Summary: Nanofluids, dispersed in base fuels, have attracted attention for their improved thermo-physical properties. Advances in nanotechnology have led to research on the combustion behavior, stability features, engine functioning metrics, and emission characteristics of nanoparticle-based fuel blends in traditional diesel engines. Despite the advantages, there is ambiguous and inconsistent data in the literature, and there is no shared agreement on the methodology of using nanoparticle-based fuels.

Summary: This study investigates the effect of iron nanoparticles additive on the emissions of a diesel engine in low temperatures and cold start conditions. The results show that the addition of iron nanoparticles reduces the viscosity of the fuel, enhances combustion efficiency, and reduces pollutant emissions.

Summary: The addition of cerium dioxide (CeO2) nanoparticles to diesel fuel can effectively reduce pollutant emissions from compression ignition engines. The experimental investigation of this study showed that the supplement of CeO2 decreased fuel consumption, increased thermal efficiency and exhaust gas temperature. It also reduced hydrocarbon, carbon monoxide, and smoke emissions, while increasing nitrogen oxide emissions. The optimized CeO2 quantity and engine load were determined as 100 ppm and 12 Nm, respectively, resulting in improved combustion performance.

Summary: Effects of adding multi-walled carbon nanotube (MWCNT) to waste frying oil biodiesel (B20) on engine performance and emissions were investigated. The results showed that MWCNT improved fuel properties and reduced emissions of hydrocarbon, CO and soot. However, it also led to increased NOx emissions.

Summary: Dwindling air quality and fossil fuel reserves have prompted the need for alternative fuel sources. Biodiesel from animal/plant sources appears to be a viable substitute, although it has some drawbacks. One potential solution is the use of nano-based biodiesel in internal combustion engines, with the addition of Titanium oxide nanoparticles. This study shows that the nanoparticle-based blended biodiesel has significantly reduced emissions compared to diesel fuel.

Summary: Diesel fuel is efficient, durable, and profitable, but it is a major source of airborne pollutants. Biodiesel has been developed as a potential replacement, but its combustion has drawbacks, especially in nitrogen oxide emissions. Nanotechnology has shown promise in improving biodiesel combustion and reducing emissions, but there are challenges to overcome.

Summary: Experimental and numerical investigations were conducted to study the effects of adding different concentrations of alumina Nano particles to castor oil biodiesel in diesel engines. The results showed that adding 25 ppm of Al2O3 to 20% CME biodiesel significantly reduced fuel consumption rate and emissions concentration. The best reduction in smoke opacity and NOX emissions was achieved with the addition of 25 ppm Al2O3.

Summary: This study investigates the combined synergetic influence of H2O2 emulsification and the addition of multi-walled carbon nanotubes (MWCNT) on the exhaust emissions and performance of a compression ignition engine. The results show that increasing the concentrations of H2O2 and MWCNT has a positive effect on reducing CO, HC, and smoke emissions, as well as improving brake thermal efficiency and reducing brake specific fuel consumption. However, the increase in MWCNT concentration leads to an increase in NOx emissions, while H2O2 emulsification has an inhibitory effect on NOx.

Summary: The use of biodiesel in CI engines has the potential to reduce carbon and hydrocarbon emissions, but it also leads to increased NOx emissions. Recent research has shown that hydrogen peroxide and CeO2 nanoparticles can help reduce emissions in biodiesel blends. Increasing the concentration of hydrogen peroxide improves combustion and reduces CO, HC, and NOx emissions. The concentration of CeO2 nanoparticles also has a positive impact on emissions and brake thermal efficiency, although its effect is not as significant as hydrogen peroxide emulsification.
