ABSTRACT
This study investigated the potentials of waste
cooking oil as an alternative feedstock for diesel engines. It involved the
fuel production and its analysis phase as well as the engine performance and
its analysis phase. In the first phase, biodiesel was produced from waste
cooking oil. The waste cooking oil was collected from big restaurants and
transesterified by heating the oil with large excess anhydrous methanol using
potassium hydroxide (KOH) as a catalyst to speed up the reaction. The fuel
properties such as kinematic viscosity, oxidation stability, cetane number,
density and specific gravity, flash and boiling points, cloud and pour points,
acid and methanol values, water content and heat of combustion (lower calorific
value) were determined and compared with those of fossil diesel and the ASTM
recommended values for biodiesel. From the analysis, the calorific value of
biodiesel was 40.01MJ/kg
as compared to that of fossil diesel, which was 45.345MJ/kg
while the viscosity, flash point and cetane number were 4.1mm/s2,
130℃,
and 52 respectively as compared to be higher than that of the fossil fuel,
which were 3.41mm/s2, 65℃ and 46 respectively.
In the second phase, a diesel engine was fuelled with the biodiesel and fossil
diesel one after the order and the engine performance criteria such as
indicated power, brake power, brake thermal efficiency, mechanical and
volumetric efficiencies as well as specific fuel consumption were analyzed and
compared. In addition, exhaust gas analysis was carried out to determine the
pollution problems associated with the production and consumption of waste
cooking oil biodiesel. The work reveals that biodiesel exhibits similar
performance on diesel engine when compared to fossil diesel and possesses
better emission characteristics and should therefore baring the problems of
availability be preferred to fossil diesel for powering diesel engines.
