Pengaruh Variasi Temperatur dan Derajat Keasaman (pH) Air Pencucian Pada Aktivasi Zeolit Pelet Terhadap Prestasi Mesin Diesel 4-Langkah
Abstract: One of efforts to
save fuel consumption can be done by using thermal-acid activated zeolite as
adsorbent for water vapor and nitrogen. Herry Wardono has proved that the value
of concentration of 0.3 N and 0.5 N in the chemical activation can save
specific fuel consumption. The best result occurred in the use of
thermal-chemical activated zeolite. In this research, thermal activation
temperatures used were 150 0C and 200 0C respectively for 1 hour. Variations of
washing water pH were also performed on the 4.5, 5.5 and 7. The results showed
this thermal activation of 200 0C on activator HSO24 0.3 N and HCl 0.3 N can
save fuel by 5.350% and 7.811% respectively. Then the pH value of 7 gave the
best fuel consumption savings those were of 5.964 % and 7.175% for use of HSO
0.5N24 and HCl 0.5N. This result occured at low speed (1500 rpm).
