“…This show that ethanol and methanol added can correct the combustion process because oxygen content is higher than gasoline [14,15], there is NOx can be produced at high-temperature combustion and its production is more than without ethanol and methanol added. A high temperature is an indication that the more gasoline is converted into heat or in other words, the higher the thermal efficiency.…”

The energy demand for fuel is increasing as the vehicle population increases. Until 2035, it is projected that energy use will still be dominated by fossil energy. This needs to be addressed to diversify the use of energy which should be renewable energy (RE) to get a larger portion than at this time, RE has only utilized 5% of all fossil energy used. The higher the use of fuel, the emission of combustion gases is one of the impacts that will accompany it. So, it is necessary to look for renewable and environmentally friendly energy. Ethanol and Methanol are alcoholic chemical compounds, which contain hydrocarbons that can be used as fuel. This study looks for the fuel consumption, emissions, and performance resulting from the use of Ethanol and Methanol as a gasoline fuel mixture in the passenger car. The method used is UN-ECE R101 for fuel consumption and UN-ECE R83 for emission tests. The based and comparison fuel used is gasoline with RON 90 produced by PT. Pertamina and the mixture used is GEM. The car used is Toyota Kijang LGX. As a result, fuel consumption is still better using based fuel with a difference of 18% decreased from M1010. Meanwhile, for cleaner emissions, GEM has reduced CO and HC levels, respectively 43% in E15M5 blend, than 18% in E10M10, while NOx increased by 30% in E10M10 and E15M5 blend. The performance result is GEM better than based.

“…175 Assessing the indicated trends in engine building, it is important for fuel manufacturers to understand how the requirements for gasoline quality indicators will change, primarily for its knock resistance. 176 On the one hand, the extensive development of direct injection and turbocharging technologies is constrained by the actual compression ratio of engines. Moreover, accordingly, an increase in the knock resistance of produced gasoline would further increase the compression ratio and efficiency of new internal combustion engines.…”

The development of oil refining in advanced nations is mostly focused on low-carbon fuel. Similar efforts are being made to improve the fuel efficiency of internal combustion engines, which will result in lower exhaust emissions. Furthermore, by assessing the indicated trends in engine building, it is important for fuel manufacturers to understand how the requirements for gasoline quality indicators will change, primarily for its knock resistance. The aim of the current comprehensive article is to study the state-of-the-art review emphasizing recent progress and prospects for producing high-octane gasoline fuel toward market development. The market for branded gasoline and multifunctional additives, involving friction modifiers, corrosion inhibitor components, as well as detergent components is presented. Furthermore, market development trends and quality requirements for motor gasoline, involving antiknocking characteristics and gasoline oxygenated compounds as additives, are exhibited. Besides, perspective gasoline engine technologies, including different types of engines, are declared. The formulation of effective gasoline surrogates is a challenging task due to advanced combustion strategies, engine design, and variable operating conditions in spark-ignition engines. The extensive development of direct injection and turbocharging technologies is constrained by the actual compression ratio of engines. Likewise, an increase in the knock resistance of the produced gasoline would further increase the compression ratio and efficiency of new internal combustion engines.

“…Methanol has a RON value of 129-134, Oxygen content of 49.9 %-mass, a vapor pressure of 32.2 kPa, and a Lower Heating Value (LHV) of 26,1 MJ/kg. On the other side, ethanol has a RON of 109, an Oxygen content of 34.7 %-mass, a Vapor pressure of 17.2 kPa, and a Lower Heating Value (LHV) by 27.0 MJ/kg (Aghahossein Shirazi et al, 2019;Calvin et al, 2022). With a high RON value, the addition of methanol and ethanol can also be used as mixed components to increase the RON of gasoline (Octane Booster).…”

“…In general, adding methanol and ethanol results in a linear increase in octane numbers and oxygen content (Calvin et al, 2022). The use of ethanolgasoline and methanol-gasoline fuel blends causes to decrease in CO and unburned HC emissions significantly, this is due to improving combustion process as a result of oxygen content in ethanol and methanol (Canakci et al, 2013).…”

Alcohol has the potential to be used as an alternative to fossil fuels to reduce total emissions from spark-ignition (SI) engines. The impact of a mixture of 20% methanol and ethanol in gasoline on the compatibility of Ethylene Propylene Diene Monomer (EPDM) and polyamide materials, which are used as fuel hoses in SI vehicles, is presented in this study. The immersion test methodology was employed to study the influence of both types of alcohol on gasoline blend to compatibility properties i.e., hardness and weight change. Based on the result, EPDM and polyamide materials have different characteristics of material compatibility with E20 and M20. Tests on M20 and E20 fuel samples on EPDM material show a higher effect on hardness by 5-9% than pristine gasoline. Additionally, there was no change in the weight of the polyamide material in the RON 90, E20, and M20 test samples. However, there was a change in the hardness of the polyamide material by 6-11% in RON 90, E20, and M20 fuels. Moreover, there was no change in the FTIR spectrum, indicating that there was no dissolution of the EPDM and polyamide materials into the test fuel for 6 weeks of immersion.
