Analysis of DI CI engine fueled with neat plastic oil and titanium oxide nanomaterial as an additive

The experimental investigation is carried out in a DI CI engine with a constant compression ratio of 17.5 using neat plastic oil and nano-additives, and a comparative analysis is analyzed using neat diesel fuel. The combustion characteristics on peak in-cylinder pressure and ignition delay are analyzed, while emission parameters such as CO and HC are analyzed using diesel, PO, POAL100, POAL150, and POAL200. The in cylinder pressure using different concentration of 100, 150 and 200 ppm of titanium oxide nanoparticle in neat plastic oil is improved 1.52, 3.25, and 3.44%, respectively than neat plastic oil. Results showed that the influence of nano-additive with plastic oil improved the in-cylinder pressure and ignition delay while compared to neat diesel. Similarly, the emission parameters such as CO and HC are significantly reduced by the addition of nano-additive with neat plastic oil. The CO is reduced by 9.3, 16.27, 34.88, 51.16% using PO, POAL100, POAL150, and POAL200 than neat diesel fuel in the engine.
