dc.description.abstractThe article presents the bench testing results of a four stroke, four cylinder, unmodified, naturally aspirated DI diesel engine running on diesel fuel (DF) and Jet A-1 fuel (JF) treated with various percentage 0.04 %, 0.08 %, 0.12 %, 0.16 % and 0.24 vol % of cetane number (CN) improver. The purpose of the research is to conduct analysis of the autoignition delay, performance, combustion, and emissions of diesel engine running on diesel fuel as a starting point version and fuel Jet A-1 to recommend this alternative kerosene based fuel for using in battlefield military equipment. Replacing diesel fuel with Jet A-1 increases the autoignition delay and reduces both the maximum cylinder pressure by 6.5 % and maximum pressure gradient by 9.3 % at maximum torque. The maximum cylinder pressure is 4.4 % lower, however the maximum pressure gradient increases by 2.2 % when running at rated power. The additive 2-ethylhexyl nitrate does not actually affect the maximum cylinder pressure, however, it reduces the maximum pressure growth in the cylinder. The brake specific fuel consumption (BSFC) of the fully loaded engine decreases by 1.8 % at 1400 rpm speed and increases by 2.5 % at 2200 rpm speed compared to normal diesel. The effect of CN improver (0.12 %) on the BSFC is small at maximum torque, but the BSFC of the fully loaded engine increases by 2.3 % and 1.2 %, respectively, at 1800 rpm and 2200 rpm speeds. The maximum NO emissions reduce by 11.5 %, 11.8 % and 17.1 % when running the engine on fuel Jet A-1 at 1400, 1800 and 2200 rpm speeds. The influence of 2-ethylhexyl nitrate on the NO emission is ambivalent enough, – because of adding cetane improver 0.12 % by mass the NO emission increases by 5.0 % at 1400 rpm speed and reduces by 1.1 % and 0.8 % at higher 1800 and 2200 rpm speeds. When running of the fully loaded engine on fuel Jet A-1, the maximum CO emission reduces 2.8 times, by 15.0 % and increases by 15.7 % aten
