Abstract

Abstract. This study aims to see the ability of Biodiesel fuel to Engine Performance on
Dong Feng diesel engines with 7 kW Power. The biodiesel used was synthesized by
Biodiesel using frying oil and methanol as well as limestone catalyst (CaCO3). There
are 2 types of Biodiesel used, namely Biodiesel with synthetic catalysts (homogeneous)
and Biodiesel with natural (heterogeneous) catalysts. The synthesis catalyst resulted in
a 31.52% randement, while the natural catalyst produced a 78.79% randement.The
produced biodiesel was tested on a Dong Feng diesel engine with 7 HP Power. To get
a comparison of engine performance, Biodiesel fuel is used with synthetic catalysts
(homogeneous), Biodiesel with natural (heterogeneous) catalysts, and Solar fuels. The
results showed that the engine power produced from Biodiesel was lower than the
engine power using Solar. Power from Biodiesel with synthetic catalysts
(homogeneous) averages 33% lower than Power using Solar, while Biodiesel with
natural catalysts (heterogeneous) is 41% lower than Solar-powered Power. Fuel
Consumption, FC (g/ hour) on the engine using Solar is higher than FC engine using
Biodiesel. FC from Biodiesel with synthetic (homogeneous) catalyst is an average of
7% lower than Solar, while Biodiesel with natural catalyst (heterogeneous) is 30%
lower than Solar. This proves the use of Biodiesel fuel with heterogeneous catalysts is
more economical than Solar fuels.Specific Fuel Consumption (SFC), also shows that
SFC on a Solar fueled engine is almost equal to the SFC Biodiesel fueled engine. SFC
from Biodiesel with synthesis catalyst (homogeneous) is 4% lower than Solar fuel,
while Biodiesel with natural catalyst (heterogeneous) is 7% lower than Solar fuel.
