Evaluation of On-Board Real-Time Particulate Emissions Measurement(ST10022-1)

Southern Research Institute


Due to the increased interest in particulate matter (PM), the need for evaluating PM emissions in real time and in real-world, in-use applications has been recognized. Technology developers have responded with continuous development of novel state-of-the-art PM measurement technologies over the past several years. Still, as with any new technology, there remain questions about the performance of these new technologies.

Project Description

Needs include: form an advisory group of stakeholders including regulatory agencies, national research organizations, instrumentation vendors, and engine manufacturers. Develop a test plan using an engine or heavy duty diesel chassis dynamometer to assess the performance of selected PM measurement technologies on a single engine. Conduct laboratory dynamometer tests to obtain statistically valid results with and without a diesel particle filter. A minimum of three acceptable runs are anticipated per test. Tests will include steady load (a minimum of five load conditions) and transient load runs following accepted test protocols. Conduct in-use tests with heavy-duty diesel vehicle, to be determined, if real-time PM instruments produce results of acceptable precision and accuracy compared to federal reference methods.


This project will allow for the identification of feasible technologies for real-time in-use PM measurement, which will in turn allow users in NYS to obtain a larger set of emissions data from mobile sources in a more cost-effective and accurate manner than currently available methods and estimates. NYS will then be able to evaluate various PM control technologies/strategies in real applications for potential recommendation under existing and future regulations; focus development of technology and more effectively use funds; and make future control programs more efficient, effective, and economical.
