Waste plastic materials being non-biodegradable, can be suitably processed using pyrolysis to obtain liquid fraction which has properties like petroleum fuels. 20% plastic oil (PO) blends with diesel may be utilized in diesel engines. However, adding biodiesel by 20% being renewable in nature reduces emissions. In the present work 20% PO and 20% biodiesel blend is considered to access the impact of injection timing on the engine performance. Engine tests were performed at four different injection timing 23<sup>0</sup>, 21<sup>0</sup>, 19<sup>0</sup>, 25<sup>0</sup> and 27<sup>0</sup> before TDC. The blend (PO20+60D+B20) showed improved performance with advancing of injection timing with higher in-cylinder pressures and rapid heat release rate. Retarding the injection timings results in early combustion before the working stroke which reduces thermal efficiency. Further retarded IT of 19<sup>o</sup> bTDC results in lower in-cylinder pressures which lead to reduced engine performance. However, advancing IT to 21<sup>0</sup> improvements in engine performance with higher BTE, and lower emissions of HC, CO, and Smoke respectively with higher NOx.</p>}, number={2}, journal={Journal of Advanced Research in Fluid Mechanics and Thermal Sciences}, author={Gollahalli Siddagangappa Jatadhara and Tumkur Krishnamurthy Chandrashekar and Nagaraj Ramalingayya Banapurmath and Nagesh Sampige Basavaraju and Keerthi Kumar Nagaraja Setty}, year={2023}, month={Jan.}, pages={73–84} }
