Abstract
This paper explores the auto-ignition chemistry of n-heptane and toluene mixture to represent diesel-homogenous charge compression ignition (HCCI) combustion by means of a reduced chemical kinetic mechanism using CHEMKIN-PRO. In particular, pressure and temperature histories of n-heptane–toluene mixture are demonstrated at the stoichiometric condition and at the lean operating condition with 0%, 10%, and 20% exhaust gas recirculation (EGR) rates, respectively. Since pressure and temperature profiles play a vital role in a reaction path at a certain operating condition, an endeavour has been made here to present a comprehensive reaction path analysis on the formation/destruction of chemical species at a peak operating condition. Also, validation of the proposed model was done by comparing the results with the experimental analysis carried out by prior researchers. Besides, multiple linear regression analysis was performed to compute the pressure and temperature histories of various lean operating conditions (Φ = 0.5–0.9) with and without EGR through the fresh intake stream.
