FUEL INJECTION VALVE WITH IN-CYLINDER PRESSURE SENSOR

摘要

PROBLEM TO BE SOLVED: To prevent disconnection and the like of a signal transmission part connecting a sensor capable of detecting in-cylinder pressure of a combustion chamber to a signal terminal and to connect them easily and stably.SOLUTION: A signal transmission part 24 constituting a fuel injection valve 10 comprises a first signal transmission member 52 disposed on an outer peripheral side of a valve housing 40 and connected to a sensor 20, and a second signal transmission member 54 disposed on a solenoid part 14 and connected to a signal terminal 22. A housing part 68 is formed on a base end of a first conductive layer 58 provided inside the first signal transmission member 52. A first connection part 80 of the second signal transmission part 54 is inserted into a connection hole 72 of the housing part 68 and is electrically connected by solder 84 housed inside the housing part 68. The solder 84 has a ring-like shape so as to be inserted onto the first connection part 80 inside the housing part 68.
