Three advanced biofuels iso-butanol, n-pentanol and DMC were used as blends with diesel.
Combustion-phasing and charge-dilution was controlled by EGR and injection timing modification.
All blends presented enhanced premixed combustion with high peak pressures and peak HRR.
Simultaneous reduction of NOx/smoke was realized with all blends at moderate EGR & late injection.
HC and CO emissions increased.
