Basic Introduction to Spark Plugs & New Spark Plug Technology
As natural gas engine efficiencies continue to rise, there is an ever-increasing demand for longer life spark plugs. The design of a spark plug certainly has an important part to play in determining its useful life, and much development is being done to design a spark plug that will last at least as long as the engine service interval. Current production designs are constantly being evaluated for performance and customer satisfaction. These evaluations often highlight a requirement for new designs offering longer life in certain applications. Field testing and customer feedback are part of the continual development process. In addition to spark plug design, many other factors are critical in determining spark plug life. These include cylinder head design, spark plug installation, the ignition system, ignition timing, fuel and combustion chamber conditions.
