This abstract encapsulates the essence of the research paper focusing on the design, development, and testing of an HHO (Hydrogen-Hydrogen-Oxygen) generator. The study aims to investigate the feasibility and efficacy of HHO technology in producing hydrogen gas for various applications, including engine decarbonization, renewable energy production, and industrial processes. The research begins with an in-depth exploration of HHO generation principles, electrolysis techniques, and system components. Through systematic design and engineering processes, a prototype HHO generator is developed, integrating innovative features to enhance efficiency, safety, and reliability. Experimental testing is conducted to evaluate the performance of the HHO generator across a range of operating conditions. In this study, we explore the utilization of oxy-hydrogen gas (HHO) as an supplementary source for internal combustion engines. The electrolysis process of water with an electrolyte (such as KaOH) produces HHO gas, which can address fossil fuel shortages and mitigate environmental pollution.
