Arrangement for monitoring combustion process in combustion engines has component that can be introduced into combustion chamber contg. waveguide for infrared or visible light

摘要

The arrangement has a component (2) that can be introduced into a combustion chamber that contains a waveguide (6) for electromagnetic radiation. The waveguide is conducting in the infrared or visible region. A radiation intensity sensor is mounted on the output of the waveguide. Independent claims are also included for a glow plug and an ignition plug for an internal combustion engine.
