Abstract:
The twin problems of environmental pollution and energy shortage need to be
carefully planned for gradual shift from fossil fuels to renewable sources of
energy. It has become highly prominent in the present situation to look for
substitute fuels that has potential of justifiable development, energy protection,
efficiency and ecological protection. The bio-origin fuels can provide a viable
solution to this worldwide petroleum crisis and environmental safety.
The existing engines are normally designed and manufactured in accordance to
diesel as fuel. The suitability of fuel obtained from alternative source is yet to
be studied whether the new fuel gives desired performance and emission
characteristics. In this work, low speed Direct Injection (DI) diesel engine has
been modified to run on alternative fuel in dual fuel mode. This engine was
tested with diesel/polanga biodiesel as primary fuel and ethanol as secondary
fuel.
