Abstract

Fuel is one of the main needs of motorized vehicles. Most motorbike riders want the fuel they use to produce greater torque and power than standard specifications with lower exhaust emissions but save fuel. For this reason, several alternative solutions are needed to overcome this problem, including the use of additives, one of which is eco racing. The aim of this research is to determine the effect of adding eco racing to fuel variations on torque, power and exhaust emissions of 125 CC motorbikes. The research approach was carried out quantitatively by conducting descriptive analytical experiments. Data collection was carried out with various fuel variations at several engine rotation speeds. The research results showed that the mixture of Pertalite with 1 Eco Racing tablet and Pertalite with 2 Eco Racing tablets did not have much effect on power and torque, but increased exhaust emissions. Then, a mixture of Pertamax with 1 Eco Racing tablet and 2 Eco Racing tablets also does not really increase power and torque, but does increase exhaust emissions. The expected result of this research is to determine the effect of adding eco racing on engine performance. From the test results it was found that the addition of eco racing did not increase power and torque, but instead increased exhaust emissions.

Abstract

Biomass is a type of solid waste that is used as an alternative energy source to replace fossil fuels (petroleum) because it can be renewed. Biopellets are a renewable fuel that comes from biomass. The aim of this research is to determine the characteristics of coconut waste biopellets. young with the addition of zeolite variations. The research method used is experimental research. The zeolite material used has 6 dosage variations, namely 0% (0 gram), 5% (2.5 grams), 10% (5 grams), 15% (7.5 grams) , 20% (10 grams), 25% (12.5 grams), with fixed variations from 50 grams of young coconut waste, tapioca flour adhesive and 20 grams of sugar cane molasses. The best burning rate of young coconut waste biopellets was obtained with the T 5 biopellet composition with a molasses adhesive composition with the addition of 5% zeolite with a value of 0.017% g/s. and the lowest water content value is found with the T 25 biopellet composition using molasses adhesive with a 25% zeolite mixture. And the best ash content value can be with P 0 biopellet composition using tapioca flour adhesive without zeolite mixture with a value of 3.32%.
