Abstract

A fuel injector-spark plug combination includes a fuel injector for the direct injection of fuel into a combustion chamber of an internal combustion engine and a spark plug with a spark-plug insulator, the spark plug having a first electrode, and a second electrode for igniting the fuel injected into the combustion chamber. The fuel injector and the spark-plug insulator of the spark plug are arranged at a biaxial offset in a respective receiving bore of a shared connecting member inserted in a recess of a cylinder head.
