Abstract
Physical, chemical, and fuel properties of diesel fuel samples were investigated in the research. Combustion heats as higher heating values (HHV) of the samples were determined experimentally and calculated from ultimate analysis data. The HHV (MJ kg
−1
) of the samples as a function of carbon (C, wt%) and hydrogen (H, wt%) was calculated from the following equation :
for which the correlation coefficient was 0.999. The calorific values calculated from the equation showed a mean difference of 0.41 %.
