Abstract |
The report concerns a contract to determine what emission control techniques are feasible for retrofit to used cars, considering emission reduction effectiveness, costs, effect on vehicle performance, and the facilities and labor skills required for retrofit device installation and eventual maintenance and inspection. This report documents the results obtained, pertinent data upon which the results are based, the techniques of test and analysis, and the recommendations for future programs to implement the results. Volume III documents the relative effectiveness and costs of retrofit methods, the techniques of analysis d the assumptions and rationale upon which the analysis was based. |
