Experimental Investigation on CI Engine using Alcohol Fumigation Method for Emission Reduction

Currently any internal combustion engine requires high performance and reduced emissions. The use of alternative fuels in CI engine that are produced from non-petroleum resources is suggested as one of the promising methods for improving performance and reduction emissions. This Fuels are suggested by researchers are alcohols, ethers, vegetable oils and bio-diesel etc. Alcohol is oxygenated fuel which promising fuel characteristic reduction in emission that have for better combustion in C.I engine and has low viscosity than diesel fuel which makes the alcohol easily to be injected and atomized and mixed with air. There are several techniques available for using alcohol as a fuel in CI engine like Alcohol fumigation, Alcohol-diesel blend, emulsification and duel injection in which problem associated is stability of fuel which can be overcome by alcohol fumigation. Alcohol fumigation is a dual fuel engine operation technique in which alcohol fuels are premixed with intake air. Alcohol fumigation is getting high demand as an effective measure to reduce pollutant emission from CI engine vehicles. The aim of this study is to identify the potential use of alcohol in fumigation mode on diesel engine. This study investigates the exhaust emissions and exhaust emission characteristics of CI engine using fumigated alcohol. Find out optimum percentage of the premixing alcohol.
