Performance of a single cylinder diesel engine fuelled with emulsified residual oleins and standard diesel fuel

Abstract

Emulsified residual oleins and standard diesel fuel were evaluated. The engine tests for the fuels analyzed were performed in a Petter single cylinder direct injection diesel engine under steady state conditions at fixed torque values (20 Nm and 34 Nm) and the engine speeds (n) between 1300-1700 rpm. Power output, specific fuel consumption, ignition delay and exhaust composition were evaluated. The emulsified residual oleins (ERO) shown lower power output joint to a higher specific fuel consumption related to the lower heating value of residual oleins compared to diesel fuel. A shorter ignition delay was observed for the ERO. Decreases in NOx emission were obtained for ERO compared to diesel fuel. The use of ERO in order to be a partial or full alternative to the use of diesel fuel for energy production was achieved.

Emulsification of animal fats and vegetable oils for their use as a diesel engine fuel: An overview

“…the ignition delay. Similarly, changes in the ignition delay for emulsified biofuels have been reported [37,43,46,49,88,89]. According to Armas et al [39] and Badran et al [71], it is a consequence of the heat absorption by water vaporization in the fuel jet.…”
