“…The test was conducted in one cylinder of the engine. As reported by [14] MWCNTs-COOH have amide groups that are able to react with many reagents. Multiwalled carbon nanotubes (MWCNTs-COOH) were mixed at 30, 60, 90 ppm with a solution containing 95% diesel fuel and 5% biodiesel (B5).…”

“…A group of particular importance are carbon nanotubes (CNTs), which due to their high magnetic, electrical, optical and thermal conductivity exhibit a significant potential for use as fuel additives to improve performance and reduce emissions of harmful substances. The research conducted in [14] focused on studying the effect of adding multi-walled carbon nanotubes (MWCNTs-COOH) to biodiesel as an admixture to standard diesel fuel. The test was conducted in one cylinder of the engine.…”

Nanomaterials are a new group that has quickly found a wide range of applications in medicine, cosmetology, the food, weapons or automotive industry. They are also used as a fuel additive. This paper reviews the literature and assesses the current state of knowledge regarding the use of nanoparticles in automotive engine fuels. The results obtained so far are presented and further research directions in this field are identified Conclusion: The results of the review showed a discrepancy, selected groups favor the reduction of harmful gas emissions, while others do not and even increase emissions, e.g. the use of carbon nanotubes contributes to the increase in the emission of environmentally harmful nitrogen oxides, while the presence of graphene oxide reduces it. An interesting observation is also the fact that groups such as titanium and graphene oxide reduce the emission of harmful carbon monoxide by improving fuel combustion from semi-combustion to complete combustion, but at the same time increase CO2 emissions, which in turn is a greenhouse gas The whole group of nanomaterials contributes to the reduction of hydrocarbon emissions Nanomaterials improve the quality of fuel combustion The review shows tests only on diesel and a mixture with biodiesel in the review there were no studies for gasoline
