COMBUSTION PRESSURE SENSOR AND GLOW PLUG |
摘要 |
[Objective] To improve the accuracy in detecting combustion pressure by a sensor element. [Means for Solution] An elastic member of a combustion pressure sensor has a first tubular portion joined to a rod-like member; a first curved portion extending radially outward from a portion of the first tubular portion on the rear end side thereof; a second curved portion extending radially outward from a portion of the first curved portion on the outer circumferential side thereof; and a second tubular portion connected to a housing. The housing has a forward end portion which constitutes an opening portion, accommodates at least a portion of the first tubular portion, the first curved portion, the second curved portion, and at least a portion of the second tubular portion, and forms a gap between the forward end portion and at least a portion of an outer surface of the second tubular portion. The combustion pressure sensor further comprises a wall portion which is disposed within the forward end portion to be located on the forward end side of the second curved portion and overlaps with at least a portion of the second curved portion as viewed in the axial direction. |
