Feasibility study of neat plastic oil with TiO2 nanoadditive as an alternative fuel in internal combustion engine

This work presents the feasibility study of utilizing neat plastic oil TiO2 nanoparticle is added as additive in the proportion of 100, 150, and 200 ppm fuelled in a stationary single cylinder diesel engine to asses the performance, emission and combustion characteristics. From the local municipality, the waste plastic bottles are collected and it it fed into the pyrolysis reactor to convert into pyrolysis oil. The results from performance analysis revealed that the enrichment of neat plastic with TiO2 nanoparticle enhanced the brake thermal efficiency than without any additives in the raw oil (plastic oil). Similarly, the results of emission revealed that smoke, and hydrocarbon are considerably reduced with increased proportion of nano additive. Results also revealed that the formation of NOx is higher with POAL200 than plastic oil and other concentration of TiO2 nanoparticle and diesel fuel. This is due to the higher availability of oxygen content in the fuel, higher quality of fuel and reduced ignition delay.

Automated summary

The study demonstrates that the use of neat plastic oil with TiO2 nanoparticle additives can enhance the efficiency of a diesel engine and decrease emissions. Increasing the concentration of nano additives leads to a significant reduction in smoke and hydrocarbon emissions.
