Abstract: The article focuses on bench testing results of a four-stroke, four-cylinder, direct-injection, naturally aspirated, diesel engine i ting on the normal 95vol% (class C) diesel fuel + 5vol% RME (DF), F-34jet fuel (JF) andjet fuel F-34 treated with the : improver (JF+0.12vol%). The purpose of the research is to investigate the availability to use of military F-34 jet fuel bland-based direct injection diesel engine powering and examine the effect ofF-34fuel and F-34fuel treated with 0.12vol% tylhexyl nitrate on the autoignition delay, combustion, engine performance, emissions and smoke opacity of the exhausts. The peak in-cylinder gas pressure generated from JF and JF+0.12vol% is lower by 4.3% and 2.8% at 1400 min' , and 2.5% and 5.7% at 2200 min'' speed compared to that 86.6 MP a and 82.5 MP a of the normal diesel. At rated i min~' speed, the use of treated jet fuel leads to smoother engine performance under all loads and the maximum der pressure gradient lowers by 9.4% as against that 15.9 bar/deg of base diesel. The minimum brake specific fuel mption (bsfc) for F-34 and treated F-34 fuels decreases by 4.8% and 3.5% at 1400 min'1 speed, and increases by and 3.7% at. 2200 min'1 speed compared to 249.5 g/kWh and 251.8 g/kWh values of base diesel. Maximum NO emissions produced from fuels JF and JF+0.12vol% decrease by 11.5% and 7.0% at 1400 min', and J% and 17.3% at 2200 min'1 speed compared to 1705 ppm and 1389 ppm emanating from the normal diesel. ' rtum CO emissions produced from jet fuel JF and JF+0.12vol% decrease by 39.3% and 16.8% compared to that W0!f8ppm producedfrom base diesel running at 1400 min'1 speed, At 2200 min' speed, the ecological effect of using fuel "M fuel decreases and the CO sustains over the whole load range at the same level and increases by 2.5% and 3.0% I regard to the normal diesel operating under high load...
