Title:
FUEL SUPPLY CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/172372
Kind Code:
A1
Abstract:
Provided is a fuel supply control device (F, F1) in which a parallel flow passageway of an orifice (8) and a pressurizing valve (7) is used as a complex pressurizing valve for a fuel supply amount, and which controls a fuel supply pump (3) on the basis of a before-after pressure difference of the complex pressurizing valve that has been detected by a pressure difference meter (9). When the rotational speed (N) of the fuel supply pump (3) is lower than a predetermined threshold value, the fuel supply pump (3) is controlled on the basis of a first fuel measurement quantity (Q1), and the fuel supply pump (3) is controlled on the basis of a second fuel measurement quantity (Q2).
