Abstract
Nitrogen dioxide (NO2) is the ubiquitous chemical structure of NOx in the ambience that is initiated by anthropogenic (human) acts. NO2 is also reacts in the surrounding to result in ozone (O3) and the main culprits for acid rain. Captured proportion of NOx by moisture forms acid rain. Acid rain severely affects certain ecosystems. The facts mentioned indicate necessity to reduce NOx pollution. When any of these oxides disintegrate in H2O and breakup, they result in nitric acid (HNO3) or nitrous acid (HNO2). Automobiles is one of the major sources of the NOx that is emitted. Here in this experimental based research effort has been made to reduce emissions of NOx and CO emitted by the diesel based engine powered by Madhuca longifolia as a biodiesel blended with diesel (B10, B20, B30) by injecting water after exhaust gas manifold to get reaction so as oxides disintegrate in H2O and breakup, they result in nitric acid (HNO3) or nitrous acid (HNO2). Experimental work conducted on Mono-cylinder CRDI engine. Trials were taken with different blends of Madhuca longifolia by setting CR 15,16, 17 and 18 with water injected at 3 different mass flow rates (38.7, 82.7, 130.4 CC/min). Results shows average reduction in NOx by 7.89%, 12.26%, and 17.73% respectively.
