Diesel engines exhausting gaseous emission and particulate matter have long been regarded as one of the major air pollution sources, particularly in metropolitan areas, and have been a source of serious public concern for a long time. There has been numerous research in the field of reduction of these pollutants since diesel engines came to major use. Major emissions from a diesel engine are NOx, SOx, CO and particulate matter (PM).amongst these pollutants CO and Sox and some quantity of particulate matters are reduced by some after treatment devices. Also NOx emissions are reduced by selective catalytic reduction, exhaust gas recirculation. In this work, the experiment was carried out on twin cylinder diesel engine fuelled with water emulsified diesel and fly ash as an additive. The test is carried out at constant speed and varying the load condition and investigate the performance and emission characteristics of the engine. Brake specific fuel consumption is increased by 3.33% and 5.43%. and NOX emission is reduced by 11.87% and 15% respectively, when addition of 5% and 10% water in diesel. Also with the addition of 3% and 6% fly-ash in 5% and 10% water diesel emulsion. Brake specific fuel consumption is increased by 6.27%, 7.91%, 5.79% and 8.21%, also Co emission was increases by 22.33%, 12.5%, 36.36% and 22.22% respectively when results comparing with diesel. The Brake thermal efficiency was increased by 4.39% when addition of 10% water in diesel and also with addition of 3% and 6% fly-ash in 10% water diesel emulsion there is 3.97% and 1.11%. Brake thermal efficiency increases as compare to diesel.
