PROBLEM TO BE SOLVED: To provide an internal combustion chamber simulation method and an internal combustion chamber simulation system capable of simulating and calculating the spatial distribution state of an air-fuel mixture within a combustion chamber of a direct-injection internal combustion engine with fewer calculation sources in a short time.SOLUTION: It is determined whether a moving position of an air-fuel mixture element Ge collides with a wall surface 13 of a combustion chamber 11 or a wall surface 16 of a cylinder head 15 after preset set time; a moving state of the air-fuel mixture element Ge injected on a fuel injection condition is calculated on the basis of a preset empirical formula if it is determined that the moving position does not collide the wall surface 13 or 16; and a dissolution state of the air-fuel mixture element Ge due to this collision is calculated using collision-time dissolution data calculated by numerical hydrodynamic calculation and formed as a database in advance if it is determined that the moving position collides with the wall surface 13 or 16. |
