Title:

Fuel injection control device

Document Type and Number:

Japanese Patent JP6217396

Kind Code:

B2

Abstract:

PROBLEM TO BE SOLVED: To improve the accuracy of calculating the fuel injection amount of a fuel injection valve.SOLUTION: A fuel injection control device includes a fuel injection valve 1 having a restricting member 3 for restricting a nozzle needle 21, and control means 8 for controlling the fuel injection amount on the basis of a correlation. The restricting member 3 has full-lift detecting means 31 for detecting that the nozzle needle 21 abuts on the restricting member 3 in such a full-lift state that the nozzle needle 21 is moved to a maximum in a valve opening direction, and then transmitting a detection signal SP to the control means 8. On the basis of an injection period parameter at the time when the full-lift detecting means 31 transmits the detection signal thereto, correcting means corrects the correlation.
