Development of a Spark Plug with High Ignitability and Wear Resistive Electrode

Abstract

In the small vehicle category, both ignitability and low cost are requirement. Currently the high ignitability spark plug does not meet the second requirement since they contain precious metals like Platinum and Iridium on their electrode. Considering these circumstances mentioned above, we have developed a superior wear restive material to achieve a fine-wired electrode design without the use of precious metals. Based on this development, we have introduced a new Super Ignition Spark Plug that achieves both high ignitability and low cost.
