Federal test procedure review project: Status report. Technical report

Technical Report ·
OSTI ID:6277628
Section 206 (h) of the Clean Air Act directs the Environmental Protection Agency (EPA) to review and revise as necessary the regulations governing the Federal Test Procedure (FTP) to insure that vehicles are tested under circumstances which reflect the actual current driving conditions under which motor vehicles are used. The Federal Test Procedure is the test procedure used to determine compliance of light-duty motor vehicles with federal emission standards. The status report addresses the progress EPA has made to dare in complying with the Clean Air Act provision and the status of future research efforts. The report discusses four general areas of concern; fuel, temperature, altitude, driver behavior including acceleration. The report also identified several other potential areas of concern relating to driving behavior; speed, cold starts (frequency and driving behavior), trip length, time between trips, and road grade.
