摘要:

基于便携式排放测试系统（PEMS）和油耗监测设备，选取了8台国四排放阶段非道路移动机械（4台挖掘机、4台装载机）进行尾气一氧化碳（CO）、二氧化碳（CO₂）排放量和油耗检测，验证了采用碳平衡法估算油耗的可行性，分析了机械在高功率段的碳排放特征。测试结果表明，油耗与碳排放量显著相关，机械在高功率段实测碳排放因子为640～720 g/（kW·h），是机械全功率段推荐值的11～17倍。采用碳平衡法，可以简便快捷地估算非道路移动机械碳排放量，为制定相关污染防治政策提供技术支撑。

Abstract:

Based on a portable emission measurement system（PEMS） and fuel consumption monitoring equipment， this study selected eight Stage IV emission phase non-road mobile machinery（four excavators and four loaders） to test the carbon monoxide（CO）， carbon dioxide（CO₂） emissions of exhaust， and fuel consumption. The feasibility of estimating fuel consumption using the carbon balance method was verified， and the carbon emission characteristics of the machinery at high power stages were analyzed. The test results show that fuel consumption is significantly correlated with carbon emissions， and the measured carbon emission factor for the machinery in the high power range is 640 to 720 g/（kW·h）， which is 11 to 17 times the recommended value for the entire power range of the machinery. The carbon balance method can be used to conveniently and quickly estimate the carbon emissions of non road mobile machinery， providing technical support for the formulation of related pollution prevention and control policies.
