Compared to older competitive designs, E3 Spark Plugs’ patented DiamondFire technology was recently and conclusively proven to provide more rapid and robust combustion by research engineers at Michigan Technological University.
In reality, spark plug technology hasn’t changed much since the original “J-Wire” side-wire electrode was developed and patented in 1904 and used in the Model T Ford. Real-time combustion images were captured during advanced testing methods employed at Michigan Tech, a nationally acclaimed automotive research facility, to show a comparison between conventional competitive designs and E3’s revolutionary DiamondFire technology. The images prove that E3’s “diamond-shaped” side-wire electrode projects the combustion spark in a way that more quickly ignites the air/fuel mixture, thereby creating a significantly faster and larger flame kernel.
In effect, this burns more of the available fuel, resulting in increased combustion efficiency for improved power and fuel economy with reduced emissions.
“I have had an active role in the automotive industry for about forty years, so new technology surprises are rare to me. However, I was pleasantly surprised by the scientific data from Michigan Tech when they tested the new E3 technology”, stated Jim McFarland, veteran automotive engineer, and Research consultant for E3.
While conducting engine dyno tests comparing E3 technology to competitive brands, Jeremy Worm, lead Research Engineer for the Advanced Power Systems Research Center at Michigan Tech stated, “We found that the E3 spark plug produces a faster burn, especially in the early stages of the combustion process. In an engine, the early burn duration translates to the stability of the combustion process. By making that early burn more stable, we can run more dilution in the cylinder, and that directly translates into improved engine efficiency.”
Backed by a five year, 100,000-mile warranty, E3 Spark Plugs with DiamondFire technology, are now available for most automotive and motorsports applications at automotive retail stores nationwide. For more information and complete test results, visit www.e3sparkplugs.com.
