One of the methods that allows reduce the specific fuel consumption of Diesel engines and avoid possihle damage ofthe environment by harmful exhaust gases is application ofthe fuel additives. The purpose of this research is to determine the influence of the fuel additive SO-2E on the fuel consumption of a direct-injection Diesel engine and to evaluate the quantitative emission composition changes and smoke opacity of the exhausts. Investigations were conducted on the four cylinder, four stroke, naturally aspirated, water cooled. 59 kW Diesel engine D-243. Test results show that the application of fuel additive SO-2E in proportion 1:500 (by volume) does not have significant Influence on the brake specific fuel consumption. The total emission of nitrogen oxides Nox at the rated performance regime due to the usage of the fuel additive reduces by 11.6 percent, primary because of lower NO concentration. The carbon monoxide CO emission from fully loaded engine at the rated speed due to application of the fuel additive SO-2E increases up to 20 percent, although at other performance regimes the additive influence is minor. The smoke opacity from treated fuel at light-to-moderate loads slightly decreases, however at the engine rated speed it becomes by 5 - 10 percent higher.
