Two dimensional calculation model of the working process — program «PAS» (Preliminary Analysis of Simulation) — is developed for preliminary planning of three dimensional numerical calculations of the working process in spark ignited engines. The model is based on solution of partial differential equation of energy conservation on base of control volume method with explicit control of the flame front. A new approach for modeling of flame propagation in the internal combustion engine is suggested. The approach represents a combination of control volume method and definition of flame front velocity on base of experimental data (with consideration of phase of flame kernel evolution). In this case it is not necessary to solve the impulse and species transport equations to define a current position the flame front. Thus the model has such advantages as short time of calculation and good predictive ability. Additionally the program can be applied for preliminary validation of three dimensional calculations, then experimental data is not available, and also for obtaining of the heat release curve for implementation in zerodimensional (thermodynamic) models of the working process.
Keywords: control volume method, temperature field.
