Assessing Engine Dynamics, Fuel Efficiency, and Emission Characteristics with HHO-Enriched Fuel: A System-Level Evaluation of a HydroBoost™ Technology

<div>In the present work, the effect of HHO addition to gasoline was investigated using HHO produced via the HydroBoost™ electrolysis technology—a system specifically designed to overcome the limitations of conventional electrolysis methods, such as electrode degradation, low efficiency, and safety concerns. Engine performance, fuel behavior, and emission characteristics were evaluated both with and without HHO enrichment. A comprehensive four-phase testing protocol was adopted to simulate various real-world driving conditions. Through a multi-parameter assessment—including fuel economy (FE), engine response under different load conditions, fuel savings accounting for parasitic load, total volatile organic compounds (TVOC), and greenhouse gas (GHG) emissions—it was demonstrated that HHO addition significantly enhances both the performance and emission characteristics of a gasoline-powered internal combustion engine. Statistical significance of these parameters was assessed across four phases, with five of the seven parameters found to be significant. Combustion enhancement leads to reduced fuel mass consumption and improved energy utilization, demonstrating an overall improvement in system efficiency, while maintaining mass balance. These findings are particularly important as they validate the real-world viability of using HHO produced from an improved and safer electrolysis system.</div>
