PENGARUH VARIASI NORMALITAS NaOH PADA AKTIVASI BASAFISIK ZEOLIT PELET PEREKAT TERHADAP PRESTASI SEPEDA MOTOR BENSIN 4-LANGKAH
Abstract: Natural zeolite is
an alternative adsorbent. It needs firstly to
be activated before using it as absorbent in order to get zeolite with
high adsorption capacity. Previously, the use of pelletized zeolite activated by
NaOH-physic and KOH-physic with varied normalities was only performed in a
diesel engine to observe the engine performance.
In this study there were two kinds of activation, that is chemical activation with NaOH activator
variation on the normality of 0.25 N, 0.5 N, 0.75 N, and 1.0 N and physical
activation with using a temperature of
220 °C for 2 hours. All are made in the form of adhesive zeolite pellets with a
diameter of 10 mm and a thickness of 3 mm.
From the test results and analysis showed that the use of chemically
activated zeolite can improve the performance of 4-stroke petrol engine when
compared without using zeolite. The best
performance in this experiment obtained at the normality of 0,75 N. At road
test, the pelletized zeolite can reduce the fuel consumption 23, 15 %, and 16,51
% at stationary test, and increase acceleration by 14,77 %.
