel. In the experiment content of diethyl ether kept constant as 5% by volume for all fuel samples whereas linseed methyl ester biodiesel content was varied as 10%, 15% and 20% by volume. The different fuel samples DLD15, DLD20 and DLD25 with neat standard diesel. Experiment tests were performed with engine speed 1500 rpm and variable compression ratio 16, 17 and 18 at different load conditions. The effect of blends and compression ratio on different performance parameters viz. brake thermal efficiency (BTE), brake specific fuel consumption (BSFC), and exhaust gas temperature along with emissions CO, CO2, HC and NOx, were investigated. Results showed that DLD20 and DLD25 exhibited the prominent engine performance and exhaust emissions compared to diesel fuel.
