摘要

 
为优化丁醇/柴油电控柴油机的综合性能，首先，利用AVL-FIRE建立混合燃料发动机燃烧室模型，采用仿真值与台架试验值对比，对丁醇掺混比和EGR率单因素对发动机综合性能的影响进行仿真研究；然后，采用正交试验设计安排5个重要因素进行多参数优化匹配，将指示功率和NO排放作为评价指标，权重分别设为0.4和0.6.对仿真结果运用模糊数学分析，结果表明：对综合性能影响大小的顺序为：EGR率(a2)、丁醇掺混比(a1)、进气温度(a4)、进气压力(a3)、喷油提前角(a5)；最优参数组合为：a1=10%，a2=12.5%，a3=0.223 MPa，a4=335.15 K，a5=20.6°CA，该组合指示功率53.8 kW较原机的55 kW略低，NO排放质量分数2.2×10-4%较原机的8.5×10-4%降低了74.1%.该优化方法可以在满足动力性的同时，实现有效减少NO排放的目的.

Abstract

In order to optimize the comprehensive performance of butanol / diesel electronically controlled diesel engine, firstly, the combustion chamber model of blended fuel engine was established by AVLFIRE, and the accuracy of the model was verified by comparing the simulation value with the bench test value. The influence of butanol mixing ratio and EGR rates on engine performance was simulated. Then, five important factors were arranged to optimize the multi parameter matching by orthogonal experimental design, and the indicated power and NO emission were taken as evaluation indexes, with weights of 0.4 and 0.6 respectively. Fuzzy mathematics analysis was used to analyze the simulation results, and the results show that the order of influence on comprehensive performance was: EGR rate (a2), butanol mixing ratio (a1), intake temperature (a4),intake pressure (a3), injection advance angle (a5); the optimal parameter combination is: a1=10%,a2= 12.5%,a3= 0.223 MPa, a4= 335.15 K,
a5= 20.6 °CA. The indicated power of the combination is 53.8 kW, which is slightly lower than that of the original 55 kW. The mass fraction of NO emssion 2.2×10-4% is 74.1% lower than that of the original 8.5×10-4%. The optimization method can meet the dynamic performance and at the same time achieve the purpose of effectively reducing NO emissions.

Key words： electronically controlled diesel engine; butanol; performance optimization; fuzzy analysis
