“…Output power increased with ethanol blends, and emissions decreased significantly, demonstrating the potential of ethanol blending to enhance gasoline engine performance and reduce emissions. Sahil [12] The study investigates ethanol blends with gasoline as an alternative fuel in a spark ignition engine, focusing on engine performance improvement and exhaust emissions reduction. Parameters such as BHP, total fuel consumption, brake thermal efficiency, air-fuel ratio, volumetric efficiency, heat balance, and emissions are analyzed for E10, E20, and gasoline blends at loads of 2kg, 5kg, and 10kg.…”

Finding substitute fuels has been more popular in recent years as a response to escalating pollution levels and fuel shortages. The goal of this research is to find the ideal gasoline to ethanol ratio that will maximize engine performance and reduce emissions in spark ignition engines. In order to analyse the performance of different blending ratios, the research looks at metrics such carbon monoxide (CO) emissions, brake power (BP), brake specific fuel consumption (BSFC), and brake thermal efficiency (BTE). Blends of gasoline and ethanol with a 15% ethanol content greatly increase engine thermal efficiency at higher engine speeds. E12 mixes of gasoline and ethanol boost engine braking power while lowering CO emissions and breakspecific fuel usage. Blends of gasoline with ten to fifteen percent ethanol present a possible substitute.

The objective of this article is to evaluate, through an experimental and numerical study, the effect of the addition of isooctane on the performance and Nox emissions of a spark–ignition engine four different mixtures in addition to gasoline were tested in a spark–ignition engine using the DIN70020 standard at full load. The tests were conducted by adding 10, 20, 30, and 40% isooctane by volume to unleaded commercial gasoline. This practice makes a significant contribution to improving engine performance, increasing fuel efficiency, and reducing pollutant emissions. As a result, the addition of isooctane is establishing itself as a standard in the manufacture of premium fuels, providing not only an improved driving experience but also preserving the health of the engine. Extensive studies have been conducted to explore the potential of isooctane as a fuel in this regard. NOx emissions were reduced by adding a proportion of isooctane to unleaded commercial gasoline for all fuel blends, which could be explained by the high vaporization enthalpy of isooctane. This reduces the maximum temperature reached in the cylinder and thus reduces nitrogen oxide (NOx) emissions. A significant reduction in emissions of approximately 5% is achieved for the I10 blend (10% isooctane + 90% unleaded commercial gasoline) with the maintenance of engine performance (torque and power). This experimental study is confirmed by a numerical simulation using the DIESL-RK software with an average convergence of results that varies from 0.47% to 5.01%.

Many studies focusing on the composition of gasoline with any type of fuel additives have shown that the overall engine performance has a significant impact on reducing emissions. In this research work, ethanol, isopropanol, and diisopropyl ether as oxygenated additive with cerium oxide (CeO2) and iron(III) oxide (Fe2O3) as metal nanoparticles were combined with pure gasoline. Due to the more oxygen they have in their structure, these alcohol additives reduce pollutants and complete combustion. Metal nanoparticles also improve the performance of the engine due to the proper potential. To check the efficiency of the new fuel, a four-stroke engine connected to a dynamometer and an analyzer tested different conditions: speed of 1500 and 2000 rpm and loading percentage of 30 and 40%. Analyzed data include the engine power, and the amount of CO, CO2, HC, and NOx released. The power of the engine on gasoline fuel was 14.43 at 1500 rpm, and once the test was repeated with mixed fuel with additives, it increased to 17.5, which indicates an improvement in engine performance. The amount of CO emissions at 1500 rpm with gasoline fuel was 3.25, and once repeating the test with the same engine rpm with mixed fuel, it decreased to 1.68. The amount of CO2 at 1500 rpm with gasoline fuel was 3.8 and repeating the test with mixed gasoline, it was 5.7. The amount of HC emission with gasoline was 65, and it was 62 when tested with mixed fuel. The amount of NOx released in comparison of gasoline fuel with mixed fuel reached from 264 to 533. The performance improvement and pollutant emissions are fully described in the conclusion section. The analyzed data were calculated and transformed into a model. Among the additives used, isopropanol and CeO2 nanoparticles had better results in optimizing the fuel, reducing the pollutants, and increasing the engine performance. The optimization results show that the use of isopropanol (5%) and CeO2 (1.39 wt. %) as well as diisopropyl ether (4 wt. %) at high engine speed (1504.97 rpm) can be improved engine performance and reduce exhaust gas emissions.
