Abstract
An optical sensor provides information about the burn of the fuel mixture in the combustion chamber of an internal combustion engine as well as the timing and waveform of the spark that ignites the fuel mixture in the combustion chamber. The optical sensor can be implemented as a stand-alone device, or incorporated into a spark plug.
