Homogeneous Charge Compression Ignition (HCCI) engine is considered as a new combustion technology
based on auto-ignition with higher thermal efficiency and lower emissions compared with the classic engines.
In the present research, a theoretical model is provided to study the combustion regimes of HCCI engines
fueled with natural gas using detailed chemical kinetics. Simulation results show that the auto-ignition process
can be described using specific definitions of HCCI engines. Also the effects of combustion control parameters
on the combustion initiation and in-cylinder pressure have been studied. The model is able to predict
conditions for a stable controlled combustion applicable for a wide range of operating conditions. The P-θ
curves obtained from the model is compared with the data published in the literature and the comparison
showed a reasonable compatibility in prediction of combustion initiation.
