In this paper, the performance of a natural gas HCCI engine is studied through a thermodynamic model including detailed chemical kinetics. Then the influence of using formaldehyde as an additive on the engine characteristics has been investigated. Results show that it is possible to change engine working limits using this additive. Furthermore, there is an optimum additive content for each operating condition which leads to higher output work and power. It is also shown that the air/fuel mixture will ignite earlier using this additive so it is conceivable to reduce inlet mixture temperature resulting in better performance due to higher volumetric efficiency.

Recently, we developed a numerical approach for the simulation of detonation waves on fully unstructured grids and applied it to the numerical study of the mechanisms of detonation initiation in multifocusing systems. Current work is devoted to further development of our numerical approach, namely, parallelization of the numerical scheme and introduction of more comprehensive detailed chemical kinetics scheme.
