Evaluation of the Applicability of Inspection/Maintenance Tests on a Chevrolet Camaro Z-28

摘要

This report presents test results which were gathered to determine the suitability of existing I/M short tests on a Chevrolet car with a computer based emission control system. This car had a microprocessor based engine control system with a dual bed catalyst. After suitable baselines were established, various components were made inoperative in the emission control system. Complete FTP, HFET, and I/M tests were run for each vehicle condition. Also an on-board system diagnostic check was performed for each configuration after the initial baselines. This report presents the measured data taken during the tests.
