Abstract
General Environments Corporation (GEC) of Springfield, Virginia was selected to participate in the FY73 Emission Factors Program by the Environmental Protection Agency (EPA). One hundred eighty privately owned light-duty vehicles from the metropolitan Newark, New Jersey area were tested for exhaust emission levels of total hydrocarbons, carbon monoxide, carbon dioxide, oxides of nitrogen, light hydrocarbons, and aliphatic aldehydes according to the 1975 Federal Test Procedure. All vehicles were also tested for highway fuel economy and vehicles from 1972 through 1974 were tested for modal emissions. The test results were used to compute emission factors based on both the 1972 and 1975 Federal Test Procedures. Portions of the document are not fully legible.

Contents Notes
A laboratory emissions study was conducted on a sample of 1967-1974 model-year vehicles operating in Denver, Houston and Detroit. Emissions from five-hundred and forty vehicles, one hundred and eighty from each city, were investigated. Sound level tests were also performed on eighty-five vehicles from the San Antonio area. Exhaust emission tests were performed on each vehicle in the as-received condition using the 1975 Federal Test Procedure. Evaporative emission tests were performed on twenty 1973 model-year vehicles in the Denver area using the canister collection procedure of the Federal Register and the SHED testing techniques of SAE J 171. A variety of additional exhaust emission tests were also performed. Modal emissions data were developed from seventy-five of the 1972, 1973 and 1974 model-year vehicles in each site using Surveillance Driving Sequence and steady state testing procedures. Emissions from air conditioned vehicles were investigated in Houston and Dtroit using a sequence of four modified FTP hot start tests. Emissions from loaded vehicles and vehicles towing trailers were also investigated using Surveillance Driving Sequence and steady state testing procedures. Sound level tests were performed at the wide open throttle test condition in accordance with the SAE J986a procedure and at the five operating conditions of the EPA Use Cycle Modes. Additional tests were conducted for use in sound level contour development.
