Assessment of Pollutant Emissions in an M2 Vehicle Fueled with Oxyhydrogen-Gasoline Blends Under Static Conditions

Urban air pollution, primarily driven by industrial activities and vehicle traffic, is a pressing global concern. The automotive sector must urgently reduce CO₂ and CO emissions due to their significant impact on climate change and human health. In Latin America, the heavy reliance on fossil fuels exacerbates air quality degradation, highlighting the need for alternative fuel research. This study evaluates the impact of oxyhydrogen (HHO) gas-gasoline blends on the emissions of an M2 vehicle using static tests. A 2023 Cherry Practivan Karry 1.2L equipped with an HHO generator, featuring a wet cell with 316 stainless steel plates and a 1.5% KOH electrolyte, was used. Three HHO flow levels were tested and measured with an MF5712 mass flow meter, under idle (780 rpm) and 2500 rpm conditions. A Brain Bee AGS-680 gas analyzer assessed the emissions of CO, CO₂, and HC. The results demonstrated that blending HHO gas with 87-octane gasoline at a maximum flow of 1.7 slpm significantly reduced HC emissions, while CO₂ levels slightly increased. This research underscores the potential of HHO gas in reducing pollutants and the importance of ongoing optimization to balance emissions, contributing to global efforts in combating air pollution and climate change.
