Delphi Particulate Matter Sensor The Delphi Particulate Matter Sensor is an advanced all-new sensing technology that helps diesel engine manufacturers comply with the latest on-board diagnostic (OBD) standards. In a vehicle equipped with a diesel particulate filter, particulate matter (PM) is created during the combustion process and captured in the vehicle's exhaust system by the diesel particulate filter. Delphi's new Particulate Matter Sensor helps detect leakage in the diesel particulate filter to meet system diagnostic standards. The patented sensor combines fast response and high sensitivity with simplicity of design and self-diagnostic features. It is an affordable sensing technology that offers manufacturers a low cost system integration path. Measures PM in exhaust gas to help detect diesel particulate filter leakage at required threshold levels Delphi Particulate Matter Sensor and Helps manufacturers meet new regulatory requirements in the U.S. PM Sensor Control Module (2015) and Europe (2015+) Spin nut connection to control direction of the sensing element for consistent performance Heater compatible with 12 V or 24 V electrical systems Capable of regeneration across a range of exhaust velocities and temperatures Offered with two shield lengths to match exhaust pipe diameter System includes Delphi-supplied sensor and sensor control module Typical Applications Delphi's Particulate Matter Sensor features variable shield length, which enables a wide variety of heavy duty and light duty diesel transportation applications. Availability The Delphi Particulate Matter Sensor is targeted for start of production in 2014. Contact Delphi for additional information. Performance Advantages In conventional systems, a leak of the diesel particulate filter is detected indirectly by a measurement of pressure drop across the filter. However, stricter emissions regulations will require more accurate diagnosis of the diesel particulate filter to achieve more stringent diagnostic threshold levels. Delphi's new Particulate Matter Sensor features a resistive technique that directly measures PM levels in the exhaust stream and allows the system to determine when emissions levels are exceeded, providing greater accuracy and reliability. www.delphi.com | © Delphi.

Delphi Particulate Matter Sensor Another key feature of the Delphi Particulate Matter Sensor is its unique shield design, which is offered in two shield lengths. It provides improved sensitivity by allowing exhaust gas sampling to occur close to the center of the exhaust pipe, which enables application in a wide variety of heavy duty and light duty diesel engine programs. The Delphi Advantage Delphi has one of the industry's most complete portfolios of sensors and a thorough understanding of systems integration. Delphi offers global manufacturing capabilities for sensors and the benefits of more...
