Abstract | Homogeneous charge compression ignition (HCCI) engines use a new mode of combustion where, in principle, there is no spark plug or fuel injector to initiate the combustion. The combustion is self-ignited once the mixture has reached its chemical activation energy. Thus, the combustion is fully controlled by the chemical kinetics mechanism. A zero-dimensional (0-D) single-zone (homogeneous) model was used to study the combustion behaviour, where the model is able to reduce the computing time. A Conditional Moment Closure (CMC) model was then implemented in this 0-D environment to account for the turbulent mixing effects in the combustion chamber. The results show that the use of CMC in a 0-D environment improves on the results from the homogeneous model by eliminating the characteristics of short combustion duration and high peak pressure of the homogeneous model. The model is also in a good agreement with experiment and thus can be used for further analysis. |
