AUTOMOBILE EMISSION CONTROL; THE TECHNICAL STATUS AND OUTLOOK AS OF DECEMBER 1974. A REPORT

This report is a summary of the current technical status and outlook in the automobile emission control field. This report has been prepared for the Administrator of the U.S. Environmental Protection Agency (EPA) for two primary reasons: 1. To inform the Administrator of the current status in the emission control technology area. 2. To highlight the important technical issues that may arise during suspension hearings that EPA will hold if automobile manufacturers apply for a one-year suspension of the 1977 HC and CO standards. The report contains a summary and evaluation of the development programs of 25 automobile manufacturers and other organizations involved in the development of automobile emission control technology. The time frame under consideration in this report is from the present until the 1978 model year. Special emphasis is given to the model years 1977 and 1978 since the emission standards for those years are different, and more stringent, than the current, model year 1975, emission standards. Although systems and concepts are currently under development that have a potential for introduction later than the above mentioned time frame they are not given major emphasis in this report. These longer term concepts will be included in next year's and subsequent reports. It should be noted that Congressional changes will result in the relocation of the longer term engine development programs to the Energy Research and Development Agency. Most of the information in this report came from manufacturers' responses to a request from EPA. Most of the responses were received during the month of December 1974, so the information pertains to the period of time immediately prior to December 1974. This specification of the time to which the data relate is important in an area like emission control technology, in which rapid progress is being made. Copies of the responses submitted by the manufacturers are available for public inspection at the EPA Freedom of Information Center at the EPA Headquarters Building, 401 M Street, S.W., Washington, D.C.
