Document Type and Number:
Japanese Patent JP6668566
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To supply stable fuel by controlling the supply of the fuel so as to cope with a rapid load change of an engine even if the load change of the engine occurs.SOLUTION: A fuel gas supply system 10 for supplying fuel gas to an engine 40 comprises a tank 20 for liquefied gas, a pressurizing mechanism 30 for pressurizing and delivering boil-off gas of the liquefied gas or the liquefied gas as fuel, and a pressurization control device 62 for controlling a delivery rate of the fuel to be delivered by the pressurizing mechanism. The control of the delivery rate to be performed by the pressurization control device includes feedback control for controlling the delivery rate on the basis of a difference between a set pressure established on the basis of a required pressure of the fuel required by the engine and a measured pressure of the fuel after the pressurization, and feedforward control for controlling the delivery rate on the basis of a change in a gas load signal indicating consumption of the fuel gas in the engine.SELECTED DRAWING: Figure 1
