本文阐述了碳平衡燃油消耗量分析法的基本原理;分析了澳大利亚、日本、美国、欧盟等柴油车油耗标准的碳平衡计算模型,其均未考虑柴油车排放颗粒物中的碳元素的存在.由于柴油的分子量大,而且柴油机为直接喷射,混合气不均匀,故部分燃料不能完全燃烧,在高温下分解为以碳为主的颗粒.当柴油车加速或者在车况差时,会产生更多的碳烟,在此基础上对柴油机油耗模型进行修正,对原公式考虑增加碳烟颗粒物的修正项,得出修正模型.分析认为,修正后的模型更合理,可提高计算精度.

This paper describes the basic principle of carbon balance fuel consumption analysis, and analyzes the different carbon balance calculation models in the fuel consumption standards of Australia, Japan, US and EU, which did not consider the element carbon in the particulate matter of emissions from diesel vehicles. As the molecular weight of diesel is large, diesel engine is of direct injection and mixture is inhomogeneous, the combustion of part of fuel can not be complete, and fuel in high temperature decomposes into carbon-based particles. When the diesel vehicles speed up or are in poor condition, they will produce more carbon particle. Based on the original model, the correction term of emissions of particulate matter is considered to be the new term, at last the amendatery model is available. Through the analysis of this formula, the amendatery model comes to be more reasonable and more precise.
