Document Type and Number:
Japanese Patent JP2017002786
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a fuel injection device of an internal combustion engine capable of changing the lift speed of a needle valve, while suppressing addition or change of control for changing the lift speed.SOLUTION: A fuel injection device 100 opens a needle valve 130 to inject fuel from a fuel injection hole 110 by opening a control valve 150, discharging fuel in a control chamber 120 through a leak passage 140 and reducing pressure of fuel in the control chamber 120. The fuel injection device 100 includes a lift speed change mechanism 170 that has a cam 171 rotating with rotation of a crank shaft, and a cam drive valve 172 driven by the cam 171, and that changes resistance in the leak passage 140 according to displacement of the cam drive valve 172.SELECTED DRAWING: Figure 2
