Abstract

It is proposed to reduce pollutant emissions from automobile engines through the use of vaporized alcohol as a fuel and with excess air burn. A fuel vaporization and delivery system for light vehicle engines is discussed. Examination is made of the mechanisms which contribute to the production of pollutants in spark ignition engines and the potential of vaporized alcohol to reduce the effect of several of these mechanisms.
