In this work, the effects of adding Multi-Walled Carbon Nanotubes (MWCNT) along with leftover cooking oil on a diesel engine's efficiency, emissions, and combustion properties were studied. After TEM examination, using an ultrasonicator, the MWCNT was combined with biodiesel fuel made from leftover cooking oil at concentrations of 0 and 25, parts per million. A constant speed of 1500 rpm was used to test these blends while varying engine loads. The experimental results indicated that the cylinder peak pressure, peak pressure rise rate, and heat release rate were slightly lower when MWCNTs were added to WCO fuel compared to pure WCO fuel. The innovative fuel mix significantly decreased CO and BSFC. Not only that, but the specific fuel consumption was lower than with pure WCO fuel, and the brake thermal efficiency was significantly altered.25 ppm was found to be the proper dose level of MWCNTs with WCO fuel based on engine capability and pollutant comparisons. All engine performance metrics significantly increased as a result.
