As emissions regulations continue to evolve globally, OEMs face increasing pressure to improve particulate matter monitoring performance, support more stringent OBD requirements and detect emissions system issues quickly and accurately. Reduced particulate matter monitoring thresholds, including those established by the California Air Resources Board (CARB), are increasing focus on monitoring sensitivity, response time and diagnostic performance. Current sensing technologies can encounter challenges meeting these demands, particularly as monitoring thresholds become more stringent.
Sensata's ePM sensor is designed to address these challenges through high-accuracy electrostatic sensing, continuous monitoring capability and a tamper-resistant design. Positioned downstream of the diesel particulate filter (DPF), the sensor provides continuous visibility into particulate matter emissions and can identify DPF malfunction when particulate matter concentrations exceed monitoring thresholds. The combination of sensitivity, response time and continuous measurement enables stronger diagnostic confidence as emissions monitoring requirements become increasingly demanding.
"As emissions monitoring requirements become more stringent, OEMs need sensing solutions that provide greater sensitivity, faster response and enhanced diagnostic confidence," said Markus Schwabe, Executive Vice President and President, Automotive, Sensata Technologies. "The ePM sensor expands Sensata's emissions monitoring capabilities with a solution designed to enable customers to address evolving regulatory requirements, strengthen emissions system diagnostics and prepare for future diesel platform demands."
Key features and benefits include:
- High-accuracy electrostatic sensing: Supports reliable particulate matter monitoring and detection of particulate matter concentrations as low as 10 mg/mi, enabling OEMs to address increasingly stringent emissions monitoring requirements.
- Real-time continuous monitoring: Provides faster response and continuous visibility into particulate matter emissions, equipping OEMs to support evolving onboard diagnostics (OBD) requirements and emissions system diagnostics.
- Tamper-resistant design: Supports emissions monitoring strategies and regulatory requirements while providing greater confidence in long-term system performance.
Supporting light-, medium- and heavy-duty vehicle applications, the ePM sensor expands Sensata’s portfolio of sensing solutions designed to enable OEMs to address evolving emissions requirements. The introduction of the ePM Sensor reinforces Sensata's longstanding commitment to providing technologies that improve emissions performance, support compliance and advance cleaner and more efficient internal combustion engine vehicles.
