“…Due to the larger plate exposed surface to the electrolyte, the wet fuel cell causes higher electrode corrosion than the dry fuel cell. The catalyst was added to the water solution as a powder and dissolved [49]. Recently, Soly et al, [50] performed a study to investigate the HHO production rate using dry and wet cells.…”

The excessive use of fossil fuels and the resultant dramatic increase in pollution levels have highlighted the need for a new sustainable and environmentally friendly fuel. Hence, it is necessary to research alternatives to reduce the use of fossil fuels and the emission of greenhouse gases. Utilising oxyhydrogen (HHO) gas has been proven to achieve high engine power output and efficiency with low emissions for spark-ignited internal combustion engines. HHO gas is generated from the electrolysis of water. This paper reviews the recent research findings related to the influencing factors on the production of HHO gas using alkaline water electrolysis involving electrolyte properties, electrolyte concentration, the distance between electrolytes, and the effects of HHO gas on the engine performance and gas emissions. Using an HHO gas blend in a diesel/gasoline engine could be a viable option for lowering GHG emissions and increasing engine efficiency.

“…Great interest in hydrogen-based fuels is gained due to their zero-carbon content and enhanced engine combustion characteristics (Butt et al, 2021;Rajak et al, 2022;Sadiq Al-Baghdadi et al, 2023). A reachable hydrogen source to be produced is water electrolysis which contains hydrogen and oxygen (Baltacioglu et al, 2019;Gad & Abdel Razek, 2021;Ozcanli et al, 2017). The final product of the water electrolysis is hydrogen hydrogen-oxygen (HHO) gas or oxy-hydrogen or brown gas which can be easily combined with diesel fuel combustion as diesel/oxy-hydrogen dual-fuel.…”

Reducing carbon emissions such as carbon dioxide (CO2) and carbon monoxide (CO) from diesel engines struggled with engine performance challenges and fossil fuel limitations. Besides, huge transportation such as ships hardly replaced diesel engines due to the higher thermal efficiency and low operation cost. Oxy-hydrogen gas, as a carbon-free gas, could potentially improve diesel engine performance and carbon emissions. Most of the studies tried to identify the effect of oxy-hydrogen induction into diesel engine combustion on performance and emissions. However, this study evaluated oxy-hydrogen injector sizes to the diesel engine performance and carbon emissions at several loads and several engine speed conditions. Overall, the result showed that the oxy-hydrogen gas injection into the diesel engine’s intake port improved the performance and carbon emissions compared to the single diesel fuel as a baseline. High engine performance with low carbon emissions could be achieved at low and medium engine load conditions with high engine speeds. Moreover, smaller oxy-hydrogen injector sizes were suitable for the medium engine load and vice versa, to improve the performance and carbon emissions. At low load, the engine performance improvement of engine torque, specific fuel consumption, and thermal efficiency were 1800 to 2200 rpm. Moreover, the CO2 and CO emissions reductions were also suitable with 2200 rpm with a bigger oxy-hydrogen gas injector (6 mm). Furthermore, at medium load, the engine performance improved at 1400 rpm but the CO2 and CO emissions were lower at 2200 rpm with a small oxy-hydrogen gas injector (4 mm). The engine operation at 2200 rpm with a 4 mm injector also improved the engine performance regarding carbon emissions reduction. However, injecting oxy-hydrogen gas into diesel engines had the potential to enhance the engine performance and reduce carbon emissions, moving closer to achieving zero emissions

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%.
