INTRODUCTION AND SUMMARY

The experiments performed to develop, characterize, and rank vehicle inspection and maintenance procedures are described in this volume. The data from these experiments are the fundamental building blocks for the economic-effectiveness model of Volume II.

The experimental data were developed from the following sequence of investigations as indicated in the flow diagram, Figure 1-1.

An engine parameter field survey to characterize the general maintenance state of vehicle emission control systems

A screening experiment to select the most frequent and extensive malfunctioned engine parameters

A definitive experiment to select and evaluate the most effective parameters to maintain in an inspection as determined by combining the data from the previous two experiments

These experiments were designed to yield a consistent set of data to support the emissions models. Inspection procedures using both direct engine parameter and emission diagnosis were developed with these data. The approach is represented mathematically by the following equation relating a change in emissions (composite or diagnostic) to the frequency, extent, and sensitivity of the parameter malfunction
