Increase in the demand for the alternative fuel for
diesel engine as led to quest for feasible fuel with competitive cost
and environmental friendly compared to petrolium fuel. This
article deals on waste energy recovery. The aim of this
experimental work is to find an attractive alternative fuel for the
diesel engine by harnessing fuel from waste disposed oils. Waste
Cooking Oil (WCO) and Waste Lubrication Oil (WLO) energy
sources are used for fuel production. Collected WCO stored in a
container, mixed and cleansed by removing solidified fats and
other food leftovers before the transesterification. The acid
followed by base catalyst transesterification processes carried out
for biodiesel production. The WLO oil cannot be used directly in
diesel engine and hence it is processed to be used like DLF using
pyrolitic vacuum distillation method. The characteristics test such
as flash point, fire point, density; viscosity and calorific value of
the produced biodiesel, DLF, B10, B20, B30 and B40 were
determined & compared with standards. Performance and
Emission characteristics conducted in a single cylinder, free
aspirated, water- cooled computerized diesel engine setup and
results discussed. Results outcome shows that B30 exhibits the
similar performance as pure diesel. The results show an
improvement in brake specific fuel consumption, thermal
efficiency. The unburned hydrocarbons, carbon monoxide
emissions less but increase in the NOx.
