Abstract

by vehicle emissions. That is why many countries around the world are starting to look for allemative fuels to prevent the higher air pollution. In an effort to find altcrnative fuels to prevent air pollution. The world's major State initially mixed existing fuel with TEL (Tetraethyl Lead) to increase octane numbers, but the resulting mixture caused air pollution that is very harmful to living things that is lead. Therefore, many major world countries such as USA, Brazil and some European countries have replaced them with Ethanol as a fuel mixture. Ethanol use by these countries as a fuel mixture at the time was still at a low level (90% Premium + 10% Ethanol) used for gasoline-fueled motors. In this study using a 4- step motorcycle. Tests conducted here want to know the results of exhaust emissions, fuel consumption, and octane numbers. In the exhaust emissions of the results to be achieved are levels of HC and CO under the established emission standards. In the fuel consumption of the results to be achieved in the form of the lowest fuel consumption of other fuel mixtures, while the octane number of results to be achieved is the highest octane number of fuel tested. In this test using ethanol as a fuel mixture. Ethanol used is ethanol with 96% content. The mixed variations are E0 (100% pertalite + 0% ethanol), Ei0 (90% pertalite + 10% ethanol), Ei5 (85% pertalite + 15 ethanol), E2o (80% pertalite + 20% ethanol). From the test results fuel consumption using speed 20 km / h, 40 km / h, and 60 km / h. At a speed of 20 km / h the lowest fuel consumption occurs in the Eo mixture with fuel consumption of 0.5481 1 / h. At a speed of 40 km / h the lowest fuel consumption occurs in the E0 mixture with fuel consumption of 0.913 1 / H and at a speed of 60 km / h the lowest fuel consumption occurs in the Eio mixture with fuel consumption of 1.304 1 / h. From the fuel consumption test on the Eio fuel mixture of 0.557 1 / h at a speed of 20 km / h, 0.913 1 / h at a speed of 40 km / h, and 1.304 1 / h at a speed of 60 km / h lower than that of fuel E20. From this test it is known that the fuel mixture E2o has the highest fuel consumption compared to other mixtures. Then for exhaust gas emission testing here using engine speed 1500 rpm, 3000 rpm, and 4500 rpm. The lowest CO emission of fuel mixture is found in the E20 mixture which has a CO content of 0.10% at 1500 rpm engine speed, at 3000 rpm engine speed has a CO emission level of 0.11%, and at 4500 rpm engine rotation rate of emission CO of 0.10% lower than CO emission levels that have CO emission levels of 0.21%. The fuel mixture with the lowest emission of MC is E15 which has a HC emission level of 71 ppm at 1500 rpm engine speed, at 3000 rpm engine speed has a HC emission level of 52 ppm, and at 4500 rpm engine speed has a HC emission level of 22 ppm , Lower than the level of HC Eo which has a HC emission level of 100 ppm at 1500 rpm engine speed, at 3000 rpm engine speed has a HC emission level of 81 ppm and at 4500 rpm engine speed has a HC emission level of 69 ppm. Then on octane number testing, the fuel mixture having a high octane octane number is E20 which has an octane number of 106. While for fuels using an ethanol blend the lower octane values are present in the Ejo mixture. Keywords Ethanol.
