摘要： In spark ignited engine configurations, it is common to provide a spark plug that has a spark gap that has dimension that will accommodate good starting capabilities for the engine. In some cases, this spark gap is larger than required for the engine to run efficiently, especially at high loads. As a result, the voltage required to bridge the gap when the engine is running at high loads is much higher than necessary and causes erosion of the electrode and a build up of deposits on the ground strap. Ultimately, this greatly reduces the life of the spark plug. The present invention provides a spark plug (10) that utilizes an adjusting means (50) that is connected to the electrode (42) of the spark plug (10) and functions to move the electrode (42) with respect to the ground strap (20) to adjust the gap (48) therebetween. The adjusting means (50) is responsive to the temperature of the spark plug (10) which will vary with engine loads or an increase in pressure within the combustion chamber (64).

摘要： A spark plug is disclosed and comprises: a metal tube which interiorly defines an axis and is externally-threaded for engine block engagement; an insulator having a portion which is disposed inside the tube and extends therebeyond; a positive electrode extending through the insulator and projecting beyond the extending portion of the insulator; and an annular ground electrode coupled to the tube. The electrodes are configured such that a spark gap defined therebetween comprises an elongate channel which opens axially and away from said insulator and is substantially unobstructed in the axial direction. The ground defines a void having: a central portion occupied by the positive electrode in use; an annular channel surrounding the central portion; and a plurality of lobes, each being positioned with respect to the central portion in a manner analogous to the placement of the planet gears with respect to the sun gear in a planetary gear
