| Abstract |
A 1970 Plymouth Duster, equipped with a 225 cu. in. six cylinder engine and automatic transmission was modified, with changes to the intake manifold, lean main jets in the carburetor and revised camshaft. The intake modification consisted of truncated cone inserts placed in each inlet port. The following standard emission tests were run: (1) standard 1970 Federal test procedure for exhaust emissions (FTP); (2) closed, constant volume sampling technique using 9 repeats of the 7-mode Federal emissions test cycle (CVS); (3) closed constant volume sampling technique using the LA4-S3 driving schedule as specified for 1972 and later. Performance tests were also conducted, consisting of wide open accelerations from 0-60 mph, 20-50 mph and 40-80 mph. The results indicate that the Roberts device: (1) caused no significant change in unburned hydrocarbons or carbon monoxide; (2) caused some (27%) reduction in oxides of nitrogen and (3) had a small detrimental effect on performance at high loads. |
