Abstract |
The overall objective of this study is to obtain baseline emissions data from gasoline powered trucks using experimental, 'second generation' type procedures. To acquire the baseline emissions data required, a substantial preparations phase involving further development of chassis dynamometer cycles, the design and construction of a truck version of the PHS Variable Dilution Sampler, and the establishment of correlation with previous program procedures, and different exhaust sampling schemes, are necessary. This interim report reviews and describes these preparations and procedures. The preparations phase for the given classification of trucks includes two major objectives: (1) to establish the relationship between emissions obtained on the simplified SwRI chassis dynamometer and the emissions obtained by the Ethyl Corporation; (2) to conform and establish correlation of exhaust gas sampling by the servoproportional sampling system and variable dilution sampling system. |
