Abstract

The sensor arrangement to determine oscillations arising upon knocking of a combustion engine uses at least one optical receiver, known per se, in the combustion chamber, preferably a glass rod 12 or a light guide cable of glass fibers 20. The optical receivers are either integrated in the spark plug, or connected to a pre-chamber, or inserted in the cylinder head seal.
