FUEL INJECTION DEVICE FOR DUAL FUEL OF MARINE DIESEL ENGINE

摘要

PURPOSE: A fuel injection device of a ship diesel engine for the mixing combustion of diesel oil and LNG is provided to reduce fuel cost and reduce atmospheric environment pollution by supplying LNG gas, mixed with air, and diesel to a ship diesel engine. CONSTITUTION: A fuel injection device of a ship diesel engine for the mixing combustion of diesel oil and LNG comprises a first fuel supply line(101a), a first electronic valve(104), a vaporizer(102), and a filter(108). The first fuel supply line is expanded from the outlet of a tank(100) storing LNG(Liquified Natural Gas). The first electronic valve is connected to the first fuel supply line and is opened when the engine is driven. The vaporizer vaporizes the liquefied LNG using seawater. The pressure regulator adjusts the LNG gas by concentration and pressure and supplies LNG gas to the combustion chamber of the ship diesel engine. ECU controls the electronic valve, the vaporizer, and the pressure regulator.
