摘要

将277台国六重型车用柴油机分别进行WHSC循环和WHTC循环试验，分析稳态工况和瞬态工况下CO₂排放水平分布情况，以及发动机排量和发动机功率对CO₂排放水平的影响。基于N₂O的生成机理，分析46台国六重型车用柴油机的WHSC循环和WHTC循环试验结果，对比EGR路线和发动机排量对N₂O排放水平的影响。根据3台国六重型车用柴油机在不同海拔下的CO₂与N₂O排放浓度、循环比排放量的差异，分析了高海拔对温室气体排放的影响。研究结果表明：试验样本整体排放水平可作为CO₂排放限值和N₂O排放限值拟定基准；发动机排量对CO₂和N₂O限值划分与实际应用有较大影响；CO₂排放监管可忽略高海拔因素，而N₂O排放监管则需考虑其影响。

Abstract

The WHSC cycle and WHTC cycle tests were carried out on 277 China Ⅵ heavy-duty diesel engines to analyze the distribution of CO₂ emission level under steady-state and transient conditions, as well as the effects of engine displacement and power on CO₂ emission level. Based on the formation mechanism of N₂O, the WHSC and WHTC cycle test results of 46 China Ⅵ heavy-duty diesel engines were analyzed, and the effects of EGR technology route and engine displacement on N₂O emission level were compared. According to the differences of CO₂and N₂O emission concentrations and cycle specific emissions between different altitudes from 3 China Ⅵ heavy-duty diesel engines, the effect of high altitude on greenhouse gas emission was analyzed. The research results show that the total emission level of test samples can be used as a benchmark for the CO₂ and N₂O emission limit. The engine displacement has a great influence on the division and practical application of the two limits. The high altitude factor can be ignored for CO₂ emission regulation, while its impact should be considered for N₂O emission regulation.
