Title:
ELECTROMAGNETIC FUEL INJECTION VALVE AND CONTROL DEVICE FOR FUEL INJECTION VALVE
Document Type and Number:
Japanese Patent JP2016188576
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To solve such the problem that there are possibilities of causing complication of an inner structure of a fuel injection valve due to addition of materials and causing application of a load to a valve body and occurrence of deformation of the valve body depending on variations of members to be stretched.SOLUTION: There is provided a fuel injection valve which is configured such that in order to change an injection period and correct stroke amount variations due to variations in manufacture and a secular change without significantly changing the structure, a detection member generating a voltage or current by an impact due to a collision is incorporated into an end face of a collision part of a movable element or an end face of a collision part of a magnetic core to control injection pulses by differences in output times at the time of collision with this part, and thus an injection quantity can be controlled.SELECTED DRAWING: Figure 3
