Soot sensors are required for on-board diagnostics (OBD) of automotive diesel particulate filters (DPF) to detect filter failures. Widely used this purpose conductometric sensors, measuring an electrical current or resistance between two electrodes. particles deposit on the electrodes, which leads increase in decrease resistance. If installed upstream a DPF, “engine-out” soot emissions can also be determined directly by sensors. Sensors were characterized engine real exhausts under varying...
Understanding the variation of soot deposit properties in diesel particulate filters is necessary for their real-life modeling and onboard control. In this study, effect exhaust mass flow rate particle agglomerate size on layer permeability density was investigated experimentally analyzed using a well-validated model. A bare coated filter were loaded at five different engine operating points, specially selected to explore these effects heavily used part map. Particle emissions characterized...
