Biomass derived fuels are preferred as alternative fuels for IC engine due to its abundant availability and renewable nature. In the present work, the complete replacement of diesel fuel with bio-fuels is studied, where the bio-fuels, namely, methyl ester of palm kernel oil and eucalyptus oil were chosen and used as fuel in the form of blends. Various proportions of palm kernel oil and eucalyptus oil are prepared on a volume basis and used as fuels in a single cylinder, fourstroke DI diesel engine, to study the performance and emission characteristics of these fuels. In the present investigation a methyl ester derived from palm kernel oil is considered as an ignition improver. The results show a 50% reduction in smoke, 34% reduction in HC emissions and a 37.5% reduction in CO emissions for the MePKo50-Eu50 blend with a 2.7% increase in NOx emission at full load. There was a 2.6% increase in brake thermal efficiency for the MePKo50-Eu50 blend at full load. The characteristics of Me PKo-Eu blends are comparable with those of standard diesel.
