If you’ve ever been faced with an engine quitting out on the trail or up on the mountain, there’s a good chance it was because of spark plug fouling. But new technology is making today’s snowmobile spark plugs more efficient, which reduces fouling, helps engines last longer, and keeps the environment cleaner.
Here’s how. In the last 100 years, the only real advance in spark plug technology has been to add special metals to extend life and to learn how to make them cheaper – not better. The standard J-wire electrode has been just that – standard.
New advanced designs, such as E3 DiamondFIRE spark plugs, offer a faster forming and larger flame kernel, and therefore more complete fuel combustion. The result: more power, cleaner engines, and reduced emissions. The open, diamond-shaped architecture of the electrode is the secret behind E3’s ability to provide cleaner, more complete fuel burn.
The efficiency and performance of the plug is mostly determined by the shape of the electrode. When a spark plug fires, the spark seeks the edges of the electrode surfaces. Traditional J-wire plugs have limited edge surface area. But the “open architecture” of E3 spark plugs provides more sharp edge surface for better spark generation and less wear.
The E3 DiamondFIRE spark plugs feature a diamond-shaped electrode with a revolutionary “Edge-to-Edge” design. The unique geometry of the E3 provides optimized spark paths well into the useful life of the spark plug. This patented design delivers forced edge-to-edge spark discharges, which are proven to be the most efficient and effective way to get a spark to leave a surface. DiamondFIRE technology allows the fastest flame-front to grow unimpeded towards the piston to create a more complete burn of the fuel/air mixture in the cylinder.
Flame shape is critical, too. Old-technology J-wire plugs create a flame shape that moves sideways, outward from the electrode. But the open, diamond configuration of E3 spark plugs shapes the flame, aiming it accurately toward the piston head and fuel/air mixture to create higher combustion pressure, practically perfect fuel burn, and greatly reduced deposits on the cylinder heads and electrode surfaces.
There is another advantage to DiamondFIRE technology, and it has to do with what spark plugs are made of. The limited edge surface of the J-wire electrode causes the spark to strike the same places over and over, so the metal wears down relatively quickly. Many manufacturers use precious metals such as platinum or iridium, because they’re attempting to extend plug life. The DiamondFIRE design of E3 spark plugs accomplishes extended life without the use of special metals… because the geometry and shape of the electrode provide more spark surface, and less overall wear.
Laboratory testing showed that E3 spark plugs improved power output in typical engine operating ranges, and reduced fuel consumption. The more completely you burn the fuel, the greater the power output – and the less hydrocarbon residue is left behind to foul plugs – and stop engines cold.
