Improvement of the Mass Burning Rate in a Quasi-dimensional Turbulent Combustion Model of SI Engines

In this paper, a quasi-dimensional turbulent combustion model for SI engines is thoroughly studied. On burning rate equation, a new formula is put forward, with mechanism difference from the traditional models. In the traditional models, all different eddies formed in different periods are burnt in identical rate; while in the new formulae, every eddy has its own life and is burnt in different rate. They are separated from each other and are consumed in exponential law.
