Southwest Research Institute Launches Particle Sensor Performance and Durability Consortium

SAN ANTONIO--(BUSINESS WIRE)--Southwest Research Institute (SwRI) will launch a cooperative research consortium to investigate the performance and durability of particle sensors designed for onboard diagnostics and diesel engine emissions control.

Sensors that trigger engine malfunction illumination light (MIL) or a fault code when particle emissions exceed a certain threshold downstream of an exhaust diesel particle filter (DPF) will soon be required to meet California Air Resources Board and U.S. Environmental Protection Agency onboard diagnostics regulations. Particle sensors assess how well particle filters keep particulate matter from being emitted to the atmosphere, in compliance with emissions regulations.
