  • Combustion process for externally controlled reciprocating piston internal combustion engine operating with hydrogen injection
    Patent number: 4086878
    Abstract: A combustion process for a reciprocating piston internal combustion engine with applied ignition and operating with hydrogen injection as well as an internal combustion engine capable of carrying out the process, in which the air is supplied independently of the hydrogen and an air ring rotating about the cylinder axis is produced which has a density increasing radially outwardly; the injection of the hydrogen into the air ring thereby takes place into the central area of the air ring while ignition takes place within the transition area between the central hydrogen core and the externally rotating air ring.

  • Atomization device for internal combustion engines
    Patent number: 4085717
    Abstract: An atomization system for internal combustion engines for atomizing fuel in an air stream, which includes an atomization space separate from the combustion or working space of the internal combustion engine and traversed at least in part by the combustion air; the electrically conductive fuel supply includes a large number of small capillary tubes projecting into the atomization space from the mounting support thereof while a counter-electrode is provided with a large surface facing the discharge openings of the capillary tubes; additionally, means are provided for guiding the air in such a direction and at such a velocity that the forces exerted on the atomized and electrically charged fuel droplets by the flowing air predominate the electrostatic attracting forces exerted on the droplets by the counter-electrode and thus keep the droplets from the counter-electrode.

  • Method and apparatus for improving exhaust gases of a gas turbine installation
    Patent number: 4085579
    Abstract: A method for operating a gas turbine installation and an apparatus for carrying out the method, particularly for a vehicle gas turbine installation, in which the air is compressed and heated up by utilizing the exhaust gas heat of the gas turbine installation, fuel is combusted under supply of compressed air with an excess of air, the resulting gas is thinned out and cooled off by admixture of compressed heated air, and the produced gas is then permitted to expand for producing an output; a more or less large quantity of non-preheated air is thereby admixed to the preheated primary air prior to the entry into the combustion zone at least within the lower partial load range, preferably as a function of load, in order to control the temperature in the combustion space.
