Abstract

The numerical simulation of an internal combustion engine's combustion chamber serves as an effective strategy for enhancing the engine's performance and minimizing pollutant emissions. This study initially formulated a skeletal reaction mechanism for the coupled generation of Polycyclic Aromatic Hydrocarbons (PAHs) in F-76 and HRD-76 fuels. The efficacy of this skeletal mechanism was validated through combustion characteristics such as ignition delay time and laminar flame speed. Subsequently, a simulation research platform for the internal combustion engine was established, grounded on the real engine model and integrated with the skeletal mechanism. The simulation model's reliability was authenticated through cylinder pressure. Lastly, an exhaustive analysis was carried out on the in-cylinder combustion characteristics and PAHs generation patterns of the two fuels. The findings indicate that HRD-76 fuel generates a higher quantity of A2 and A3 compared to F-76 fuel. However, F-76 fuel produces a larger amount of A4, with an earlier generation time.
