Document Type and Number:
Japanese Patent JP2006307835
Kind Code:
A
Abstract:

To provide a structure for a spark plug having a combustion pressure detecting function provided with a gasket and an annular pressure sensor reducing sensor output loss and not producing gas leak.

The gasket used in the spark plug having a combustion pressure detecting function has Young modulus E 100kN/mm2 or more and 170 kN/mm2 or less and 0.2% yield stress is 250N/mms or less. The gasket having these properties can be formed out of copper base alloy containing 0.80-1.20 wt.% of Ni, 0.50-1.10 wt.% of Sn, 0.03-0.07 wt.% of P and 97.63-98.67 wt.% of Cu.
