Pengaruh Variasi Jenis Aktivator Asam dan Nilai Normalitas Pada Aktivasi Zeolit Pelet Perekat Terhadap Prestasi Mesin Motor Diesel 4-Langkah

摘要

The energy crisis and air pollution can be coped with using very abundant Natural Zeolitesavailable in Indonesia, particularly in Lampung. Herry Wardono has applied the zeolite on petroland diesel engines. In this applications, Lampung's natural zeolites can significantly save fuelconsumption and reduce exhaust emissions of the engines. The best results occurred in the use ofchemical-physical activated zeolite. All this time, chemical activator (acidic activator) used wasH2SO4 0.2 N, and other normalities of this acid have not been tested, as well as other types ofacidic activator. In this research, acidic activators used were H2SO4 and HCl which has a normalityof 0.1 N, 0.2 N, 0.3 N and 0.5 N each. The amount of adhesive pelletized zeolite used was alsovariated, i.e 50, 100, and 150 grams. The results showed that the adhesive pelletized zeoliteactivated by HCl dominate the best results, with fuel consumption savings of 8.6472% and10.3058% in the use of 100 and 150 grams of the zeolite. Meanwhile, the highest fuel consumptionsavings obtained in the use of adhesive pelletized zeolite activated by H2SO4 were 6.2992% and7.8847%.
