Content
The next generation of diesel engines will require substantial reductions in particulate matter (PM) emissions. In addition to strict regulations, one of the major problems in the development is the lack of sophisticated real-time PM analyzers. The current PM measurement technology consists of a dilution tunnel and filter weighing technique that was developed before the 1980s.(1) Such technology has reached its limit for today's diesel exhaust monitoring requirements in terms of response time and sensitivity. A flame ionization detector (FID), commonly used for measuring hydrocarbons, is proposed as a new analyzer for PM. In the past, spike signals observed from the FID when measuring diesel exhaust have been considered noise and a lot effort has been spent to reduce such interference from the slower FID signal. However, given a fast response time FID, these spike signals could be used to represent PM concentration in the sample. The present paper investigates the sensitivity of the FID to hydrocarbon- free soot and discusses the correlation with the filter measurement method. A new technique to measure PM from diesel exhaust using a FID has been demonstrated.
