Effect of camphor oil on a plastic pyrolysis oil fueled DI diesel engine

Abstract

Plastics, as we know have become almost impossible to dispose in today’s times and their use is consistently on the rise. Because of its high heating value and availability, plastic waste can be used as a source of energy. Pyrolysis process will turn this plastic into oil, which can then be employed as fuel in IC engines to generate heat and power. The use of neat plastic pyrolysis oil in a DI engine will result in low BTE and more incomplete combustion. This is due to its high viscosity. This issue can be solved by blending the PPO with camphor oil. The properties of the plastic pyrolysis oil (PPO) were examined and it was found to be similar to diesel. The two fuels were run separately on a 4 stroke, direct injection, single cylinder, diesel engine with a rated power of 5.2 kW at 1500 rpm and a CR of 17.5. The PPO was then blended with camphor oil at 5%, 10%, and 15% by volume and the combustion, emission and performance characteristics studied. It was found that the PPO85C15 blend had the highest brake thermal efficiency and the lowest HC emissions.
