Abstract-

To study the effect of adding hydrogen to diesel fuel on carbon and nitrogen oxide emissions, as well as reducing fuel consumption and improving engine performance, we used the ANSYS simulation program, which is considered one of the most powerful engineering simulation programs. You can use it to analyze the effect of hydrogen in diesel fuel on carbon and nitrogen oxide emissions, as well as to reduce fuel consumption and improve engine performance. The fuel type (diesel + hydrogen) was defined and fuel properties were determined, such as the hydrogen ratio, fuel density, combustion coefficient, adjusting the air-to-fuel ratio, and the effect of mixing - with diesel. After running the program, you will notice that when the hydrogen ratio increases, carbon dioxide emissions decrease and nitrogen oxide emissions increase due to the high combustion temperature and an improvement in fuel efficiency if the ratios are adjusted correctly.

Keywords- hydrogen, diesel fuel, on carbon and nitrogen oxide emissions, fuel consumption
