Abstract

The paper presents the experimental study results of rapeseed methyl esters (RME), mineral diesel fuel (MD) and their blends, containing 10, 30 and 50% volume RME to MD additives droplet ignition under critical conditions in heated oxidizing atmosphere (in air). The efficient activation energy values are calculated for studied fuels in 900-970K temperature interval. Efficient activation energy values were (30,7 ± 0,5) kcal/mole in 905-927 К temperature interval and (49,9 ± 0,5) kcal/mole in 949-969 К temperature interval for RME and MD respectively. It was shown, that the efficient activation energy value decreases while adding RME to MD, and that the additive law can be submitted in efficient activation energy value calculations for blended fuels.
