Abstract

Research in utilization of Lampung natural zeolite/coal-fly ash was performed to observe its effect on fuel consumption savings and the reduction of exhaust emissions on a 4-stroke petrol motorcycle. Percentage variations of zeolite/coal-fly ash were abbreviated by 0/100 (Z0-F100), 25/75 (Z25-F75), 50/50 (Z50-F50), 75/25 (Z75-F25), and 100/0 (Z100-F0) (wt.%). Tests of fuel consumption were conducted by stationary tests at engine speed of 1000, 3000, and 5000 rpm and road tests as far as 5 kms. Meanwhile, exhaust emissions tests were performed at engine speed of 1500 and 3500 rpm. Filter of zeolite/coal-fly ash was put on the air filter casing, so before entering the combustion chamber, the combustion air was firstly contacted with this filter. The test results showed that the best fuel consumption savings for stationary tests occurred in the use of filter Z25-F75 that is as big as 53.06%, and the best fuel consumption savings in road tests as long as 5 km at a constant speed of 60 kph also occurred in the use of filter of Z25-F75 that is by 33.43%. In addition, the highest reduction of CO and HC concentration also occurred in the use of filter of Z25-F75 that is by 38.47% and 30%, respectively.
