Abstract
A spark plug having one or more cooling feature(s) that reduce the temperature of a ground electrode and can be manufactured using an additive manufacturing process. The cooling feature(s) include internal cooling passages that can be filled with either a heat conducting solid (passive cooling example) or a heat conducting fluid (active cooling example). In the passive cooling example, the internal cooling passage is filled with a heat conducting solid that is inserted into the passage, melted and solidified such that it forms a metallic bond with the walls of the passage. In the active cooling example, the internal cooling passage is filled with a heat conducting fluid that flows through the passage and removes heat from the ground electrode. In both examples, internal cooling passage(s) of the ground electrode are aligned with corresponding cooling passage(s) formed in the shell.
