| 摘 要： | 本文对汽油机准维湍流燃烧模型进行了深入研究。在质量燃烧率方程上,发展了一种基于指数规律变化的燃烧模型,模型认为不同时期形成的涡其燃烧过程是彼此独立的,单个涡的燃烧率变化曲线呈指数形式。

| Abstract: | 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. |
