New Design of Copper–Inconel 601 Ground Electrode Spark Plug Based on a Thermo-Mechanical Model

Abstract: Inconel 601 is one material of choice for intermediate- to high-temperature protective coatings for spark plugs’ ground electrodes. Production of ground electrodes of spark plugs implies the following operations: the tamping of the copper core in an Inconel 601 cup, cold-forming of the assembly, annealing, welding, and bending of the final spark plug. On the production line, the use of Inconel 601 as a protective coating for ground electrodes leads to possible cracking in the welded area after bending. In the … Show more

“…It is one of the smallest and cheapest operating elements of the internal combustion engine and performs one of the most important tasks, which is the initiation of fuel ignition in the cylinder. Using a worn or damaged spark plug, which operates at elevated temperatures in the combustion chamber, may cause uneven engine operation, a decrease in its power or increased fuel consumption [13,14]. The main tasks of the spark plug include the performance of a spark electric discharge of the required nature inside the combustion chamber while ensuring the repeatable operation of the engine in minimum isobaric and isothermal load conditions [15][16][17].…”
