Individuals are exploring alternative fuels like biodiesel due to energy scarcity and environmental concerns. Biodiesel provides benefits such reusability, environmental friendliness, and recyclability. However, biodiesel’s lower calorific value and greater density might cause the engine to take longer to start, consume more gasoline, and emit more NOx. The highest heat release rate (HRR Max ) of GAB 10 , GAB 20 and GAB 30 was cut by 11.53, 13.59 and 16.47%, respectively. The heat release rate (HRR Max ) values of GAB 10 , GAB 20 and GAB 30 blends are 4.33%, 4.05%, and 1.39% higher, respectively, than GAB fuel when used in an 18.5 CR engine. The HRR Max of GAB 10 T, GAB 20 T and GAB 30 T increases by 3.46%, 2.7%, and 2.27%, respectively, compared to GAB gasoline when the engine compression ratio is 18.5. When nanoparticles were added to clean diesel fuel, the manner it burned improved, particularly at a compression ratio (CR) of 16.5. The stretching vibration of C = O esters is shown by the peaks at 1744 and 1742 cm-1. Peaks at 611 cm-1 indicate the presence of a strong C-Br stretching halo complex. Peaks at 547 cm-1 represent Al-O-Al. Ti-O is represented by peaks at 431 cm-1. Nanotechnology has grown in importance in recent decades because to its obvious advantages in a variety of fields, including environmental clean-up. When nano compounds were utilised, the time it required to ignite the fuel was reduced, resulting in a shorter burning period. NO x emissions from Al 2 O 3 and TiO 2 nanoparticles are reduced by 5.5% and 3.6%, respectively, as compared to their respective biodiesel mixes. The nan additions effectively reduced NOx emissions at peak load. As a result of breakdown of NOx a harmful gas to CO 2 led to an slight increase in carbon dioxide emissions into the atmosphere. Simultaneously, there has been a substantial reduction in particulate matter pollution.
