Abstract

Liquefied Petroleum Gas (LPG) is a derivatives of crude oil that contains several methane, butane, and the other hydrocarbon’s product. Liquefied Petroleum Gas can be utilized as a vehicle fuel because of its inexpensiveness. The use of LPG as a vehicle fuel can be optimized with adding turbulator in the intake manifold. With the addition of a turbulator, the exhaust emission can be reduced and the fuel consumption of a LPG-fueled motorcycle become more efficient. The objectives of this research are: (1) Investigate the angle of inclination of turbulator blades which generates lowest exhaust gas emissions’ of CO and HC on the LPG-fueled 4-strokes motorcycle. Investigate the angle of inclination of turbulator blades which generates the most efficient fuel consumption on the LPG-fueled 4-strokes motorcycle. This research used the 2006 Honda Supra 125 D as the sample. Variable used in this research is the addition of turbulator in the intake manifold with the variation of 30°, 45°, and 60° blades inclination angle. The result showed that the addition of a 30° turbulator can reduce the fuel consumption of LPG fuel with the result of 14,75 g/km. Meanwhile, using pertalite can consume 20 g/km. This also showed that the addition of a turbulator is more efficient than using refined fuel oil. The addition of a 45° turbulator resulting the most environmentally friendly with the exhaust emission result of 0,14% CO and 995,67 ppm HC.
