Performance Emission of N-Octanol - Biodiesel Blend in Diesel Engine

Abstract

From last three decades scientists have explored the alternative fuel to substitute petroleum diesel for CI engine. One of the promising alternative fuel is biodiesel which has potential to substitute the conventional fossil fuels in near future. In the present study the author has considered Karanja biodiesel blended with n-octanol as an oxygenated blend to evaluate the performance, emissions and combustion features of diesel engine. The obtained results were improved relative to mineral diesel. The increment of BTE by 10.40% and decrement of BSEC by 13.20% were observed by using the blend KME80O20compared with neat JME at full load . Significant reduction in emission of HC-15.68%, CO-44.73%, smoke opacity -19.31%compared than diesel and reduction in NOx 3.04 % compare to neat KME were observed for KME80O20.This signifies improved combustion characteristics while utilizing n-octanol up to 20% as blend with KME in CI engine.
