The volume summarizes the general objectives, approach and results of the study. The economic effectiveness model is designed to evaluate two general vehicle inspection and maintenance strategies: (1) direct inspection of engine and control device adjustments and their maintenance using conventional or more sophisticated garage equipment and (2) measurement of exhaust emissions at various engine loads to diagnose engine maladjustments followed by their subsequent maintenance. The model provides considerable latitude to investigate particular procedures within the framework of these two general strategies.
