Summary: This study investigates the NOx formation mechanism and the influence of parameters in ethanol-gasoline blends used in a GDI SI engine through experiments and chemical kinetic simulation. The results show that in addition to the thermal pathway, pathways involving N2O and NNH have a significant impact on NOx emissions under high engine speed conditions. Initial temperature exacerbates NOx emissions, while initial pressure and ethanol fraction inhibit it. The equivalence ratio (ER) initially promotes NOx formation, but then resists it, with the highest emission occurring at an ER of 0.85. In lean burn conditions, the thermal pathway is highly inhibited, while the N2O pathway is accelerated.

Summary: The increasing human population has led to a significant use of fossil fuels to meet energy needs. While various renewable sources are used as alternatives, they are not effective in replacing traditional non-renewable energy sources like gasoline in vehicles. The depletion of conventional fossil fuels used in vehicles leads to increased air pollution and poses a threat to human health. Therefore, researchers are exploring the possibility of using a higher percentage of ethanol blended with gasoline, with hydrogen assistance, to overcome the problem of knocking and reduce emissions.

Summary: The negative effects of traditional engine fuels on climate change have led to a high level of competition in finding alternative fuels that are more environmentally friendly. Alcohol fuels, particularly ethanol, have been found to be practical for blending with traditional engine fuels like gasoline. Research has shown that blending ethanol with gasoline can increase power, efficiency, and reduce harmful exhaust gases. However, ethanol may have a negative impact on volumetric efficiency, while also improving power and efficiency as its concentration increases.

Summary: In this study, a Y-nanozeolite catalyst was synthesized using hydrothermal method and Iraqi sand-derived silica as raw material. The catalyst was tested before and after being loaded with potassium hydroxide (KOH). The results showed that the conversion and yield increased when the temperature and/or reaction time were increased, especially after promoting the catalyst with 10% KOH. The optimal conditions for achieving the highest conversion and yield of biodiesel were determined to be a temperature of 60 degrees C, a reaction time of 2 h, and the use of a catalyst with a particle size of 75 mu m loaded with 10% KOH.
