摘要

采用微分计算方法

在考虑、不考虑燃油中溶解氧逸出这2种极限情况下

建立了燃油箱气相空间冲洗惰化的数学模型

并用实验数据验证了模型的正确性.以无氧逸出模型为基础

定义了物理意义明确的惰化率、气相体积换气次数和总体积换气次数3个参数

用于简捷描述惰化效果及所需要的冲洗气量.研究结果显示:在无氧逸出模型中

气相体积换气次数及惰化终了时气相空间的含氧量与载油量无关

而总体积换气次数随载油量的增加线性减少;在有氧逸出模型中

由于受从燃油中逸出氧气的影响

气相体积换气次数随载油量增加而急剧上升

而总体积换气次数仍与载油量成反比关系;当载油率相同时

有氧逸出模型的换气次数大于无氧逸出模型的换气次数.在进行实际冲洗惰化设计时

可在这2种模型的计算结果之间选择合适的值来估算富氮气体的流量.
