Abstract
A fuel injector-spark plug combination comprises 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, a first electrode and a second electrode for igniting the fuel injected into the combustion chamber. The fuel injector includes an actuator cooperating with an actuation device, which is in force-locking, operative connection to a valve needle, the valve needle, or a valve-closure member connected thereto, cooperating with a valve-seat surface to form a sealing seat. The valve needle of the fuel injector and the spark-plug insulator of the spark plug are positioned in a shared housing at a biaxial offset.
