Evaluation of restorative maintenance on 1975 and 1976 light-duty vehicles in Detroit, Michigan
Technical Report
·
OSTI ID:6265426
A study of exhaust emissions from 100 consumer-owned 1975-1976 model-year light-duty vehicles equally represented by the big three manufacturers was performed by Olson Laboratories, Inc., in Livonia, Michigan to determine the relationship of emissions to the maintenance condition of the vehicles. All vehicles were tested using the 1975 Federal Test Procedure. Additional emission tests were conducted including Highway Fuel Economy Tests and several short-cycle tests. Each vehicle was tested initially in the as-received condition. Various stages of restorative maintenance and retesting were then performed in an attempt to bring vehicles which failed the emission standards into compliance. Selected vehicles were also subjected to a series of specified maladjustments or disablements in order to evaluate the individual and combined effects of these conditions on emissions and fuel economy.
