Title:
燃料供給制御装置
Document Type and Number:
Japanese Patent JP6923069
Kind Code:
B2
Abstract:
A fuel supply control device (F, F1) is provided in which a parallel flow path 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 pressure difference before and after 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 below a predetermined threshold value, the fuel supply pump (3) is controlled on the basis of a first fuel measurement amount (Q1), and the fuel supply pump (3) is controlled on the basis of a second fuel measurement amount (Q2).
