Abstract
Climate change, clean air, renewable energy, nontoxic surroundings, and the opportunity to live in a healthy community are just few of the issues that environmental sustainability addresses. To improve environmental health and quality of life, several researchers have turned their attention to alternative energy sources like ethanol and oxyhydrogen. In latest years, significant progress has been made in the development of ethanol and hydrogen as clean energy sources. A higher octane rating is achieved by mixing ethanol with gasoline rather than using regular gasoline. A novel mix of oxyhydrogen, ethanol, and gasoline is ecologically friendly while simultaneously increasing the performance of gasoline engines. In this study, a nanoparticle-coated piston on a low heat rejection gasoline engine fuelled by an ethanol-gasoline mix with oxyhydrogen addition was investigated. It has been evaluated that thermal efficiency improved by up to 25% while fuel consumption can be reduced by up to 28% on a volume basis compared to the baseline engine. Furthermore, the decrease in harmful carbon monoxide reached around 10%, and the reduction in unburned hydrocarbon emissions reached 18%.

An experimental study was performed on a small gasoline engine with a nanocoated piston fuelled by an ethanol-gasoline mix with oxyhydrogen as an additive. ree different blends of ethanol used with a constant volume of oxyhydrogen were blended with gasoline. e results show that, along with ethanol and oxyhydrogen, brake thermal efficiency improved by 23% and 32% at 15% and 20% blends, respectively, due to the boost provided by higher flame velocity and a more diverse spectrum of flames when utilizing oxyhydrogen and ethanol. e combustion rate of ethanol-gasoline was substantially increased when a combination of oxyhydrogen was added
Summary
E impact of a mix of ethanol and gasoline on power, torque, fuel consumption, and emissions was investigated using analytically assessed steady-state engines [3]. E results of several experiments showed little or no response to ethanol concentration up to 10% by volume, suggesting that engine operating circumstances have a more significant impact on engine characteristic and emissions at low-ethanol blend levels. As engine speed increases and the proportion of ethanol in the fuel mix decreases, volumetric efficiency tends to decline. Low-ethanol mixes with less than 20% ethanol had no obvious effect on engine efficiency or torque, but the performance of the engine decreased when the proportion of blending was increased [13]. A mixture of oxyhydrogen, air, and gasoline reduced pollutant emissions and improved engine efficiency significantly [16]. CO emissions were found to be lowered by 20% and fuel consumption was reduced by 25% [17]. e researchers experimented with different hydrogen concentrations
