Washington, L H

A comprehensive study was conducted of automobile exhaust emissions and the effects of restorative maintenance and selective engine parameter maladjustment on these emissions. This was a study of 100, 1975 and 1976 model year consumer owned vehicles from the Washington, D.C. area and was an addition to a total surveillance program which had been conducted in seven major cities (Denver, Washington, D.C., Los Angeles, Houston, Phoenix, Chicago and St. Louis) in order to determine the impact of automobile emissions on air quality. This additional study was not made in all seven of the cities involved in the original study. Specifically, vehicles from the Washington, D.C. area were tested for fuel economy and the content of total hydrocarbons, carbon monoxide, carbon dioxide and nitrogen oxides in their exhaust emissions using the 1975 Federal Test Procedure, the Highway Fuel Economy Test, the Federal Short Cycle, the New York-New Jersey Acid Test, the Clayton Key Mode Test, the Two Speed Idle Test, and the Federal Three Mode Test.
