Evaluation of Applicability of Inspection/Maintenance Tests on a Chevrolet Citation

摘要

This report presents testing results which were gathered to determine the suitability of existing I/M testing scenarios on a Chevrolet Citation with a computer based emission control system. This car had a micro-processor based three-way catalyst control system. After suitable baselines were established, various components were made inoperative in the emission control system. Complete FTP, HFET, New York City Cycles, and I/M tests were run for each vehicle condition. This report presents the measured data taken during the tests.
