Abstract

Indonesia is one of the countries with the third highest level of air pollution in the world. The contribution of motor vehicle exhaust emissions as the largest source of air pollution reaches 60-70%, compared to industry which only ranges between 10-15%. The purpose of this research is to find out the Comparison of Flue Gas Emissions Using Pertalite Fuel with LPG Fuels on the Tr200 Triarrows Engine , The testing place at the Mechanical Engineering Lab of the University of Muhammadiyah Pekajangan Pekalongan, the research method using descriptive data analysis methods and as a dependent variable CO and HC flue gas and independent variables are 2500 rpm, 3000 rpm, 3500, 4000 rpm, 4500 rpm and 5000 rpm. Tests were conducted to determine the value of exhaust emissions on pertalite fuel and LPG gas fuel on the Triarrows Tr200 Generator. From the results of the study it was found that some significant decreases in the value of CO gas emission occurred at 3500 rpm - 5000 rpm which is the concentration decreased by 7.97% from 8.07% to 0.1% at 3500 rpm. While the concentration of HC gas emissions which is very significant at 2500 rpm - 5000 rpm which is the value of concentration decreased by 3945 ppm from 4412 ppm to 467 ppm at 3000 rpm.

Abstract

Essential oils are volatile compounds at room temperature derived from aromatic plants (such as vetiver, cloves, lemongrass, nutmeg, cananga, cinnamon) because the content of these essential oils has many benefits, including improving engine performance, cleaning fuel injectors, reduce the deposition of organic compounds in the combustion chamber, and can save fuel consumption and reduce exhaust emissions. The purpose of this study was to determine how much influence the addition of essential oil to pertalite fuel to reduce the concentration of CO and HC and increase CO2 levels in motorized vehicles. This test was carried out by adding the percentage of essential oil mixing as much as 6 ml, 12 ml, and 18 ml on pertalite fuel with engine speed variations of 1000, 1500, 2000, 2500, and 3000 rpm. Based on the test results, it was found that several significant decreases in the emission concentration value of CO levels occurred at the engine speed of 2000 rpm - 3000 rpm. The percentage of essential oil 12 ml is down by 0.30% from 1.02% to 0.72% at 3000 rpm engine speed. While the concentration of emission levels of HC from engine speed of 1500 rpm - 3000 rpm has decreased significantly, at 3000 rpm engine speed for 12 ml of essential oil percentage decreased by 30 ppm from 185 ppm to 155 ppm.

Abstract

Motorcycles are equipped with a power transfer system that is able to bridge the engine output (engine power and torque) with the demands of road conditions, the sprocket is the last part of the power transfer system, because the sprocket is the part that transmits the engine power to the rear wheels through the chain. Previous researchers changed the size of the sprocket with a sprocket eye larger or 2 points smaller than the standard sprocket, while in this study replaced the rear sprocket with a large number of eyes and 4 points smaller than the standard sprocket. The purpose of this study was to determine the effect of variations in rear sprocket size on power and torque on the 2015 Vixion motor. This study used the data collection method from the daynote test using a dynamometer. The test results are the effect of variations in sprocket sizes 43T, 39T, and 47T resulting in an increase in power and the most optimal torque on the sprocket size 47T with a maximum power data of 16.1 HP, and torque data obtained with sprocket size 47T produces a maximum torque of 14.42 Nm. due to the large number of sprockets and the shorter distance between the front and rear sprockets.

Abstract

In reducing the remaining harmful exhaust emissions of motorcycles, one of them is by improving the quality of fuel and vehicle technology so that the combustion becomes better and more optimal, then the second way is to process exhaust gas through an exhaust emission controller. Catalytic Converter is a device that is installed in the exhaust channel of vehicle which has function to reduce the residual emissions from motorized combustion gases. The purpose of this study was to determine the effect of using a catalytic converter made of brass with a thickness of 0.2 mm to reduce levels of CO and HC in motorized vehicles. Tests were carried out by using a gas analyzer to determine the value of CO and HC concentrations. The exhaust emission test is carried out in two stages, the exhaust emission test with a standard exhaust and exhaust gas emission test with a catalytic converter with the variations of engine speed of 1500 rpm, 2000 rpm, 2500 rpm, 3000 rpm, 3500 rpm, 4000 rpm. From the research results, it was found that the effect of using a catalytic converter made of brass with a thickness of 0.2 mm with a fin model the most effective decreased on exhaust emission levels was at 1500 rpm, the CO value decreased by 1.82% from 3.96% to 2.14%. and HC value fell 4,412 ppm from 9,999 ppm down to 5,587 ppm.
