Abstract: Abstract Diesel engines are widely used in all fields, releasing hazardous substances such as NOx and CO, resulting in significant environmental emissions, global warming, respiratory disorders, and other concerns. Using Diesel-RK software simulations on a 1-cylinder naturally aspirated diesel engine, the effect of cerium oxide (CeO2) with diesel–tyre pyrolysis oil blends on diesel engine performance of brake torque (BT), brake specific fuel consumption (BSFC), cylinder pressure, sauter mean diameter (SMD), combustion (cylinder pressure and heat release rate), and emission characteristics of carbon dioxide (CO2), particulate matter (PM), and nitric oxide (NO) is investigated. The use of cerium oxide boosted engine torque while lowering brake-specific fuel consumption, according to the results. It was interesting to see how adding 100 ppm cerium oxide to a diesel–tyre pyrolysis oil blend increased maximum cylinder pressure at engine load. In comparison with diesel–tyre pyrolysis oil blends, which may be more hazardous to the environment, adding cerium oxide reduces PM emissions while increasing NO emissions. Because of the increased viscosity, the SMD improves with cerium oxide addition. TO10D80 + NA100 ppm (10% tyre pyrolysis oil biodiesel, 80% diesel fuel, and 100 ppm CeO2) mix outperforms diesel fuel in terms of BT, BMEP, BSFC, cylinder pressure, rise of pressure rate, NO specificity, and PM emissions.
