Particle sensors for onboard diagnostics will soon be required on vehicles to meet upcoming emissions regulations. Many potentially useable sensors available in the marketplace today already target onboard diagnostics and engine control applications. However, more knowledge is needed about how these particle sensors perform in engine exhaust applications under different engine operating conditions where temperature, flow, and particle characteristics are changing. Thus, a consortium is being formed. *Pre-Kickoff Meeting News*The Pre-Kickoff Meeting was held at SwRI in San Antonio on July 26, 2011. Twenty-nine representatives from 21 companies attended the meeting. A series of presentations was given covering particle instruments, sensors, regulations, and consortium structure. SwRI will be sending proposals to the 21 companies that were represented in the pre-kickoff meeting.
NOTE: If your company was
not represented in the Pre-Kickoff Meeting but would like to
receive more information or a proposal from SwRI, please

The schedule of events for the consortium is as follows:
About the ConsortiumCurrent Particle Sensor EvaluationCurrent research and evaluation is inconclusive in determining whether or not a particular particle sensor is sensitive to:
In addition, more knowledge is needed about how well particular particle sensors correlate with soot mass or with total (soot plus volatile) particulate matter (PM) mass since, by definition, total PM mass is a regulated property and soot mass is not a regulated property. To use a particle sensor for onboard diagnostics applications, one needs to understand what it measures and how it responds:
Due diligence in researching this area can be very expensive for particle sensor developers and for engine and vehicle manufacturer stakeholders, because not only does it require special infrastructure and unique capital resources, such efforts also require unique human resources with fundamental knowledge and experience in the area of particle science and engine emissions.
Particle Sensor Performance and Durability ConsortiumThe Department of Emissions Research and Development at Southwest Research Institute (SwRI®) is globally recognized for its efforts in the area of particle emissions research. Our unique capabilities and experiences in engine emissions particle science and technology enable us to offer the best services available to our clients. SwRI plans to make these resources available for evaluating particle sensors by launching the Particle Sensors Performance and Durability (PSPD) Consortium.
Any stakeholder in the consortium (e.g., engine and vehicle manufacturer, or particle sensor manufacturer) can either team together or conduct individual independent particle sensor evaluations on the same engine platform. SwRI's state-of-the-art particle instruments and particle calibration facility will be used to support research efforts during the PSPD Consortium.
Using SwRI's resources, several engine exhaust variables can be controlled, including:
