<p>1,114,610. Regulating LC. engines. SULZER BROS. Ltd. Dec.31, 1965 [Feb. 2, 1965], No.55410/65. Heading F1B. In a method of operating a diesel engine on liquid fuel and/or gas generated by the evaporation of liquefied gas 3 in a container 1 by the absorbtion of ambient heat, the gas is supplied at a rate which depends on the rate at which it is generated and the total fuel requirement at the desired output is made up with liquid fuel. One or more thermally insulated containers 1 e. g. in a ship, supply gas through pipe 5, heat exchanger 6 and regulator 11 to the inlet of a multi-stage centrifugal compressor 12. The gas pressure acts through line 17 on a controller 16 which actuates switches 15 to control electric motor 13 and also actuates the regulator element 11 through a servo-control (not described). Compressor 12 supplies gas through line 18 to the diesel engine inlet valves (not shown) which are operated by an engine-driven telemotor pump 36. A pipeline 21 communicates the gas delivery pressure through an adjustable pressure reducer 23 to a pressure sensitive capsule 24 which acts on the fuel delivery rod 28 of a fuel injection pump 30. A fulcrumed lever 34 is arranged to interconnect the delivery control rods 28 and 35 so that an increase of liquid fuel delivery causes a reduction in gaseous fuel delivery and vice versa. Lever 34 is joined to the output lever of a governor 44 whose setting lever 45 is connected to the engine operating lever 47. Excess pressure in container 1 is relieved to atmosphere through valve 7. Motor 13 may be arranged to be driven at a varying speed in accordance with the amount of gas generated or with the pressure in the delivery line. Regulator 22 may be replaced by an indirect servo system.</p> |
