“…After upgradation and refining, these pyrolysis oils can be mixed with diesel and used in compression ignition (CI) engines. Many researchers (Alagu & Sundaram, 2018;Doğan et al, 2012;Pradhan et al, 2017;Rajamohan et al, 2021;Sharma & Murugan, 2013;Volli et al, 2014;Yang et al, 2013) have studied this and reported a remarkable increase in brake thermal efficiency. Prakash et al (2013) conducted a thorough study using a CI engine charged with pyrolytic oil obtained from waste wood-biodiesel emulsions and discovered that the BTE of 5%, 10% and 15% blends were higher than that of diesel by 0.5%, 4.75% and 7.4% at maximum load.…”
