Abstract
It is well known that the turbulent flow field in a spark-ignition engine cylinder plays an important role in determining the combustion characteristics, thermal efficiency and exhaust emissions [1]. EGR(exhaust gas recirculation) reduces NOx emissions, and using lean mixtures improves the thermal efficiency of engine. But these measures cause cycle-to-cycle fluctuations in combustion and deterioration of driveability. In spark-ignition engines, faster burning can raise thermal efficiency and reduce NOx emissions by extending the range of stable engine operation, thus allowing very dilute fuel/air mixtures to be used [2]. It is important to clarify the influence of turbulence and mean fluid motion on combustion and a model is needed to describe these interactions [3]. The entrainment eddy burning model is a reasonable phenomenological model [4–7] for turbulent combustion in the spark-ignition engine. For further development of this combustion model, it is necessary to make clear the turbulence characteristics and the interaction between turbulence and combustion in the engine cylinder.
