STUDY OF EXHAUST EMISSIONS FROM 1966 THROUGH 1976 MODEL-YEAR LIGHT-DUTY VEHICLES IN DENVER, CHICAGO, HOUSTON AND PHOENIX

Emission tests were performed on a sample of light-duty vehicles operating in the Chicago, Houston, Phoenix and Denver metropolitan areas. These tests were performed for the determination of light-duty vehicle emission factors. All vehicles were tested in the as-received condition by the Federal Test Procedure. Other tests included the Highway Fuel Economy Test, Modal Emission Tests, the Federal Short Cycle Test, a composite of the New Jersey ACID Test and the New York Short Test, the Clayton Keymode Test, the Two Speed Idle Test and the Federal Three Mode Test. A Revised Federal Three Mode Test and the Sulfate Emission Test were also performed. The Phoenix sample included twenty diesel-powered vehicles which were tested by the diesel version of the Federal Test Procedure, the Highway Fuel Economy Test and Modal Emission Tests. Evaporative Emission Tests by the SHED procedure were also conducted on twenty vehicles in Denver. (Portions of this document are not fully legible)
