The main objective of the present paper is to describe the research work accomplished to develop a combined experimental/numerical calibration method, which has the capability to validate combustion models embedded in an advanced 3-D numerical engine simulation tool. The first part of the paper describes the background for the necessity to use 3-D numerical simulation techniques as well as the basic setup requirements for both the virtual engine model and the real engine experimental support. The paper continues with a description of the method used to derive a 3-D flame front propagation function from direct true-color combustion visualizations. Finally a validation of the suggested method is presented by comparing the obtained results with those produced by an independent thermodynamic computation approach.
