Abstract

Tire pyrolysis oil (TPO) represents a promising waste-derived fuel for Diesel engines with its main deficiency being lower cetane number compared to Diesel fuel. Until now, successful utilization of the TPO in Diesel engines was possible only by increasing its cetane number, increasing compression ratio of the engine or preheating intake air or operation. This study shows the foremost results of utilizing the pure TPO in a modern turbocharged and intercooled Diesel engine without any of the aforementioned aids, which significantly facilitates its use and boosts its conversion efficiency to mechanical work. This was achieved by the tailored injection strategy that includes pilot injection, which was previously not utilized in combination with the TPO. The study reveals that with additional tailoring of the pilot injection, further optimization of thermodynamic parameters can be achieved while operating the turbocharged and intercooled Diesel engine in a wide operating range under the use of pure TPO. Discovered phenomena are supported by interpretation of interactions between the injection parameters and combustion as well as emission formation phenomena of the pure TPO.
