Abstract

Waste cooking oil is an attractive feedstock for biodiesel production because of its low cost and availability. This research delved into the viability of utilizing waste cooking oil at varying blend ratios 10%, 15%, and 20% in conjunction with different levels of hydrogen enrichment (3 lit/min, 6 lit/min, and 9 lit/min) for a CRDI single-cylinder diesel engine. The study meticulously examined the impact of combustion parameters, specifically injection pressure (IP), hydrogen (H2) infusion, and waste cooking oil (WCO) inclusion. In terms of both performance and emission considerations, the investigation aimed to optimize these crucial combustion parameters. This was achieved through the implementation of a response surface methodology (RSM), with the primary objective of minimizing emission levels while maximizing engine performance. The emission aspect took into account notable reductions in key characteristics, including carbon monoxide (CO), nitrogen oxides (NOx), smoke, and hydrocarbon (HC) concentrations in the engine exhaust gases. Simultaneously, the performance facet entailed a discernible enhancement in fuel economy and an impressive 8-9% increase in Brake Thermal Efficiency (BTE).
