Abstract – This article describes different regimes for premixed turbulent combustion in gasoline internal combustion engines and the
way they enhance the burning speed of a turbulent flame comparing with a laminar combustion. For this reason, we classify different regimes and summarize them in a single diagram called Borghi plot where it is possible to distinguish them and separately analyze depending on the characteristics of the turbulence. Finally, we can determine the effect of each regime to the turbulent burning speed
of a premixed flame.
