Abstract

This study was conducted to improve errors such as low-temperature heat release, ignition delays, and exhaust emissions that occurred during the mechanism reduction process. To achieve this, the error of the reduced mechanism was improved by modifying the A-factor of the important reaction in the selected combustion process through the analysis of the reaction path of 0D CVC. As a result of the 3D CFD analysis, the NOx error rate of the improved mechanism decreased from 92% to 14%, the ignition delay error decreased by 2% on average, and the low temperature and NTC regions, which were the key targets, decreased by 6%.
