A piezoelectric crystal spark plug includes a body similar to a conventional spark plug, a central electrode extending from the bottom end of the body, and a ground electrode disposed near but spaced from one end of the central electrode and connected to the body. A piezoelectric crystal is included within the body and one side of the crystal is electrically coupled to the other end of the central electrode. A deforming device is also included within the body to deform the crystal and cause it to produce and apply an electrical signal to the central electrode. This electrical signal produces a spark between the central and ground electrode similar to a conventional spark plug. The deforming device can include a striker element for striking the crystal to deform it, a second low voltage piezoelectric crystal coupled to the first mentioned piezoelectric crystal so that when a low voltage signal is applied to the second crystal it deforms to thereby deform the first piezoelectric crystal, a solenoid disposed in the body to strike or apply a force to the piezoelectric crystal to deform it in response to a low voltage signal, or other suitable deforming devices.
