ABSTRACT:
An air fuel vapor stratifier apparatus is described, for use with piston internal combustion engines, to create stratified air fuel vapor mixtures within the engine combustion chamber. A fuel rich air fuel vapor mixture is created within a separate chamber, and then displaced into the engine combustion chamber, where it mixes with air contained therein. The consequently leaner air fuel vapor mixture is spark ignited following mixing, and burning takes place. Very lean overall air fuel ratios can be used since a stratified mixture is created. Hence intake air throttling is unnecessary and thus engine efficiency is improved. The absence of liquid fuel during burning in the engine combustion chamber, largely prevents the formation of soot, and thus reduces undesirable exhaust smoke.
