An Analysis of Biodiesel Combustion on Diesel Technologies

The 2 set of engine experiments have been conducted to verify the effect of biodiesel blended fuel on diesel combustion for the low pressure diesel direct injection and common-rail direct injection. For low pressure (300 – 500 bar.G), the presence of biodiesel affect to the improvement of fuel ignition quality. While, the common-rail DI, the fuel conversion efficiency and ignition quality could help improving the engine combustion only at low speed high load condition. This result, at least, broaden our understanding that only 6 number higher in cetane quality will not discriminate the engine performance especially at steady-state condition.
