| 摘 要： | 为获得工程机械的实际排放因子，利用车载排放测试系统（PEMS）对45辆典型工程机械进行实际工况排放测试. 测试工况包括怠速、行走和作业工况. 结果显示:行走和作业工况下排放速率波动明显，较大的排放峰值主要分布在作业工况下. 怠速工况下CO和HC排放因子相对较高，而作业工况下基于油耗的NOx和PM排放因子高于怠速和行走工况. 推土机CO、HC和PM在3种工况下基于油耗的排放因子明显高于其他机械. 比较国1标准机械与国2标准机械发现，国2标准机械CO，HC，NOx和PM在各个测试工况下的排放因子均有不同程度的降低.

| Abstract: | In this study, emission tests were performed on 45 typical construction equipment by using portable emission measurement system (PEMS) to obtain their emission factors. Test cycles include idling, moving and working. Result showed that variations occurred on moving and working cycles, while most of peaks happen on working cycle. Emission characteristics based on fuel consumption were analyzed and emission inventory were calculated according to the measurement data and fuel consumption survey data. The results show that fuel-based emission factors of CO and HC are higher on idling operating mode, while NOx and PM are higher on working mode. Fuel-based emission factors of CO, HC, and PM are higher from bulldozer than those from other equipment. Compared with stage Ⅰ equipment, the fuel-based emission factors of stage Ⅱ equipment lower to a certain extent. |
