The vast stores of biomass available in the worldwide have the potential to displace significant amounts of fuels that are currently derived from petroleum sources. Fast pyrolysis of biomass is one of possible paths by which we can convert biomass to higher value products. The wood pyrolysis oil (WPO) have been regarded as an alternative fuel for petroleum fuels to be used in diesel engine. However, the use of WPO in a diesel engine requires modifications due to low energy density, high water contents, low acidity, and high viscosity of the WPO. One possible method by which the shortcomings may be circumvented is to cofire WPO with other petroleum fuels. WPO has poor miscibility with light petroleum fuel oils, the most suitable candidates fuels for direct fuel mixing are methanol or ethanol. Early mixing with methanol or ethanol has the added benefit of significantly improving the storage and handling properties of the pyrolysis oil. For separate injection cofiring, conventional diesel fuels can be fired together with WPO-ethanol blended fuels in a dual-injection diesel engine. In this study, performance and emission characteristics of a dual-injection diesel engine were examined. Results showed that although stable engine operation was possible with dual-fuel combustion, the fuel conversion efficiency was slightly decreased due to high water contents of pyrolysis oil. Regarding to exhaust emissions, NOx and soot emissions were significantly decreased.
