Abstract

The increase in the number of motorized vehicles increases every year so that air pollution also increases. Lack of public awareness about reforestation makes the air difficult to circulate. The number of motorized vehicles is also a major factor in increasing air pollution. Exhaust emissions from motorized vehicles are harmful pollutants to the human body. Exhaust gas from motor vehicles contains toxic compounds, one of which is carbon monoxide (CO) and hydro carbon (HC) which are very dangerous for the environment and humans. The purpose of the study is to make a tool that can control exhaust emissions. Sponge steel-based muffler uses sponge steel as a means of continued combustion of the exhaust gas, sponge steel heating is produced from the heat of the exhaust gas itself. The heat from the sponge steel coupled with the pressure from the exhaust gas itself will increase the heat from the sponge steel, so the sponge steel can burn. With the heat from the sponge steel the gas that has not been burned in the combustion chamber will be burned again in the exhaust by a sponge steel, so that CO and HC gas will be burned with O2, CO2, O2 and H2O gases will be obtained. The method of the study is experimental methods. An experimental research study conducted by manipulation that aims to determine the results of manipulation of individual behavior observed. The data observed in this study included a exhaust gas emissions, power, and specific fuel consumtion (SFC). The result of the study, Sponge steel based exhaust can reduce exhaust emissions, in HC compounds can decrease by 24.79% and CO decreases to 29.70%, reduced power by 5.64% is not too significant from standard exhaust, and SFC decreased by 3,12%.

Abstract

One way to improve the performance of gasoline engines is by using bioethanol, which can enhance combustion efficiency. Bioethanol, a renewable fuel derived from the fermentation of plant materials, can be blended with traditional fossil fuels to create a more efficient and environmentally friendly fuel alternative. The combination of fossil fuel and fermentation-derived fuel has a significant impact on the overall performance and emissions of the engine. The aim of this study is to determine the magnitude of changes in torque and power when a gasoline engine is fueled with a mixture of corn cob bioethanol and pertamax. Additionally, specific fuel consumption will be determined to evaluate the fuel efficiency. The engine used in this study is a 150cc gasoline motor, a common size for motorcycles and small vehicles. The testing variables include engine speed variations from 2000 to 9500 rpm using bioethanol blends of 5%, 10%, and 15% with 92 octane fuel. The data collected from these tests is calculated mathematically. The results of the study show the largest increase in power at 0.45 horsepower at 2500 rpm and torque at 2.82 Nm at 2500 rpm when using the BE15% fuel blend, indicating a notable enhancement in engine performance with higher bioethanol content. Furthermore, the smallest decrease in fuel consumption was recorded at 0.1739 kg per horsepower, highlighting the efficiency benefits of bioethanol blends. Overall, the engine performance improves when using a blend of 92 octane fuel with bioethanol compared to pure 92 octane fuel. This suggests that incorporating bioethanol into gasoline can not only improve power and torque but also enhance fuel efficiency, making it a viable option for reducing dependency on fossil fuels and lowering emissions.

Abstract

This study aims to analyze the effect of barriers on standard intake manifolds on exhaust emissions in 125cc capacity injection motors. The applied barrier is expected to modify the intake air flow, which has an impact on the combustion process and the resulting exhaust emissions. The method used includes testing exhaust emissions with variations in the use of barriers under several engine conditions, including different engine speeds. The results show that the use of barriers can affect CO, HC, and O2 emission levels, with certain variations indicating changes in combustion efficiency. The conclusion of this research is that the selection of the right barrier diameter and intake manifold shape can contribute to the reduction of exhaust emissions of 125 cc injection motorcycles. The results of this study are expected to be a reference for the automotive industry in designing a more environmentally friendly intake manifold system.

Abstract

The development of technology in the 4.0 era has led to higher energy consumption. Meanwhile, Indonesia's energy consumption has been increasing every year. This requires the substitution of alternative energy vehicle fuels. One of them is bioethanol. Bioethanol can be obtained from plants, namely molasses. The use of RON enhancers can increase the octane rating so that low quality fuel can be used. By using high octane, the performance and fuel consumption will be optimal. The purpose of this study was to determine the performance of a 4-stroke petrol engine. This research uses an experimental approach where direct experiments are carried out on torque, power and fuel consumption. The data obtained is also presented graphically. In this study, the independent variables used were Ron enhancers with masses of 0ml, 5ml, 10ml, 15ml and molasses bioethanol percentages of 0%, 10%, 15%, 20%. Control variables engine speed 5500 rpm to 9000 rpm. The highest power results were obtained with a mixture of 0% bioethanol and 5ml RON enhancer, 7.90hp at 8000 rpm. The highest torque is achieved with a mixture of 0% bioethanol and 15ml RON enhancer 8.74 Nm at 6000 rpm. For fuel consumption, the 15% bioethanol mixture with the addition of 0ml RON enhancer is the lowest at 0.0804 kg/Hp.hour at 6000 rpm.

Abstract

Vehicle ignition systems, including spark plugs, are a certain way to boost a motorcycle's performance. One kind of spark plug used to ignite the combustion process in a gasoline engine is a multi electrode spark plug, which has two or more ground points built into the electrodes. This study's overarching goal is to identify the optimal combination of multi-ground spark plugs, gasoline octane value fluctuations, and power/torque/specific fuel consumption parameters. Engine performance testing relies on data collected from controlled laboratory tests. In addition, Microsoft Excel is used for data analysis, and the results are shown in graph tables. Spark plug electrode amount in feet and gasolines octane level are the independent variables. Speed the engine from 5500 to 9000. The peak power output of 6.92 Hp was achieved at 7000 rpm in the power test with RON 92 gasoline X-Line spark plugs. At 5500 rpm, the maximum torque of 8.21 Nm was produced by the torque test using RON 98 gasoline X-Line spark plugs. At 6000 rpm, the specific fuel consumption test with RON 90 fuel and standard spark plugs yields a value of 0.0800 kg/Hp.hour.

Abstract

The rocker arm functioned as a link between the camshaft and the valve which was responsible for regulating the rise and fall of the valve. Based on how it worked, the roller rocker arm with a conventional rocker arm were the same. However, a significant difference was seen in the roller placed at one end that made direct contact with the camshaft. The use of a conventional rocker arm produced considerable friction, so researchers replaced it with a roller rocker arm. The purpose of this study was to improve the performance of a single cylinder petrol engine using a roller rocker arm that had diameter sizes of 15 mm and 17 mm against the standard. The performance testing method used the variable open throttle to obtain data. Furthermore, the data was presented in graphical form and analyzed using anova. The independent variables were roller rocker arm whose diameter were 15 mm and 17 mm, conventional rocker arm and round 3000, 3500, 4000, 4500, 5000, 5500, 6000, 6500, 7000 rpm. The dependent variables were power, torque and specific fuel consumption. The control variables were engine 100 cc and 92 octane fuel. The largest power result at 6500 rpm was 6.25 Hp using a conventional rocker arm. The largest torque at 3500 rpm was 7.23 Nm using a 15 mm roller rocker arm. The smallest specific fuel consumption was 0.1546 kg/Hpxh at 5000 rpm using a 15 mm roller rocker arm.
