摘要： A spark plug (20) for being threaded into a cylinder head (28) includes a shell (24) with threads (26) disposed at a predetermined angled relative to the ground electrode (34). The position of the threads (26) relative to the ground electrode (34) places the ground electrode (34) in a predetermined position in the combustion chamber (22) and relative to components of the engine, thus allowing the ground electrode (34) to provide a robust and reliable ignition. The threads (26) are formed by a thread forming apparatus (102) that includes an orientation tool (38) to position the ground electrode (34) relative to a thread forming apparatus (102), allowing the thread forming apparatus (102) to form the threads (26) at the desired angle (α).

摘要： A spark gap arrangement includes a discharge chamber, an electrode head and a contact connection arranged outside the discharge chamber. The electrode head is electrically conductively connected and mechanically coupled to the contact connection in such a way that, when the contact connection is removed from its position or when the contact connection reaches a preset position, the electrically conductive connection is interrupted, and the electrode head is mechanically decoupled from the contact connection so that the electrode head is movable in the direction of the discharge chamber interior and/or within the discharge chamber.

摘要： An assembly includes an engine main body, a spark plug and a gasket. The spark plug is mounted to the engine main body by tightening a male-threaded portion of the spark plug into a female-threaded portion of the engine main body with the gasket elastically deformed between a seat surface of the engine main body and a seating surface of the spark plug. The gasket is made of a metallic material whose yield stress or 0.2% proof stress is not lower than 200 N/mm2. The gasket has first and second contact surfaces respectively in contact with the seating surface of the spark plug and the seat surface of the engine main body. The first and second contact surfaces of the gasket are each formed as a part of a curved surface that has a convex shape, and are offset from each other in a radial direction of the spark plug.
