TL;DR: In this paper, a performance evaluation of conventional petrol engine by using HHO gas as a supplementary fuel is presented. But the problem related to the storage of hydrogen gas confines the application of pure hydrogen in petrol engine.
Abstract: Considering the current scenario of petroleum fuels, it has been observed that, they will last for few years from now. On the other hand, the ever increasing cost of a gasoline fuels and their related adverse effects on environment caught the attention of researchers to find a supplementary source. For commercial fuels, supplementary source is not about replacing the entire fuel, instead enhancing efficiency by simply making use of it in lesser amount. From the recent research that has been carried out, focus on the use of Hydrogen rich gas as a supplementary source of fuel has increased. But the problem related to the storage of hydrogen gas confines the application of pure hydrogen in petrol engine. Using oxy-hydrogen gas (HHO) generator the difficulties of storing the hydrogen have overcome up to a certain limit. The present study highlights on performance evaluation of conventional petrol engine by using HHO gas as a supplementary fuel. HHO gas was generated from the electrolysis of water. KOH solution of 3 Molar concentration was used which act as a catalyst and accelerates the rate of generation of HHO gas. Quantity of gas to be supplied to the engine was controlled by varying amount of current. It was observed that, engine performance was improved on the introduction of HHO gas.

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%.

Abstract: Air pollution is fast becoming a serious global problem with increasing population and its subsequent demands. This has resulted in increased usage of hydrogen as fuel for internal combustion engines. Hydrogen resources are vast and it is considered as one of the most promising fuel for automotive sector. As the required hydrogen infrastructure and refueling stations are not meeting the demand, widespread introduction of hydrogen vehicles is not possible in the near future. One of the solutions for this hurdle is to blend hydrogen with methane. Such types of blends take benefit of the unique combustion properties of hydrogen and at the same time reduce the demand for pure hydrogen. Enriching natural gas with hydrogen could be a potential alternative to common hydrocarbon fuels for internal combustion engine applications. Many researchers are working on this for the last few years and the work is now focused on how to use this kind of fuel to its maximum extent. This technical note is an assessment of hydrogen enriched compressed natural gas usage in case of internal combustion engines. Several examples and their salient features have been discussed. Finally, overall effects of hydrogen addition on an engine fueled with hydrogen enriched compressed natural gas under various conditions are illustrated. In addition, the scope and challenges being faced in this area of research are clearly described.

Abstract: Nowadays, more researches focus on protecting the environment. Present
investigation concern with the effectiveness of Oxygen Enriched hydrogen- HHO
gas addition on performance, emission and combustion characteristics of a DI
diesel engine. Here the Oxygen Enriched hydrogen-HHO gas was produced by the
process of water electrolysis. When potential difference is applied across
the anode and cathode electrodes of the electrolyzer, water is transmuted
into Oxygen Enriched hydrogen-HHO gas. The produced gas was aspirated into
the cylinder along with intake air at the flow rates of 1 lpm and 3.3 lpm.
The results show that when Oxygen Enriched hydrogen-HHO gas was inducted, the
brake thermal efficiency of the engine increased by 11.06%, Carbon monoxide
decreased by 15.38%, Unburned hydrocarbon decreased by 18.18%, Carbon dioxide
increased by 6.06%, however, the NOX emission increased by 11.19%.
