  • Ducted fuel injection
    Patent number: 10161626
    Abstract: Various technologies presented herein relate to enhancing mixing inside a combustion chamber to form one or more locally premixed mixtures comprising fuel and charge-gas to enable minimal, or no, generation of soot and/or other undesired emissions during ignition and subsequent combustion of the locally premixed mixtures. To enable sufficient mixing of the fuel and charge-gas, a jet of fuel can be directed to pass through a bore of a duct causing charge-gas to be drawn into the bore creating turbulence to mix the fuel and the drawn charge-gas. The duct can be located proximate to an opening in a tip of a fuel injector. The various technologies presented herein can be utilized in a number of combustion systems, such as compression-ignition (CI) reciprocating engines, spark-ignition (SI) reciprocating engines, gas-turbine (GT) engines, burners and boilers, wellhead/refinery flaring, etc.

  • Press machine and method for controlling slide of press machine
    Patent number: 10160175
    Abstract: There is provided a press machine which can apply a large compression force to a mold as well as impart smooth vibration only in a rectilinear advancing direction to the mold, and thereby can improve the press-formability. A main slide and a sub-slide constitute a slide and at the same time a cylinder-piston mechanism. During press-forming, a compression force is transmitted to the sub-slide (an upper mold) through hydraulic pressure applied interlockingly with driving of the main slide, and the sub-slide is vibrated with the hydraulic pressure being periodically changed. Favorable press-forming can be performed even under relatively difficult press-forming conditions, by controlling the vibration such that a vibration frequency of the sub-slide (the upper mold) becomes 9 Hz or higher but 33.3 Hz or lower and a vibration amplitude of the sub-slide becomes 0.05 mm or larger but 0.5 mm or smaller.

  • Compact Multi-Function LED Lighthead
    Publication number: 20180363876
    Abstract: A multifunction lighthead for mounting to a vehicle includes several groups of LEDs arranged to provide distinct light emission patterns. Each group of LEDs and associated optics are selected and positioned to produce light emission patterns needed to meet lighting standards applicable to the vehicle. Such standards may require wide angle light emission, which is enhanced by supporting groups of LEDs that project away from the vehicle body, enhancing visibility of the lighthead from directions close to a plane defined by the body panel. The projecting support for the LEDs and optics for a wide angle light emission pattern may be employed to support LEDs arranged for ground illumination. Other groups of LEDs in the same lighthead may be arranged with optics to provide area illumination in support of arrest, search, triage or other emergency functions.
