Effects of Dual-fuel at Different Engine Parameters

Abstract

Rapid depletion of fossil fuels is urgently demanding an extensive research work to find out the viable alternative fuel for meeting sustainable energy demand without any environmental impact. looking at the twenty first century, it seems that cleaner and greener form of energy in complete congruence with environment are the only hope for a sustainable future.In the current investigation CNG is used with Jatropha oil methyl ester (JOME) in a dual fuel mode for complete combustion of charge present inside the combustion chamber, and for the reduction of emissions associated with CI engines. The engine trials were conducted on a stationary air cooled constant speed agricultural direct injection diesel engine by increasing load from 0-100%.The effects of the pilot charge on various performance and emission characteristics were evaluated on all range of load. While comparing the results with diesel an increment in Brake Thermal Efficiency (BTE) and reduction in the emissions i.e. CO, HC, smoke were found with the dual fuel mode of CNG-JOME in CI engine.
