The original E-75 Diesel Speciation Database was reformatted to perform the E-75-2 data analysis, and fields not required for the analysis were eliminated. As described in the E-75-2 report, this second database contains some added records, and some records from the original database have been screened out. Sufficient identifying information is included in the E-75-2 database to map it back to the original data record in the E-75 database. It is provided here for your convenience.

Compilation of Diesel Emissions Speciation Data

The E-75 database was used as the starting point for the E-75-2 project. In the course of the E-75- 2 project, some errors were found in the E-75 database and corrected in the E-75-2 database. However, the E-75 database contains additional data fields that were not needed for the E-75-2 analysis and so are not included in the E-75-2 database. Therefore, the original E-75 database is still useful in providing these additional data fields, but the user should first verify that the emissions data is correct by finding the corresponding emissions data record in the E-75-2 database.

The Final Report for AVFL-13 has been revised. The original report contains an error of scale in the hydrocarbon emissions results, which are high by a factor of three. The links below provide details of the revision. There are two letters from AVL which explain the source of the error and describe the revisions to the final report. An email letter from CRC Consultant Dr. Bill Leppard is also included, to put the impact of this error in context — no conclusions of the study are altered by this update.
