Authors Abstract
Content
In a high gas velocity condition in cylinder, the ground electrode orientation of the spark plug causes the ignitability to fluctuate due to the change in gas flow around the spark gap. As one method to solve this issue we have focused on controlling the gas flow by plate like airfoils or turbine blades. We have developed gas flow control technology for the spark plug to achieve high ignitability under the worst case condition of ground electrode orientation. The adoption of current ground electrode welding technology has allowed us to locate a flow guide plate on the plug housing.
