Combustion analysis via the spark plug bore

In close cooperation with Bosch and AVL, Piezocryst Advanced Sensorics has developed a novel spark plug series with integrated pressure measurement function for engine design and quality control. The partners have contributed their respective know-how to this cooperative venture (ignition from Bosch, application from AVL and sensor from Piezocryst). Special priority was given to the achievement of a high-quality pressure signal without the need for an additional bore in the engine. For this, completely new design approaches were pursued in order to solve the problems of extreme miniaturization.
