Investigations of Collateral Effects of Fuel Additives on Diesel Engine Smoke Emissions

Abstract

Five multifunctional fuel additives were tested in a truck diesel engine in order to evaluate their smoke reduction effect. The research multifunctional additive packages A1-A5 were based on functions of dispersant-detergent, antiknock, friction modifier, thermal stabilizer, and corrosion inhibitor, being mixed in the recommended concentration of the supplier. The engine was operated under test cycles ECE R 24 and ECE R 49. Results indicated that three out of five additives proved to contribute to the lowering of the smoke emissions.
