Document Type and Number:
Japanese Patent JP6515777
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To appropriately control injection of an injector.SOLUTION: A fuel injection device 100 includes: an injector 100 for injecting fuel; a temperature determination section 50; and a correction section 50. The injector 10 includes a magnetic sensor 40 for detecting a change of a magnetic field caused by movement amount of a valve element and outputting a position signal corresponding to the detected change of the magnetic field. The temperature determination section 50 determines a fuel temperature in the injector 10 on the basis of the position signal at a predetermined position of the valve element 20 and temperature characteristics of the magnetic sensor 40. The correction section 50 corrects a drive signal for driving a driving section 30 on the basis of the fuel temperature determined by the temperature determination section 50.SELECTED DRAWING: Figure 1
