Abstract
Sixteen gas analyzers are used to measure emissions into and out of the catalytic converters while conducting Environmental Protection Agency vehicle test procedures. A computer system controls the analyzer consoles, logs test data, and provides test results quickly. The computer logs data during testing, then on command transmits it to the GM Research Laboratories (GMR) Data Center. Data reduction is done at the GMR Data Center because it has a large computer to do the calculations and programmers to maintain the reduction programs. The test summary can be transmitted back to the test site.
The system was tested extensively to verify accuracy of results. Gas analyzers were calibrated, data logging and handling were checked, and the data reduction programs were scrutinized. The system has given consistent results during its operation.
