A novel method for on road emission factor measurements using a plume capture trailer
Morawska, Lidia, Ristovski, Zoran, Johnson, Graham R., Jayaratne, Rohan, & Mengersen, Kerrie L. (2007) A novel method for on road emission factor measurements using a plume capture trailer. Environmental Science and Technology, 41(2), pp. 574-579.
The method outlined provides for emission factor measurements to be made for unmodified vehicles driving under real world conditions at minimal cost. The method consists of a plume capture trailer towed behind a test vehicle. The trailer collects a sample of the naturally diluted plume in a 200 liter conductive bag and this is delivered immediately to a mobile laboratory for subsequent analysis of particulate and gaseous emissions. The method offers low test turnaround times with the potential to complete much larger numbers of emission factor measurements than have been possible using dynamometer testing. Samples can be collected at distances up to three meters from the exhaust pipe allowing investigation of early dilution processes.
Particle size distribution measurements, as well as particle number and mass emission factor measurements, based on naturally diluted plumes are presented. A dilution profile relating the plume dilution ratio to distance from the vehicle tail pipe for a diesel passenger vehicle is also presented. Such profiles are an essential input for new mechanistic roadway air quality models.
