Abstract
One of the alternative fuel that can be used for Otto engines is bioethanol. Bioethanol has a high octane number and higher oxygen content than gasoline and produced emissions are more environmentally friendly. This research to determine the Otto engine stationary four-stroke performance when using a gasoline-bioethanol mixture. The study was carried out with variations in the composition of the mix of bioethanol-gasoline, variations in engine speed and load engine. The experiment results show that the maximum thermal efficiency obtained is 29.63% when using gasoline at 1000 rpm and the load of 20 kg. The minimum SFC value is obtained 284.47 gr/kWh at 1000 rpm when using gasoline for the load of 20 kg. The SFC has increased when using a bioethanol-gasoline mixture. However, the exhaust emissions produced when the engine uses a mix of bioethanol-gasoline, it becomes more environmentally friendly.
