Abstract: The paper presents the test results of a Dl diescl engine D-243 operating alternately with aviation-lurbine JP-8 fuel treated with 0.04.(J04), 0.08 (.108), 0.12 (.112), 0.16 (J 16), and 0.24 (.124) vol% with the eetane improving additive and 5 (J5), 10 (JI0), 20 (.120), and 30 (.130) vol"? rapeseed biodiesel (RME). The effects of 2-ethylhexyl nitrate and biodiesel on autoignition delay, heat release rate, iii-eylinder pressure, engine performance efficiency, exhaust emissions and smoke provided for sound interpretation of the lest results for 15%, 50%%, and 100% loads at the maximum torque speed of 1400 rpm and 10%, 50%, and 100% loads at rated speed of 2200 rpm. Reduction in ignition delay was achieved at all loads and speeds when using eetane additive- and RME-treated .IP-8 fuel, but the shorter ignition delay did not always result to better performance efficiency of an engine. The fuel blend J12 developed brake thermal efficiency 1.4% higher at low 1400 rpm, whereas biodiesel-lreated JP-8 suggested 1.0% (.15) to 3.6% (.130) better performance of a fully (100%) loaded engine at 2200 rpm. The higher CN rating of JP-8 fuel did not reduce the HC, CO emissions and smoke (soot) as could be expected due to the limited a real time of each engine cycle to burn the fuel completely, especially at a high speed
