Abstract : Modification of fuel properties to reduce emissions have become imperative due to enforced regulations. Experimental studies conducted earlier indicate that reduction of pollutants like HC, CO is possible using oxygenated fuel additives such as ethers, alcohols and carbonates. Anti-oxidant additives are used to reduce the NOx in the exhaust emission. The present work investigates the influence of oxygenated fuel additive to emissions of diesel fuel blended with synthetic oxygenated compound such as Diphenyl ether (DPE) along with an anti oxidant additive Diethyl amine (DEA). Diesel fuel blends which contain DPE of volume 10% and 15% of diesel and 5% of DEA were prepared. The influence of these blends on emission characteristics were investigated. These blends were tested at constant speed under various loading conditions. The results indicate a significant reduction of emissions like HC, CO and PM. With the DEA 5 addition to the DPE 15 blend a reduction in NO up to 20% and smoke opacity of 30% was observed.
