- This addresses top level of emission generation and control method. A new quantitative factor of the in-cylinder air-fuel homogeneity named Homogeneity Factor has been developed for the effects of the mixture quality and engine performance. Its characteristics under various conditions are investigated. The results have shown that air-fuel homogeneity is essentially affected by the spatial and temporal fuel distribution. Higher injection pressure, longer dwell time and increased pilot fuel quantities can contribute to better mixing quality, resulting in optimum engine performance with low fuel consumption and soot emissions. The result is part of accredited EU research project targets.
