Product Description

E3 Lawn & Garden Spark Plugs with DiamondFIRE Technology generates more power on less fuel, while dramatically reducing hydrocarbon emissions. E3 L&G spark plugs have a limited lifetime guarantee.

Amazon.com

E3 Lawn & Garden and Small Engine spark plugs are a clear breakthrough in spark plug technology. Developed by researchers from leading engineering universities, E3's patented electrode design allows for a better spark, and resulting more complete flame kernal and flame front extending off the electrode, producing better overall localized pressure inside your small engine's cylinder(s). This in turn leads to the fuel/air mixture injected into the cylinder being more cleanly consumed, lessening the level of greenhouse gases emitted, increasing energy efficiency and generating more horsepower.

Why You Need E3 Spark Plugs
As the designated catalyst for the ignition of fuel in small engines, spark plugs are a small, but constant factor in the workings of the vast majority of lawn and garden tools utilizing such motors. What owners of these tools may not realize is that their choice of spark plug could play a significant role in reducing the level of greenhouse gases that their engines give off, as well as increasing their overall fuel economy and potential power output. This is where E3 Spark Plug's DiamondFire technology comes in.

DiamondFire Technology
For the last 100 years, the only real advance in consumer spark plug technology has been to develop ways to make them cheaper. E3 Spark Plug's DiamondFire technology changes all of that through an improved electrode design that provides for more efficient burning of your engine's air/fuel vapor, leading to more pressure in the cylinder. These improvements are measurable, confirmed and based on the following design elements found in existing performance spark plugs.

First, the DiamondFire electrode directs the flame kernel to the piston more directly, reducing the travel time from the spark zone to the end gases via the open section at the top of the electrode. Given the short time available to get combustion started, the faster you can get the flame to the piston, the better. Second, the physical features of the electrode project further forward into the combustion chamber. This brings the spark zone closer to areas of probable "good" air/fuel mixture and also creates beneficial "micro-aerodynamics" within the spark zone. The initial combustion wave leaves the spark area at supersonic speeds above Mach 1, and the elevated edge provides a kind of chimney effect so the next round of air/fuel mixture gets into the spark zone more easily. Finally, the E3 electrode design features forced edge-to-edge spark discharge, which is the best way to get a spark to leave a surface. This improves upon the phenomena that drove race car drivers to "cut back" ordinary electrode spark plugs in order to improve the spark discharge. The spark itself occurs only when an avalanche of electrons migrates from the two electrodes (anode to cathode). Sharp edges are better at initiating electron migrations, and these accelerated electrons collide with matter inside the spark zone to release additional electrons. This design ensures that the whole population of electrons works to create a plasma channel through which the spark current flows more easily, resulting in an increase in both power output and fuel economy, while reducing emissions in gasoline engines and the build up of carbon deposits on engine surfaces.

Key Features:

  • DiamondFire electrode technology that creates a superior spark and resulting flame front extending further into the cylinder, producing more localized pressure.
  • Power increased > 6% to 12% (depending on engine class).
  • Fuel efficiency improved > 4% to 13% (depending on engine class).
  • Emissions reduced in 2 and 4-stroke engines (after 50 hours).
    • 58% CO emissions reduction.
    • 42% hydrocarbon reduction.
  • Near elimination of performance inhibiting carbon deposits.
  • Dramatically longer plug life.
  • Limited warranty for the lifetime of the first engine installed in.

Limited Warranty
E3 small engine spark plugs properly installed in noncommercial equipment, for household purposes are warranted to provide better performance than standard spark plugs, to properly discharge a spark, and to be free of defects in material or workmanship, for the life of the first engine in which they are installed. In the event of provable defect within the stated warranty period, the manufacturer will either replace the item(s), or refund the purchase price at their discretion.
