摘要

为优化某二冲程航空活塞汽油机的燃烧特性

研究了火花塞位置、火花塞数量以及火花塞布置方式等对其燃烧的影响。利用Pro-E和AVL Fire软件对该汽油机燃烧室建立了仿真模型

选取缸内压力数据验证了该模型的正确性

对火花塞不同的布置位置以及不同数量的火花塞等方案进行了仿真

对结果进行分析。结果表明：双火花塞布置方案比单火花塞布置方案更有利于组织快速燃烧

促进燃烧放热

缩短燃烧持续期；火花塞非对称布置方案比对称布置方案对火焰的形成及传播扩散更有利。

Abstract

In order to optimize the combustion characteristics of a two-stroke aviation piston gasoline engine

the influence of spark plug position

spark plug number and spark plug arrangement on combustion was studied. The simulation model of the gasoline engine combustion chamber was established by using Pro-E and AVL Fire software. The correctness of the model was verified by the in-cylinder pressure data. The different spark plug positions and different spark plug numbers were simulated and the results were analyzed. The results show that the double spark plug arrangement scheme is more beneficial to the rapid combustion of tissue than the single spark plug arrangement scheme

helping to promote combustion and heat release

shorten the duration of combustion; spark plug asymmetric arrangement scheme is more favorable than the symmetrical arrangement scheme for flame formation and diffusion.
