A spark plug electrode is made by locating a core of thermally conductive metal co-axially in the box of a tubular outer metal sheath. The sheath is worked down on the core. The core is removed from a region at one end of the sheath and the sheath is melted where core is removed to...
Melted electrodeA symptom of severe preignition. The spark plug has been running too hot for a long time (see overheating above). This can be very damaging and may burn a hole through the top of a piston! SPARK PLUG REPLACEMENT TIPS When spark plugs are replaced, wqe would recommend upgra...
A method of manufacturing a center electrode for a spark plug, the method including the steps of: resistance welding a sphere of a noble metal to a center electrode of a spark plug to provide a center
Plasma Ignition.In plasma ignition spark plugs, the body acts as a side electrode. Thanks to their design, which forms a spark ring gap, the spark moves in a circle, which contributes to the self-cleaning of the spark plug, thereby increasing its service life. How Long Do Spark Plugs Last?
A blistered white insulator or melted electrode indicates over-advanced ignition timing or a malfunctioning cooling system. If correction does not prove effective, try a colder grade plug. . BURNT OIL White deposits have accumulated from excessive amounts of oil in the combustion chamber or through...

An igniter generates a plasma, or spark, somewhat similar to an automotive spark plug. In the invention, an auxiliary electrode is provided, which is embedded in and covered by a solid insulator. Duri... RL Ponziani,R Earwood - US 被引量: 4发表: 2005年 Igniter for gas turbine engine ...
the flame quenching effect of the electrode is suppressed, and the ignitability is increased. Thus, the ignitability of the spark plug can be increased with a simple structure. Since the recess is formed in the melted portion, the recess can be easily formed. In addition, since the projection...
A spark plug which exhibits improved resistance to high-temperature oxidation of an electrode, and improved resistance to spark-induced erosion of, improved resistance to oxidation
