Diesel particulate filter differential pressure sensor.
Differential pressure sensor delta p for particulate filter applications the pressure sensor described underneath is mainly used to monitor the soot loading of a particulate filter on a diesel engine or gas turbine.
We recommend torque pro.
The ends of the filter plugged in a checkerboard pattern force the soot containing exhaust to flow through the porous filter walls.
The signal of the sensor is not sufficient to determine an optimized timing for regeneration of the dpf.
What does code p244b mean.
The temperature sensor upstream of dpf monitors exhaust temperature during regeneration.
The dpf differential pressure sensor detects the difference between the exhaust pressure upstream and downstream of the diesel particulate filter by means of the exhaust pressure sampling pipes upstream and downstream of the dpf.
