“…Exhaust emissions (CO2, HC, and CO) using butanol variations are far more optimal than using gasoline. In contrast to NOx emissions, which increase in the use of butanol because a high octane value results in an increased combustion rate in the combustion chamber [8]. The experiment has combined gasoline (60%v/v) with butanol (40%v/v); the engine operates under WOT conditions and low speed.…”

The availability of fuel oil is decreasing while the level of consumption is increasing. This encourages the need for the development of alternative energy to minimize the crisis. This study investigates the characteristics of fuel and automatic transmission combustion engines. The fuel used is butanol variations B7, B12 and B18 (7%, 12%, and 18%) and pertalite (RON-90). The gasoline engine used has a capacity of 110 cc with a compression ratio of 9.5:1, an automatic transmission system, and air conditioning. The performance test equipment used is the Dynotest-chassis type 50L-BRT. Fuel variations are applied to an engine performance test by using engine speeds of 3000-9000 rpm. The results showed that the use of 18% butanol increased the output power and thermal efficiency by 8.3 kW and 923.95 kPa at 8000 rpm. torque and MEP (average effective pressure) increased by 8 N.m and 923.95 kPa at 5000 rpm. Meanwhile, SFC (specific fuel consumption) decreased by 0.35 kg/kWh at 8000 rpm.

“…Because the percentage of butanol is increasing, torque and power have increased in the butanol mixture below 30% at minimum throttle opening, followed by a decrease in specific fuel consumption. Exhaust emissions experienced a significant decrease in CO, CO 2, and HC, but the opposite occurred in NOx, which increased [11]. Increasing environmental pollution and depleting the amount of fossil fuels, alternative fuels such as ABE needs to be developed in vehicles.…”

Butanol as a fuel has a high oxygen content, so the combustion process will be more friendly to the environment. In this study, butanol will be mixed with RON-90 gasoline with a capacity of 5% (B5); 7%(B7); 10%(B10); 12%(B12); 15%(B15) and 18%(B18). The engine used is an automatic transmission with a capacity of 109.5cc with a compression ratio of 9.5:1. The test equipment for engine performance and exhaust emissions is the 50L BRT Super-Dyno and EPSG4 Gas Analyzer. The results showed that using B18 fuel for CO exhaust emissions decreased by 44% at an engine speed of 6000rpm. CO2 exhaust emissions have decreased by 47% at 8000rpm engine speed. HC exhaust emissions have decreased by 28% at 9000rpm engine speed. In contrast to NOx emissions, which increased by 22% at 9000rpm engine speed, this was due to the increasing temperature in the combustion chamber.

“…These alcohols also have higher combustion efficiencies due to their higher-octane numbers than gasoline. Blending of alcohols with fuels has been shown to reduce the emissions of greenhouse gases and particulate matter upon combustion, while offering engine performance higher or comparable to gasoline. − In addition, the alcohols are liquid at ambient temperature and pressure and can be stored in nonpressurized tanks.…”

Higher alcohols are promising products for large-scale CO 2 utilization due to their potential large volume use as chemical energy carriers and fuel additives. Although the catalysts for these transformations are still in early stages of development, it is advantageous to examine their expected process level performance to guide further scientific progress. Here, we performed prospective techno-economic and environmental evaluations of 1-propanol, 1butanol, 1-pentanol, and 1-hexanol syntheses from captured CO 2 and green H 2 via the syngas route (i.e., CO 2 to syngas to higher alcohol) for the best case (ideal) conversion and selectivity. While 1-pentanol and 1hexanol plants show economic viability, the costs of manufacturing the other two alcohols exceed their respective revenues. In all the four processes, the cost of raw materials, utilities, and wastewater treatment accounts for about 83%, 12%, and 5% of the cost of manufacturing, respectively (neglecting CAPEX). Sensitivity analysis shows that the cost of H 2 has to drop to about 2100 and 1700 $ t −1 from the current level of ca. 2500 $ t −1 for 1-propanol and 1-butanol processes to break even. In all four processes, the fraction of H 2 feed lost to byproduct water ranges from 55 to 60%, which is an inherent issue with thermocatalytic hydrogenation of CO 2 . Although a standalone green 1-propanol plant is not presently viable, a hybrid process combining a recently studied synthesis route (using ethylene and CO 2 -derived syngas) and the novel route based solely on CO 2 can minimize the carbon footprint without sequestration and also be profitable at the prevailing hydrogen cost.
