Nitric oxide emitted from the exhaust of spark-ignition automotive engines has long been recognized as a contributor to air pollution. A mechanical analog for the spark-ignition engine was designed, instrumented, and tested. Product gas concentrations of nitric oxide were monitored in the analog, using an ultraviolet absorption technique. Nitric oxide concentrations were found to be independent of the rate at which product gases were expanded.
