A device for introducing fuel into the head space of cylinder of non-premixed charge (diesel) engines is disclosed, which distributes fuel in atomized form in a plume, whose fluid dynamic properties are such that the compression heated air in the cylinder head space is entrained into the interior of the plume where it is mixed with and ignites the fuel in the plume interior, to thereby control combustion, particularly by use of a multiplicity of individually controllable devices per cylinder.

A device for introducing atomized fuel into the head space of a cylinder of a non-premixed charge engine for controlled ignition and combustion of the fuel by compression heated air, which comprises: means for generating and intermittently injecting into said head space during a time interval at the end of the compression stroke of said engine, a stream of air at a velocity and volume productive of a plume in said compression heated air, whose fluid dynamic structure causes entrainment and mixing of said compression heated air in the interior of said plume: means for introducing liquid fuel into said stream of air so that it is sheared into fine droplets and carried by said stream of air into said head space; to thereby react with said compression heated air in the interior of said plume and causing said plume to expand to fill a part of the volume of said head space.
