AB  - In order to investigate the burning characteristics of a 0# diesel and 3# jet fuel, a small-scale experimental bench mainly composed of a cone calorimeter was arranged. The heat release and burning rates were investigated changing the external irradiance in order to clarify the triadic relationship among these quantities. The effective heat of combustion of 0#  diesel  and  3#  jet  fuel  were  38.89  MJ/kg  and  43.15  MJ/kg,  respectively,  with  the  corresponding combustion efficiencies being 96.78% and 99.60% (the effective peak heat of combustion  being  1.665  times  the  mean  value  for  both  types  of  fuel).  According  to  our  experimental results, the heat release rate and burning rate of 0# diesel and 3# jet fuel both grow linearly with an increase in the external irradiance. Moreover, the heat release rate and burning rate of 3# jet fuel are greater than the equivalent values for the 0# diesel. The average smoke production rate of 0# diesel grows with an increase in the external irradiance, while for the 3# jet fuel it remains approximately the same. The specific extinction area of these two kinds of fuel shows a subtle decrease with the increase of external irradiance. The time to ignition of 3# jet fuel is smaller than 0# diesel for all the considered external irradiances, which indicates that 3# jet fuel is easier to ignite than the 0# diesel
