| Abstract | Waste cooking oil -based biodiesel gained profound attention owing to its high calorific value and energy content. Recycling the waste cooking helps the circular economy in the perspective of sustainable energy production. Production of the energy from the waste materials can help to reduce the environmental burden. A single cylinder diesel engine used to determine the effect of the waste cooking oil on the diesel engine when they are blended with the energy fraction of hydrogen and ammonia. The flow rate of hydrogen and ammonia maintained constant throughout the entire study. The fuel scheme was 20% biodiesel tested along with 10 LPM of hydrogen and 10 LPM of ammonia. The influence of waste cooking oil blends on brake thermal efficiency (BTE), Brake specific fuel consumption (BSFC), and emissions were examined for wide range of engine loads. The incorporation of a 20% waste cooking oil blend reveals a consistent decrease in brake thermal efficiency across all engine loads due to high latent heat of evaporation. Conversely, blends with waste cooking oil, ammonia, and hydrogen exhibit increased BTE, emphasizing positive contributions to the combustion process. The introduction of TiO 2 nanoparticles yields two different outcomes based on the engine loading conditions. BSFC analysis reveals challenges in fuel efficiency with WC20, while the addition of ammonia, hydrogen, and nanoparticles reduces the overall BSFC. Emission assessments showcase reductions in CO, HC, and smoke emissions, with notable challenges in mitigating NOx emissions. Ammonia helps to reduce the carbon content in the fuel which resulted in lower CO and HC formation during combustion. |
