Reduction of NO _X Emission Using EGR In Biodiesel Fueled Engine With Ether Based Additives

This project aims to reduce the NOx emission in the diesel engine exhaust and to improve the performance of the engine. The literary survey reveals that using fuel additives, which oxygenate the fuel, reduces the emissions. In these oxygenates, ethers behave better than alcohols. In this present work, some of these ethers were selected which were not much tried and details were not much known. Diethylene Glycol Mono Methyl Ether and Diethylene Glycol Monobutyl Ether are the two additives selected for this work. These additives are added with biodiesel (POME) in various proportions and it reduces the NO_x emission. Initially, the engine was run by diesel, and then by biodiesel and biodiesel plus additives. The performance test was carried out in a single cylinder Kirloskar AV-I engine with and without EGR. This engine is coupled with electrical loading device. The use of biodiesel in conventional diesel engines results in substantial reduction in emission of unburned hydrocarbons, carbon monoxide and particulate. This review focuses on performance and emission of biodiesel in CI engines, and combustion analysis.
