Abstract

A vehicle engine's performance can be determined through exhaust emission tests. Exhaust emissions contain air pollutants that result from incomplete fuel combustion in the vehicle's combustion chamber. This is usually due to improper oxygen and air mixture conditions. Gasoline (CxHy) burns and reacts with oxygen (O2) to produce carbon dioxide (CO2), water (H2O), as well as non-toxic gases like nitrogen (N2) and water vapor (H2O (g)). However, it also generates toxic gases such as CO, HC, and Nitrogen Oxides (NOx). Motorcycle exhaust emission tests are commonly conducted using a gas analyzer. In this study, a gas analyser was used to measure the amount of CO, CO2, HC, O2, and NOx emitted from motorcycle exhausts. The tests were carried out using the Vario 160 ABS motorcycle with different types of fuel: RON 92 (S), RON 92 (P), RON 90, RON 98, and RON 92 (R). The data was collected at idle, as well as at 1600 rpm, 1800 rpm, and 2000 rpm. Three measurements were taken for each variable, and the average was calculated. The results showed that RON 98 fuel resulted in better combustion compared to RON 90 and RON 92, as indicated by the CO2 content at idle, which was 13.95%. Additionally, when the motorcycle's engine was throttled, RON 98 fuel did not produce any NOx. The study also revealed that RON 92 (S) fuel led to better combustion compared to both of RON 92 (P) and RON 92 (R), as evidenced by the CO content of 0.05%, CO2 content of 13.63%, HC content of 204 ppm, O2 content of 0.03%, and NOx content of 4 ppm at idle.

Abstract

For numerous decades, diesel fuel has served as the primary source of energy for diesel engines. For optimal performance, these engines are designed to withstand a high flammability threshold. Diesel fuel is therefore the preferable option for refueling military combat vehicles, particularly battle tanks. Concerns have been expressed regarding the use of diesel fuel due to its potential contribution to environmental pollution; emissions from combustion include NO2, NO, CO, SO2, and particulate matter. To reduce these emissions, diesel fuel must be blended with another substance. To reduce emissions, ethanol incorporation is a potential solution. A previous study demonstrated that combining fuels with high and low boiling points can enhance performance. Mixing ethanol, which has a low boiling point, with biodiesel/diesel fuel and fuel with a high boiling point can produce a superior fuel. Analyzing the characteristics of the fuels produced by merging ethanol with diesel fuel and biodiesel is crucial. This analysis aids in the comprehension of the fuel's physical properties prior to its use in a diesel engine. In this investigation, Indonesian diesel fuel and biodiesel standards are blended with ethanol at 10%, 25%, and 35% (volume) blending ratios. In addition to utilizing FTIR (Fourier Transform Infrared Spectroscopy) for analysis, the objective of this study is to determine the combustion properties of a blend of biodiesel, diesel fuel, and ethanol. Using the American Society of Testing Materials (ASTM) D method, fuel properties such as density, viscosity, cetane index, and distillations are analyzed. The results indicate that increasing the proportion of ethanol in diesel fuel and biodiesel reduces viscosity and density. By integrating ethanol, which has a lower density and viscosity than diesel fuel and biodiesel alone, the fuel properties can be improved. A perfect blend of ethanol, diesel fuel, and biodiesel can increase the quality of fuel, thereby enhancing diesel engine combustion.

Abstract

Indonesia is the largest palm oil-producing country in the world, with a share of 59%. In 2013 to 2023, palm oil production in Indonesia increased by an average of 4.7%. The emergence of waste also increases along with the increase in production. Palm oil mill waste consists of palm oil mill liquid waste (POME), mesocarp fiber, palm kernel shells, and empty oil palm bunches. In this study, waste from palm oil, such as mesocarp fiber and empty fruit bunches, can be used to replace the palm kernel shells. Moreover, the addition of biogas to mesocarp fiber and empty fruit bunches will be used as an addition to replace fuel in boiler.
