Investigation of performance of 0 D internal combustion engine simulation codes based on detailed and reduced chemical kinetic mechanisms
In this study, combustion performance of two 0 D engine simulation codes, Chemkin Pro and SRM Suite, was examined in a homogenous charged compression ignition (HCCI) engine and comparisons were made against the experimental data, which was based on combustion of TRF 70 (70% toluene and 30% n heptane in vol. basis) Reduced and semi detailed chemical kinetic mechanisms of TRF 70 were used in both codes for performance evaluations in terms of pressure, heat release rate and exhaust gas emissions (CO, CO2 and O2) OH and H2O2 emissions, which were difficult to obtain experimentally, were compared computationally among codes using both semi detailed and reduced mechanisms. Both codes had advantages over the other; stochastic reactor model (SRM) resulted in better results than Chemkin Pro in terms of pressure and heat release rate when compared to experimental data, while Chemkin Pro was advantageous owing to its shorter CPU time with acceptable proximity to experimental data.
