ABSTRACT:
The devices of this invention, when used in combination with internal combustion engines of spark ignition type and/or compression ignition type, can create a multiregional stratification of the intake air-fuel mixture. By use of multiregional stratification at intake various beneficial objects can be achieved including the following: reduction of engine exhaust emissions of undesireable oxides of nitrogen, improvement of engine efficiency, reduction of engine noise, reduction of engine exhaust smoke, reduction of engine cost and others. The multiregional stratified air-fuel mixture is created by a stratifier valve which selects differing kinds of air-fuel mixtures in sequence from several different mixture creating channels. The resulting multiregional stratified mixture passes from the stratifier valve to the engine intake. Within the engine cylinder this subsequently compressed multiregional stratified mixture may be spark ignited, or compression ignited, or ignited by both spark and compression means.
