This research aims to obtain the effect of adding additives on the mixture of 80% methanol (96%) 20% ethanol (10%) that is based on the combustion characteristics as shown by the spaces: specific gravity at 60/60oF, heating value, flash point, kinetic viscosity at 40°C and the specific heat Cp. The method used to determine the effect of adding additives on the mixture of 80% methanol (96%) 20% ethanol (10%) is water boiling test (WBT) start cold and laboratory testing which includes heating value test, specific gravity test, kinetic viscosity test, flash point test. The results showed that the mixture of 80% methanol (96%) 20% ethanol (10%) with the addition of 33.4 ml (500 ml/60 liters of fuel) of additives Top One Power Booster get the temperature of the flame burning at the base is 479°C, the temperature of the flame burning in the middle is 383°C, boiling time (97°C) 1 kg of water is 3 minutes 22 second, fuel consumption is 90 ml, found puddles on kaviti 0.25 ml. It can be concluded that the additives Top One Octane Booster OB-4.5 in the form of caplets/solid containing heavy metals Pb (lead) so it does not dissolve in a mixture of 80% methanol (96%) 20% ethanol (10%), the addition of 33.4 ml of additive Top One Power Booster in a mixture of 80% methanol (95%) 20% ethanol (10%) to increase the heating value, the kinetic viscosity, specific heat and degrade the specific gravity, density and flash point. |
