Sustainable Plastic Waste‐Derived Fuel: Yield Optimization and Performance in Thermal Barrier‐Coated Crdi Engines

This study examines the performance characteristics of a CRDI diesel engine powered by a blend of plastic oil, methanol, and diesel, incorporating a thermal barrier coating. The yield of plastic products was examined across several parameters, including residence time, reaction temperature, and catalyst concentration. According to the experimental findings, the concentration of plastic oil significantly affected emission, performance, and combustion variables. Methanol was added to the P50 blend at different proportions to counteract the reductions. Also, the thermal barrier coating further improved the performance characteristics. Experimental results showed that test fuel P50M20/TBC 1 (Al 2 O 3 + MO) achieved a higher brake thermal efficiency (BTE) and lower exhaust emissions than the other test fuels, except neat diesel. The tests showed that plastic oil could replace diesel fuel at up to a 50% rate and that using methanol fuel and a thermal barrier coating could minimize the adverse effects of using plastic oil.
