Enviro-Economic Assessment of HHO–CNG Mixture Utilization in Spark Ignition Engine for Performance and Environmental Sustainability

Road transportation has received the attention of researchers due to its higher carbon footprint. Alternative fuels present major advantages in terms environmental sustainability. For this reason, an enviro-economic analysis alternative carries great significance. However, scarce attempts have been rendered order ascertain impact a hydroxy gas (HHO) and compressed natural (CNG) mixture on sustainable development. The current study addresses issue by employing HHO–CNG gasoline spark ignition (SI) engines for purposes performance pollutants measurement. Then, engine emission data were substituted Weibull distribution establish suitability 50 95% confidence intervals (CIs). outperformed brake-specific fuel consumption (BSFC) contents. On average, with CNG produced 10.59% lower oxides nitrogen (NOX) comparative gasoline. Finally, also turned out be favor owing saving 36.14% USD/year 27.87% production dioxide (CO2) emission.
