摘要

我们考虑了减少内燃机在“冷启动”期间未燃烧的尾气碳氢化合物(HC)排放的问题。利用帕累托优化、冷启动发动机和催化剂模型，分析了催化剂快速“熄火”和减少未燃烧HC之间的权衡。讨论了不同操作条件和催化剂点火特性对优化结果的影响。

Issues in cold start emission control for automotive IC engines

We consider the problem of reducing unburned tailpipe hydrocarbon (HC) emissions for internal combustion engines during the "cold start" period. Using Pareto-optimization, a cold start engine and catalyst model, the trade-offs between rapid catalyst "light-off" and reduction in unburned HC are analyzed. The effects of different operating constraints and catalyst light-off characteristics on the optimization results are also discussed.
