  • Low emission dual fuel valve structure
    Patent number: 5329906
    Abstract: This invention relates to a dual fuel engine cylinder with primary interest focused upon an injector valve for an alternate fuel in which the body of the valve is disposed into said cylinder through the head thereof and may be removed therefrom as for servicing without disturbing the remaining operation of the cylinder.
    Type: Grant
    Filed: August 16, 1993
    Date of Patent: July 19, 1994
    Assignee: Energy Conversions, Inc.
    Inventors: Scott P. Jensen, Mitchel J. Gillispie, Robert A. McLean
  • Low emission cylinder cut-out idle system
    Patent number: 5195485
    Abstract: The invention is directed to reducing unburned hydrocarbons during engine idling. During idling, one cylinder bank of an engine is alternately deactived by fuel cut-off structure with another cylinder bank. Therefore, one bank works twice as hard and consequently produces much lower emissions. A timer alternates between the cylinder banks anywhere from fifteen seconds to four minutes.

  • Dual fuel injection structure
    Patent number: 5136986
    Abstract: A fuel injection structure for dual fueled combustion engines having access to the combustion chamber of a cylinder to automatically supplement a liquid fuel with a gaseous fuel, the structure being adapted to supply the gaseous fuel by a programmed electronic control circuit which regulates the operation of fuel injection to be in accord with certain sensed engine operation parameters to determine from said parameters a desired gaseous fuel flow rate and a signal responsive to said parameters actuating a valve to control said flow.

  • Gaseous fuel injector valve
    Patent number: 4865001
    Abstract: A gaseous fuel injector valve for diesel engines having access to the combustion chamber of a cylinder to supplement diesel fuel with natural gas, the valve being adapted to supply gaseous fuel by a programmed electronic control circuit which regulates the valve operation to be in accord with certain sensed engine operation parameters and in timed sequence with the crankshaft position for the optimum time to introduce gaseous fuel.
