“…The authors also investigated the effect of this surfactant on gasohol E5, E10, E15, and E20. The study found that the surfactant increased the phase stability of emulsions [19,20]. The study, however, did not inform about the temperature range in the blending process and the ethanol concentrations employed were limited to 96 % and absolute ethanol.…”

Many countries worldwide encounter the greatest difficulties in improving people's life quality since fossil fuel reserves are decreasing, causing fuel prices to rise drastically. This problem has made many countries, including Indonesia, struggle to import them from producers in the Middle East. Adding a small part of ethanol to gasoline is one of the solutions that has been investigated and developed. The previous works relating to blended fuels, gasoline and ethanol, generally employed absolute alcohol, which was expensive. A small surfactant was added to the mixture to stabilize the emulsion, and the blending was conducted in normal conditions (room temperature). If the composition of gasoline and aqueous ethanol is not precise, the components can be separated at a specific temperature. The present study is aimed to report the analysis of compositions and fuel specifications of aqueous emulsions of gasoline (RON 90)-ethanol-water in a single phase without using a synthetic surfactant in the temperature range of 0–25 °C. The procedures were as follows: fermentation, ethanol distillation and purification, cooling, blending, and characterization of fuel specifications. Components of gasoline (RON 90)-ethanol-water formed a stable emulsion in the composition range of 28.00‒99.79 %, 0.20‒67.97 %, and 0.01‒3.58 %. The observation found that continually increasing the amount of aqueous ethanol and temperature after one phase was attained would not lead to the separation of components. Therefore, gasoline and aqueous ethanol can form a single phase functioning as a surfactant binding water and fossil fuel. The decrease in temperature after the emulsion is stabilized can separate the components whereby it is caused by the faster density change of aqueous ethanol than gasoline

“…Changes in parameter E70 of gasoline with added FT naphtha as well as changes in vapor pressure result in a decrease in the volatility index. Due to the very low vapor pressure of pure FT naphtha, it is important to know the temperature dependence of gasoline mixtures with FT naphtha, since a certain minimum volatility of gasoline with a minimum vapor pressure of 5 kPa is required for a cold engine start [31,32]. This is the lower limit of the starting ability.…”

The aim of the article is to determine the properties of fuel mixtures of Fischer–Tropsch naphtha fraction with traditional gasoline (petrol) to be able to integrate the production of advanced alternative fuel based on Fischer–Tropsch synthesis into existing fuel markets. The density, octane number, vapor pressure, cloud point, water content, sulphur content, refractive index, ASTM color, heat of combustion, and fuel composition were measured using the gas chromatography method PIONA. It was found that fuel properties of Fischer–Tropsch naphtha fraction is not much comparable to conventional gasoline (petrol) due to the high n-alkane content. This research work recommends the creation of a low-percentage mixture of 3 vol.% of FT naphtha fraction with traditional gasoline to minimize negative effects—similar to the current legislative limit of 5 vol.% of bioethanol in E5 gasoline. FT naphtha fraction as a biocomponent does not contain sulphur or polyaromatic hydrocarbons nor benzene. Waste materials can be processed by FT synthesis. Fischer–Tropsch synthesis can be considered a universal fuel—the naphtha fraction cut can be declared as a biocomponent for gasoline fuel without any further necessary catalytic upgrading.

“…Fuel now occupies the top spot on the list of ownership costs for older vehicles that have already undergone substantial depreciation. The majority of automobile manufacturers design nearly all of their engines to operate on Regular grade gasoline in order to help control vehicle operating expenses [15]. However, some engines need or advise using premium gas in order to accomplish the claimed power production and fuel e ciency gures.…”

Internal combustion engine emissions from burning fossil fuels, particularly those from petrol engines, are a major factor in change in the climate and the generation of greenhouse gases. For a long time, ethanol has been noticed as a viable alternative to gasoline that might also help to lower pollution levels. In the current experimentation investigations, the engine performance, combustion, and emission characteristics were assessed for the various ethanol-premium gasohol blends with partial addition of alkane’s such as n-pentane, hexane etc. With addition of hexane and n-pentane in premium gasoline and ethanol blends, carbon monoxide (CO) emission decreased by 18% than premium gasohol. The lowest emission were observed for premium gasoline with 40% ethanol and 10% n-pentane. It was observed that addition of hexane and n-pentane hydrocarbons found to be decreased by 15% as compared to premium gasool. Furthermore, with addition of ethanol blending, cylinder pressure decreased. Both unburned hydrocarbon (HC) and Nitrogen oxides (NOx) increased in spark advancement from 21 to 15° bTDC and became minimum for spark timing 21° bTDC. Again, it increased from spark retardment from 21° to 30° bTDC. This was because there was incomplete combustion takes place. But engine emissions decreased with partial addition of alkanes with premium gasoline and 20% ethanol with spark advancement as well as retardment. The brake thermal efficiency of PG + 10% P were found maximum. The oxides of nitrogen (NOx) were found minimum by 25% with addition of ethanol and paraffin in premium gasoline.
