Developed jointly by Corning, the FEV Group, Maguffin Microwave, Detroit Diesel, and Oak Ridge National Laboratory (ORNL) in cooperation with the New York City Department of Sanitation, the Radio Frequency Diesel Particulate Filter Sensor (RF-DPF) is a sensor that uses radio frequencies to measure the amount and distribution of soot and ash in the filters that remove particulate matter from the exhaust of diesel engines. When a vehicle’s particulate filter system is clogged, the sensor signals the engine to burn off the soot, clearing the system. The sensor will enable this process, known as regeneration, to only occur when needed, thereby reducing fuel consumption and enabling longer filter life. The RF-DPF can be used with light- and heavy-duty diesel vehicles. The RF-DPF was a recipient of a 2014 R&D 100 Award, presented by R&D Magazine in recognition of the year’s top technological innovations. When used in diesel vehicles, this technology can save energy, increase fuel economy, and reduce greenhouse gas emissions.
