A versatile but simple, reliable, rugged, and compact vehicle exhaust monitoring system has been developed, allowing detection of carbon monoxide carbon dioxide, high and low hydrocarbons, and nitric oxide. The analysis is performed by dispersive absorption spectroscopy with instrumentation designed and fabricatedf or this demanding industrial environment. The operation of the instrumentation is described here, as well as results for both diesel and piston engine emission testing. Testing has been performed on production automobiles, as well as those equipped with thermal reactors or catalytic mufflers, and also both heavy-duty gasoline and diesel engines. The instrumentation has shown very good correlation with other established techniques, and because of its sensitivity, selectivity, ruggedness, and simplicity has been shown to be suitable for vehicle emission analysis.
