FTP/SHORT CYCLE CORRELATION TESTING FOR 207 (B) IMPLEMENTATION - CATALYST EQUIPPED VEHICLES. VOLUME I

The objective of the work performed under this contract was to provide test data leading to the identification of which of five existing short-cycle emissions tests is most capable of being 'correlated' with the Federal Test Procedure (FTP) as used for the certification of 1975 model year and later light-duty vehicles. The five short-cycle emission tests are: Clayton key mode - volumetric procedure; Federal three-mode - volumetric procedure; Unloaded test, high speed (2,500 rpm) and idle (derived from 1 and 2) - volumetric procedure; Federal short cycle (9-mode) - CVS procedure; and Composite N.J. ACID/N.Y. short test - CVS procedure. Fifty-eight catalyst equipped experimental vehicles were tested. Design, equipment, and data handling are described.
