Exhaust Particle Sensor for OBD Application

Apr 12, 2011· The sensor was found to be sensitive enough to clearly detect a defected from a well-operating particle filter even at levels as low as 6 mg km-1. This study demonstrates that a soot sensor based on the escaping current technique has the potential to be used for OBD and DPF control on forthcoming light-duty and heavy-duty diesel vehicles.

Soot (PM) Sensors

Hence, the only remaining electrical charge in the flow is that left on the soot particles. Particle concentration is measured when a Faraday cup detects the net, total charge left on the charged particles as they exit the sensor. Figure 14. Schematic of an ionizing soot sensor (Pegasor) The sensor uses ionized air to charge soot particles.

PM Measurement: In-Situ Methods

Pegasor Particle Sensor. Another diffusion charging based system is the Pegasor Particle Sensor (PPS) [3427]. This sensor contains no sizing section, the calibration in number concentration therefore depends on the particle size distribution. To overcome this, it was suggested to use two sensors with different tuning [3428]. The ratio of the ...
