摘要： A method and apparatus for measuring vehicle exhaust emission includes sampling vehicle exhaust and a dilute mixture of vehicle exhaust and ambient air. A first analyzer measures concentrations of gas components of undiluted vehicle exhaust. A second analyzer measures concentration of at least one exhaust gas component present in the dilute mixture gas component. The at least one dilute mixture gas component is a particular exhaust gas component measured by the first analyzer which is also present in ambient air in substantial quantity. Flow rate of the dilute mixture, the concentration of the at least one dilute mixture gas component and undiluted gas concentration are analyzed by a microprocessor to produce mass emissions of the vehicle exhaust gas components.

摘要翻译：用于测量车辆废气排放的方法和装置包括对车辆排气和车辆排气和环境空气的稀释混合物进行采样。第一台分析仪测量未稀释汽车尾气的气体组分浓度。第二分析仪测量存在于稀混合气体组分中的至少一种废气组分的浓度。至少一种稀释混合气体组分是由第一分析仪测量的特定废气组分，其也在大量空气中存在。通过微处理器分析稀释混合物的流速，至少一种稀释混合气体组分的浓度和未稀释的气体浓度，以产生车辆废气组分的质量排放。
