PM Sensors

2012-02-01
Watlow and EmiSense Technologies, LLC are commercializing an improved electronic particulate matter (PM) sensor that has real-time measurement capability and improved sensitivity. To demonstrate the capability of this improved sensor of on board diagnostics (OBD) for failure detection of diesel particle filters (DPF), independent measurements were performed by university of California Riverside (UCR) and by Southwest Research Institute (SwRI) to characterize the engine PM emissions and to compare with the PM sensor response. In situ PM measurements from PM sensors correlate well with real-time gravimetric measurements. In addition, particle size and particle number data are presented and discussed.Due to an improved design update, the sensitivity of the sensor could have been significantly increased.

Monitoring NO2 Production of a Diesel Oxidation Catalyst

2012-01-24
A combination of laboratory reactor measurements and vehicle FTP testing has been combined to demonstrate a method for diagnosing the formation of NO2 from a diesel oxidation catalyst (DOC). Using small cores from a production DOC and simulated diesel exhaust, the laboratory reactor experiments are used to support a model for DOC chemical reaction kinetics. The model we propose shows that the ability to produce NO2 is chemically linked to the ability of the catalyst to oxidize hydrocarbon (HC). For thermally damaged DOCs, loss of the HC oxidation function is simultaneous with loss of the NO2 production function. Since HC oxidation is the source of heat generated in the DOC under regeneration conditions, we conclude that a diagnostic of the DOC exotherm is able to detect the failure of the DOC to produce NO2. Vehicle emissions data from a 6.6 L Duramax HD pick-up with DOC of various levels of thermal degradation is provided to support the diagnostic concept.

Monitoring of Diesel Particulate Filter Using Soot Sensor for EU6 OBD

2012-02-01
Many manufactures are currently working on solutions to fulfill CARB MY 13 requirements for monitoring of diesel particulate filters using a soot sensor. Europe might follow by introducing new OBD limits with EU6 regulation. In this presentation we show results from a study investigating the monitoring capability of a soot sensor in combination with EU6 emission calibration and the OBD matriculate mass limit as proposed in EC 595/2009. A defective diesel particulate filter (DPF) has been detected on roller test bench and under normal driving conditions on public roads. Calibrating a precise soot model is the key factor for the reliability of the particulate filter diagnosis using a soot sensor. Presenter Thomas Czarnecki, Bosch Engineering GmbH
