Abstract
A spark plug for a stationary, gas-powered internal combustion engine, having a metallic body, an insulator mounted in a passage of the body, a center electrode passing through the insulator, a ground electrode mounted on the body that, together with the center electrode, forms a spark air gap, and a cap attached to the body. The cap shields the center and ground electrodes from the combustion chamber after the spark plug is installed in a combustion chamber of the internal combustion engine, and that, together with the body of the spark plug, forms a prechamber in which the center and ground electrodes are located. The cap has at least one opening that permits gas exchange between the prechamber and the space outside of the prechamber. A sensor receiving space is provided in the body of the spark plug, which space opens into the prechamber and serves to receive a pressure sensor in a replaceable manner, and a connecting channel for routing a connecting line of the pressure sensor leads from the sensor receiving space to the end of the body opposite the cap.
