Abstract

A device is proposed for monitoring the combustion process in internal combustion engines, a direct monitoring and a monitoring of individual combustion processes, in particular individual combustion chambers, being possible. This is achieved using a waveguide, which is integrated in a component, which protrudes into the combustion chamber.
