Abstract: As a result of the significant growth in both the population and transportation, the demand for conventional fuels such as petrol and diesel is growing, leading to depletion of these non-renewable resources. Researchers are exploring alternative fuels that are cost-effective and environmentally friendly, such as biofuels. Biofuels are considered an attractive alternative due to their low toxicity, no sulphur content, reduced emissions, and higher oxygen content. In this study, a combination of biodiesel (B10, B20, and B30) with ceric oxide (CeO2) nanoparticles is used to examine the performance, ignition, and exhaust emissions of a Common Rail Direct Injection (CRDI) compression ignition engine. Biodiesel produced from matured waste ziziphus mauritiana peels oil is considered as aproper alternative to traditional diesel fuel because of its similar physicochemical properties. Nanoparticles are being used to enhance the performance, ignition, and emission characteristics of biofuels. Ceric oxide nanoparticles were mixed with biodiesel blends using a magnetic stirrer. The experiment was carried out using the following biofuel samples: 10% biofuel mixed with 90% diesel (B10), 20% biofuel mixed with 80% diesel (B20), and 30% biofuel blended with 70% diesel (B30), with the addition of 100ppm ceric oxide nanoparticles to each blend (B10, B20, B30). The experimental engine was operated at a constant compression ratio of 17.5:1 and at a continuous speed under different loading conditions (0%, 25%, 50%, 75%, and 100%). The study found that improving the concentration of biodiesel in the blends and adding ceric oxide nanoparticles reduced harmful exhaust gas emissions from the CRDI engine. Increased brake thermal efficiency and lower emissions of carbon monoxide (CO), hydrocarbons (HC), and particulate matter (PM) were the results of the use of ceric oxide nanoparticles, which also enhanced the engine's performance and emission characteristics. However, increasing the biodiesel concentration also resulted in increased nitrogen oxide (NOx) emissions. The study suggests that blending biodiesel with ceric oxide nanoparticles can be a viable alternative to traditional diesel fuel, further inspection is required to properly comprehend the long-term impacts of employing biodiesel mixes containing nanoparticles on engine longevity and emissions.
