An evaluation was conducted of a two-stroke small displacement engine for which modifications had been developed. The test vehicle used was a 1967 Saab equipped with a manual four-speed transmission. The engine was modified by replacing the stock cylinder head. A hot start 1972 Federal Emission Test Procedure and a cold start 1975 FTP were performed on the vehicle. Bag samples were analyzed for hydrocarbon, carbon monoxide, carbon dioxide, and nitrogen oxides. Steady state cruise emissions were collected in CVS bags at 20, 30, 40, and 50 miles per hour. Results are tabulated. While the system does exhibit very low carbon monoxide and oxides of nitrogen levels, the excessive hydrocarbon levels indicate that a major modification to the system would be necessary to approach 1976 Federal emission standards.
