DUAL-FUEL COORDINATED INJECTION SYSTEM AND SHIP

WIPO Patent Application WO/2024/088008

A1

A dual-fuel coordinated injection system and a ship. The dual-fuel coordinated injection system comprises two sets of fuel supply assemblies and a fuel injector (20), wherein each set of fuel supply assemblies comprises a gas supply pump (10), a control valve (11), a booster pump (12), a fuel tank (15), and a fuel supply pump (16), wherein a gas outlet of the gas supply pump (10) is in communication with a gas inlet of the control valve (11), two working ports of the control valve (11) are in communication with two gas inlets/outlets of the booster pump (12) respectively, a fuel inlet of the fuel supply pump (16) is in communication with the fuel tank (15), a fuel outlet of the fuel supply pump (16) is in communication with a fuel inlet of the booster pump (12), and fuel outlets of the booster pumps (12) in the two sets of fuel supply assemblies are in communication with a fuel inlet of the injector (20), and the injector (20) can inject a fuel into an air cylinder of an engine. The fuel tanks of the two sets of fuel supply assemblies can contain different fuels, thereby improving the flexibility of fuels used by the system, and reducing carbon emissions from the system; and the two sets of fuel supply assemblies share one injector, thereby reducing the cost of the system.
