| ABSTRACT |
|
The Deterioration Factor (DF) for a single pollutant within an engine family is computed as the ratio of two points on a linear regression line describing durability vehicle test results as a function of accumulated mileage. It is inteded to represent the factor by which emissions will increase during the 'useful life" of a vehicle in the engine family. Here are discribed procedures for computing the DF and how consideration of the DF is included in the development for the motor vehicle emission certification process. This paper is aimed to develop the distribution of the DF for three pollutant and to estimate the parameter values for the distribution of the DF. |
