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.

Fuel injection valve spark plug combination

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.

Combined fuel injection valve/ignition plug

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 for igniting the fuel injected into the combustion chamber, and has a spark-plug insulator including a first electrode, and includes a second electrode. The fuel injector and the spark-plug insulator of the spark plug are each disposed in a recess of a cylinder head of the internal combustion engine. The fuel injector and the spark-plug insulator of the spark plug are fixedly held in place in a shared connecting member arranged outside of the cylinder head.

Fuel injector-spark plug combination

A spark plug includes a shell on which a threaded shank having a thread and a tool attachment for installation in an internal combustion engine are situated, and an assembly shank of the shell running between the threaded shank and the tool attachment. The spark plug is dimensioned in such a way that the ratio of the sum of the threaded shank length and the assembly shank length to the sum of the assembly shank diameter and the thread diameter is between 0.95 and 1.55.

Spark plug

A spark plug for an internal combustion engine includes a middle electrode which has an electrode base body ( ) with an end face ( ) oriented toward the combustion chamber, to which end face a precious metal platelet ( ) is attached. An end section ( ) of the electrode base body oriented toward the combustion chamber is formed in the shape of a truncated cone. The precious metal platelet ( ) is likewise formed in the shape of a truncated cone and the diameter of the end face ( ) of the electrode base body oriented toward the combustion chamber corresponds to the diameter of the end face ( ) of the precious metal platelet oriented away from the combustion chamber. A method for producing middle electrodes for a spark plug of an internal combustion engine is also proposed.

A spark plug is described having a partially cylindrical insulator element and a housing surrounding the insulator element on the side of a base part. The insulator element and the housing are connected with one another by at least one material bond and/or one friction-lock connection aligned in the radial direction. A compact spark plug can be produced using this type of connection. In particular, the diameter of the spark plug is smaller than the diameter of known spark plugs having the same characteristics.
