Title:
燃料噴射制御装置、燃料噴射システム及び燃料噴射弁
Document Type and Number:
Japanese Patent JP6481597
Kind Code:
B2
Abstract:
A fuel injection system (100) includes a fuel injection valve (10), an ECU (11), a pressure accumulating vessel (12) and a fuel pump (13). The fuel injection valve (10) and the pressure accumulating vessel (12) are connected to one another by means of a supply passage (71), and high-pressure fuel is supplied from the pressure accumulating vessel (12) to the fuel injection valve (10) via the supply passage (71). The fuel injection valve (10) includes injection holes (21) for injecting fuel, and a high-pressure passage (22) for guiding high-pressure fuel to the injection holes (21). The high-pressure passage (22) connects the injection holes (21) to the supply passage (71), and a high-pressure orifice (72) which has a variable degree of restriction to allow the fuel flow rate to be adjusted is provided in the high-pressure passage (22). The degree of restriction of the high-pressure orifice (72) is set on the basis of the amount of fuel to be injected from the fuel injection valve (10) and the injection interval.
