This report reviews the fuel economy improvement potential of carburetor designs proposed for automotive spark ignition engines. In addition, information is presented pertaining to exhaust emissions and driveability effects, system applicability, and development status. The technical basis for the assessment is derived from data available in the open literature and information acquired through communication with carburetor manufacturers and automobile industry representatives. Carburetor concepts proposed for improved fuel economy generally rely on improved metering accuracy and on the mechanisms of improved atomization, vaporization, and cylinder-to-cylinder distribution, which in turn allow the use of leaner air-fuel mixtures to raise cycle thermodynamic efficiency. The devices evaluated are divided into six categories: sonic, atomizing, vaporizing, constant depression, unconventional fuel metering, and conventional designs.
