Analysis of the Costs of Particulate Trap-Oxidizer Systems for Heavy-Duty Diesel Vehicles

摘要

An understanding of the basis for this difference in the cost estimates between the Environmental Protection Agency (EPA) and the manufactuers is the stimulus for this paper. The difference exists even though EPA conducted a reevaluation of its cost estimates for the regulatory impact analysis. This paper reports the results of a study in which EPA's, the manufacturers', and other particulate trap-oxidizer system cost estimates were analyzed and the reasons for the differences among the cost estimates documented. Because many papers and reports are available that discuss the viability (effectiveness, impact on engine performance) of specific systems in detail, this does not discuss these concerns except as they affect the cost estimates for trap-oxidizer systems.
