  • Pulsed jet combustion generator for non-premixed charge engines
    Patent number: 4974571
    Abstract: 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.
    Type: Grant
    Filed: February 24, 1989
    Date of Patent: December 4, 1990
    Assignee: Regents of the University of California
    Inventors: A. K. Oppenheim, H. E. Stewart
  • Pulsed jet combustion generator for premixed charge engines
    Patent number: 4926818
    Abstract: A method and device for generating pulsed jets which will form plumes comprising eddie structures, which will entrain a fuel/air mixture from the head space of an internal combustion engine, and mixing this fuel/air mixture with a pre-ignited fuel/air mixture of the plumes thereby causing combustion of the reactants to occur within the interior of the eddie structures.
