N2 - The IC engine is investigated numerically by Cartesian mesh system. The Building Cube Method is adopted to generate the mesh partition for complicated engine geometry and parallel computation. The fully compressible flow solver by Roe scheme and 5th order MUSCL is used to calculate the flow field with high pressure and temperature differences. The species transport equations are solved with 11 species of combustion in this framework. The chemical reaction of combustion is conducted by equilibrium solver of Cantera module, which is used for evaluate the equilibrium state of the reacting flow, and merged with the flow solver and G-equation flame front treatment. In order to simulate the engine motion, the geometry and engine moving piston is calculated by Immersed Boundary Method. The flow field of velocity, density and flame front due to the combustion and engine motion is shown in the results. The validation is done by the Rapid Compression Machine simulation with the comparison of experimental data. The flame front shapes and flame propagation speed of this framework are well consistent with the experimental results.
