Oxygenated nanoparticles influence on internal combustion (IC) engines performance, combustion, and emissions

One possible method to improve engine performance, optimise combustion properties, and lower hazardous emissions is the incorporation of oxygenated nanoparticles as fuel additives in internal combustion (IC) engines. These nanoparticles, typical metal oxides as Al2O3, CeO2, TiO2, and ZnO, enhance combustion through catalytic activity and serve as localised oxygen donors during fuel oxidation. Improved atomisation, quicker ignition, and higher heat release rates are all facilitated by their large surface area and thermal conductivity. According to experimental research, adding such nanoparticles to diesel, biodiesel, or mixed fuels at modest concentrations (usually 30-150 ppm) significantly increases brake thermal efficiency and decreases brake-specific fuel consumption. Due to complete combustion, emission measurements regularly demonstrate notable reductions in smoke, carbon monoxide, and unburned hydrocarbons. Nevertheless, higher in-cylinder temperatures and quicker flame propagation are frequently linked to a little rise in nitrogen oxides (NOx) emissions. All things considered, the application of oxygenated nanoparticles presents a practical solution to enhance fuel efficiency and ecological sustainability in internal combustion engines, especially when combined with biodiesel plus exhaust gas recirculation (EGR) technology.
