Sensor-integrated spark plug M14x1.25 6118C
Engine cylinder pressure measurement! No need for measurement hole processing!
The sensor-integrated spark plug (measurement spark plug) model 6118C... allows for in-cylinder pressure measurement without the need for a separate measurement hole. This plug is equipped with a piezoelectric in-cylinder pressure sensor that is among the smallest in the world for high-temperature applications. －＊ Features ＊－＊－＊－＊－＊－＊－＊－＊－＊－＊－＊－＊－＊－ • Modular design: Sensor cable and ceramic are replaceable • High insulation resistance – Maximum ignition voltage of 40 kV • High-precision sensor with flash mount • Long-life ignition system using platinum for both electrodes • Options for heat value and spark position selection
basic information
The measuring spark plug model 6118C... is available in various heat ratings, spark positions, and shapes. Electrical connections are made via SAE or CUP cable connector nuts. Ceramic insulators are available in diameters of 7.7 mm, 9 mm, or 10.5 mm. By slightly offsetting the electrode by 0.6 mm, space is created for incorporating the sensor. The sensor is inserted from the underside of the plug and secured with a small hole screw that also provides flame protection.
