Title:
FUEL SUPPLY SYSTEM FOR LARGE TWO-STROKE COMPRESSION-IGNITION HIGH-PRESSURE GAS INJECTION INTERNAL COMBUSTION ENGINE
Document Type and Number:
Japanese Patent JP2018162790
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a fuel supply system for supplying high-pressure gas to a large two-stroke compression-ignition internal combustion engine.SOLUTION: There is provided a fuel injection system for injecting supplied high-pressure gas to a combustion chamber. A fuel supply system comprises a feed pipe 9 that connects a liquefied gas storage tank 8 to a high-pressure pump 40 for transferring liquefied gas to the high-pressure pump 40, a transfer pipe 50 that connects the high-pressure pump 40 to a high-pressure vaporizer 14, and a supply pipe 18 that connects the high-pressure vaporizer 14 to the fuel injection system for transferring high-pressure vaporized gas to the fuel injection system. The high-pressure pump 40 comprises two or more pump units 41, 42, 43. Each pump unit 41, 42, 43 comprises a pump piston 62 slidably disposed in a pump cylinder 61, and a hydraulic drive piston 46 slidably disposed in a drive cylinder 45 with the drive piston 46 for driving the pump piston 62.SELECTED DRAWING: Figure 2
