Project Status: complete

Title: Quantification of evaporative running losses from light duty gasoline powered trucks

Principal Investigator / Author(s): McClement, Dennis

Contractor: Automotive Testing Laboratories, Inc.

Contract Number: A992-224


Research Program Area: Emissions Monitoring & Control

Topic Areas: Mobile Sources & Fuels


Abstract:

The purpose of this effort was to collect Running Loss Emission Data on a representative cross section of in-use, light-duty trucks to support the development of California specific emission factors. Eighteen randomly procured vehicles were tested. A total of 76 sequences were performed. Tests were performed using fuels at 9.0 psi RVP, ambient temperatures of 45, 95 and 105įF, and the LA-4 and NYCC driving sequences. Modified SHED sequences were performed on six vehicles. Results were consistent with previous studies.
