Comparative analysis of heat release in a reciprocating engine powered by a regular fuel with pyrolysis oil addition

Abstract

The article presents a comparative analysis of heat release rate in a spark-ignition reciprocating engine powered by various fuels as follows: butanol, gasoline, a mixture of butanol with tire pyrolysis oil (TPO), and mixtures of butanol with oil from biomass pyrolysis (BPO). Selected combustion phases were analyzed. Additionally, ignition delay calculations were performed in the ANSYS Chemkin Pro program for the surrogates of the tested fuels. The ignition delay was calculated using the closed isolated homogeneous reactor. Popular surrogates quoted in numerous publications were used as substitute fuels. The paper presents an original four components surrogate of oil from tire pyrolysis.
