Summary:

This paper describes experiments to determine the effect on exhaust emissions of starting on compressed natural gas (CNG) and then switching to gasoline once the catalyst reaches operating temperature. Carbon monoxide, oxides of nitrogen, and detailed exhaust hydrocarbon speciation data were obtained for dedicated CNG, then unleaded gasoline, and finally CNG start -gasoline run using the Federal Test Procedure at 24°C and at -7°C. The result was a reduction in emissions from the gasoline baseline, especially at -7°C. It was estimated that CNG start - gasoline run resulted in a 71 percent reduction in potential ozone formation per mile
