Effect of cerium oxide nanocatalyst on performance emissions and noise of diesel biodiesel blends in a variable compression ratio engine.

ABSTRACT: A recent study investigates the impact of adding biodiesel to petrol-diesel fuel blends and the use of catalysts on engine performance and emissions. This work focuses on cerium oxide nanoparticles incorporated into B10 and B20 fuel blends, where B10 consists of 90% diesel and 10% biodiesel derived from waste frying oil. The effects of these nanoparticles at concentrations of 20, 50, and 80 ppm were evaluated using a single-cylinder Variable Compression Ratio (VCR) engine. Tests were conducted at engine speeds of 1,500, 2,000, and 2,500 rpm to measure torque, power, brake thermal efficiency (BTE), specific fuel consumption (SFC), exhaust gas temperature (EGT), and emissions of CO, CO₂, unburned hydrocarbons (UHC), and NOx. The results revealed improvements of 6.43%, 6.46%, 12.78%, and 6.93
