Fuels and Emissions--update and Outlook 1974.
Pres At Nat Combined Farm Construction and Ind Machinery and Powerplant Meetings SAE :15 pages
A change has been observed in the amount and chemical makeup of automotive emissions since the late 1960's. In general, the trend toward decreased levels of the several categories of emissions is well known, but changes in the chemical character of the hydrocarbon component are less well known. The nature of these changes and implications for air pollution effects are discussed. Also, with supplies of motor fuel from petroleum sources in increasing jeopardy, there is growing interest in the character of emissions to be expected in using alternative fuels. The more viable options for alternative fuels are identified, and emission characteristics of these fuels are described.
