Abstract |
EPA is in the process of proposing a particulate emission standard for heavy duty diesel vehicles. With this mandated requirement to regulate particulate emissions, EPA must propose a test procedure for the measurement of particulate emissions from diesel engines. A draft recommended practice for measuring particulate emissions from heavy duty diesel engines has already been developed and described in a previous report. In the draft recommended practice, the necessary additions and changes to the current Federal Test Procedure (FTP) were discussed and generally involved (1) the use of a dilution tunnel coupled with a constant mass sampler and (2) the use of filter media to collect the particulate matter over both the cold and hot start portions of the test. The latter of these two requirements (i.e., filter measurements) is of special interest here. The technique of photoacoustic spectroscopy may be an attractive alternative to filter measurements in that it would bring about instantaneous measurement and a short data processing time. This report will investigate present applications of photoacoustic spectroscopy, and discuss the feasibility of this technique as an alternative to filter measurements for certification testing of light-duty disesel vehicles and heavy duty diesel engines. |
