Abstract
A fuel injection device includes: a current control section which turns off a current which is applied by a current output section such that a timing at which fuel injection of a fuel injection section is ended becomes a timing coinciding with a timing at which fuel injection is ended in a case where a current is turned off from a predetermined current amount at which continuation of the fuel injection of the fuel injection section becomes possible, in a case where a fuel injection ending request timing of the fuel injection section is in a time domain in which a current which is applied by the current output section changes transiently.
Claims3
A fuel injection device comprising:
- a current output section configured to output current for a request time based on control by a current control section;
- and
- a fuel injection section configured to inject fuel base on the current output by the current output section,
- where, in a case where an end timing of the request time is in a third time domain in which the current which is applied by the current output section changes transiently, the third time domain being between a first time domain where the current output section applies a first current amount to allow the fuel injection section to inject the fuel and a second time domain where the current output section applies a second current amount to allow the fuel injection section to continue to inject the fuel, the current control section being configured to correct the end timing of the request time by a correction amount based on the first current amount, the second current amount, and a period of the third time domain.
