Abstract
Direct injection compression ignition engines have proved to be the best option in heavy duty
applications like transportation and power generation, but rapid depleting sources of conventional fossil
fuels, their rising prices and ever increasing environmental issues are the major concerns. Alternate fuels,
particularly biofuels are receiving increasing attention during the last few years. Biodiesel has already
been commercialized in the transport sector. In the present work, a turbocharged, intercooled, DI diesel
engine has been alternatively fuelled with biodiesel and its 20% blend with commercial diesel. The
experimental results show that BSFC, maximum combustion pressure and start of injection angle
increase; on the other hand BSEC, maximum rate of pressure rise, ignition lag and premixed combustion
amount decrease; however HRR duration remains almost unaffected in the case of biodiesel as compared
to commercial diesel.
