Engine intake fuel fractionator and stratifier

摘要

A single multicomponent internal combustion engine fuel is fractionated by evaporation and mixed with air to form a wide variety of air fuel mixtures within the vaporizer portion. These several kinds of air fuel vapor mixtures differ among themselves as to the kinds of fuel molecules present and as to the ratio of air to fuel vapor. A stratifier valve serves to create a multiregional stratified air fuel mixture at engine intake by drawing differing regions from amongst these many kinds made available within the vaporizer.
