燃気量の振動検出装置。In an internal combustion engine in which a cylinder is surrounded by an outer skin through a cooling water passage, a blind hole-like center hole is formed from the other end of a metal rod provided with a contact beak portion that contacts one end portion, and the center hole is formed in the form of a blind hole. A metal damper and a piezoelectric element insulated against the inner circumferential wall of the center hole are sequentially inserted into the back end of the metal rod, and a voltage extraction electrode surrounded by an insulating ring is provided near the end of the center hole of the metal rod. The vibration detection sensor is passed through the cooling waterway from the outside of the outer skin so that the outer surface of the metal rod near the piezoelectric element is exposed to the cooling water, and the contact beak is mounted so as to be in contact with the outer surface of the cylinder liner. Vibration detection device for internal combustion air amount.
