ANALISA PENGUJIAN PENGARUH PEMAKAIAN ZAT ADITIF TERHADAP PERFORMANSI MESIN OTTO
Abstract: In this study the
addition of additives for gasoline aims to improve engine performance through the quality
of fuel combustion
with air so
that combustion can
take place completely
and to reduce emissions. This
study also expected to benefit the education and research to know the effect of
additives on engine
performance. Research methods
of testing, data
collection and processing of
test results data.
Test data is
processed include torque,
power, specific fuel consumption, volumetric
efficiency, thermal efficiency
and emissions. The
results showed that the mixture of gasoline additives
(C2:40) has a calorific value of the highest compared with other mixtures, this
is due to
a change in
the composition of
the fuel. Increased
torque at C1:40
and C2:40, but decreased in C3:40. This is because the heating value of
fuel in C3: 40 also decreased. While
the power produced
is influenced by
the torque generated
by the engine.
For the parameters specific fuel
consumption (SFC) in each mixture is lower than usual when using the gasoline
engine. At engine speed 3000 rpm
and load 25 kg obtained
by the use of the lowest fuel.
Volumetric efficiency increases slightly with the addition of the additive
content in the fuel mixture in which the smallest volumetric efficiency occurs
when the engine using gasoline fuel. Thermal
efficiency for a
mixture of fuel
consumption is greater
than using gasoline.
For the parameters emissions, the
use of additives mixed with gasoline to make the percentage levels of CO,
unburned hydro carbon(UHC) and CO2 decreased.
