Abstract
Increasing air pollution is one of the significant problems globally,
especially in developing countries that are caused mainly by exhaust
emissions from motor vehicles. This study aims to analyse the performance of
a diesel engine using biodiesel as fuel and compare it with pure diesel oil.
In the present study, biodiesel was produced from waste vegetable oil. The
transesterification was performed with methyl alcohol in the presence of
catalyst potassium hydroxide. Blends B10 and B20 were made by mixing pure
diesel and biodiesel fuel. Various parameters such as brake specific fuel
consumption, brake thermal efficiency, mass flow rate, and brake power were
calculated. At 5 kg load, the brake thermal efficiency for B10 was higher
compared to pure diesel and B20 by 13.72% and 10.02 %, respectively, while
the fuel consumption time was 2.35 % and 3.56 % more than pure diesel for
B10 and B20, respectively. At no-load conditions, the fuel consumption rate
for B10 was maximum, 5.17 % and 12.38 % more than that of B20 and pure
diesel, respectively. Thus, without compensating for the power and brake
thermal efficiency, vegetable oil-based biodiesel and its blends can be used
in CI diesel engines as an alternative fuel.
