This paper provides a comprehensive overview of the physical properties and applications natural gas (NG) hydrogen as fuels in internal combustion (IC) engines. The also meticulously examines use both NG fuel vehicles, their production, characteristics, properties. It reviews current experimental studies literature investigates results using fuels. further covers challenges associated with injectors, needle valves, lubrication, spark plugs, safety requirements for Finally, related to storage, are discussed. review reveals that ignition (SI) engines has clear direct positive impact on economy certain emissions, notably reducing CO2 non-methane hydrocarbons. However, its effect other such unburnt hydrocarbons (UHC), nitrogen oxides (NOx), carbon monoxide (CO), is less clear. NG, which primarily methane, lower carbon-to-hydrogen ratio than diesel fuel, resulting emissions per unit energy released. In contrast, particularly well-suited gasoline due high self-ignition temperature. While increasing content reduces torque power output, higher input reduced consumption mitigation toxic exhaust emissions. Due temperature, not inherently suitable engines, necessitating exploration alternative methods introduction into cylinder. suggests shown reduction specific an increase NOx Overall, valuable informative opportunities IC highlights need research development address remaining challenges, more efficient chambers

An experimental study and ANN analysis of utilizing ammonia as a hydrogen carrier by real-time emulsion fuel injection to promote cleaner combustion

Results in Engineering, Journal Year: 2024, Volume and Issue: 21, P. 101946 - 101946

Published: Feb. 24, 2024

This work utilized Real-Time Emulsion Fuel Injection (RTEFI) methods to incorporate emulsion fuel, which included citronella oil (20%), ammonia (10%), and water (5%), into diesel fuel without the addition of surfactants. The primary aim this study was investigate influence hydrogen presence in liquid on engines. accomplished by using a water-emulsified diesel-biodiesel blend forecasting performance an artificial neural network (ANN). Citronella (20%) blended with standard (SD), followed 10% 5% water, labeled as SD20CO, SD20CO10A, SD20CO10A5W, respectively. results indicated that brake thermal efficiency SD20CO10A5W is comparable diesel. combination significantly decreased hydrocarbon emissions 70–75%, smoke 10–15%, oxides nitrogen 2–5%, while increasing carbon dioxide 3–8% under all load situations compared other fuels. trained ANN models had coefficient determination 97%, values ranging from 0.9076 0.9965. Additionally, exhibited low mean absolute percentage error values, 0.98% 4.26%. analytical provide strong evidence supporting efficacy ultimately indicating it feasible substitute for
