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

The perfect combustion process can occur if the high compression pressure, proper ignition time, and suitable fuel air mixture. Suitable fuel air mixture can be obtained by heating the fuel to reduce its viscosity so the mixture is more homogeneous. Fuel heating can be done in various ways, such as by utilizing the heat of radiator water coming out of the engine. The purpose of the study is determine effect of the fuel heating to exhaust emission of gasoline engine 1800cc. The study uses experimental with the variable used pertamax with temperature 40°, 50°, 60°, and 70°. The dependent variable in the study is exhaust emission of gasoline engine. The results of the study indicate that fuel heating affects exhaust emissions. Temperature that affects the exhaust gas emissions at 60o C with the use of pertamax fuel.

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.
