Investigation of the Effects of TiO2 and Al2O3 Nanoparticles on Exhaust Gas Temperature in Direct Injection Gasoline Engines

OpenAlex İngilizce

In this study, the effects of Al₂O₃ and TiO₂ nanoparticles on exhaust gas temperature (EGT) in a direct injection gasoline engine were experimentally investigated. The Al₂O₃ and TiO₂ nanoparticles were added to fuel mixtures in concentrations of 3.5 ppm and 7 ppm, and tested at engine speeds of 1500, 2500, and 3500 rpm. The results demonstrate that nanoparticles enhance heat transfer within the combustion chamber, leading to higher combustion temperatures. This translates to greater energy production in terms of combustion efficiency and engine performance. In conclusion, the use of Al₂O₃ and TiO₂ nanoparticles as fuel additives shows potential for improving engine performance and offers a novel approach for controlling exhaust gas temperature.
