Soot sensors for efficient combustion and low emissions - SootSensII
(2011) In NICE- Abstract
- Nanosized soot particles are a serious health hazard in urban air. Upon inhalation they
can penetrate deep into the lungs and their fat solubility makes possible their
accumulation in other organs such as the brain. For this reason legislation has
continuously reduced the allowable emission levels and raised requirements for reporting
the status of the exhaust system (OBD, on board diagnostics) in diesel powered vehicles.
To meet the California Air Resources Board proposed legislation for diesel particulate
filter, 17.5 mg/mile for light duty vehicles after 2013, will require the development of

To meet the California Air Resources Board proposed legislation for diesel particulate
filter, 17.5 mg/mile for light duty vehicles after 2013, will require the development of
new sensors for monitoring the exhaust and in particular the status of the particulate filter.
The objective in this project was to further optimize the soot sensor based on
thermophoresis, that is a cold sensor surface, for improved sensitivity (patent filed) and to
test transistor based sensor structures. The goal was to perform proof of concept of
thermophoretic soot sensors in order to get sensor manufacturers to pick up the
technology and car manufacturers to implement it. Another goal was to develop an
aerosol based soot generation system, by which soot sensors can be tested and calibrated
in the laboratory before expensive testing in car and truck engines. (Less)
