[Features, Structure]
■D-Shape outer electrode with new material and center electrode with ruthenium!
As a spark plug for exclusive use in motorcycles, it has improved the various performances (acceleration, durability, anti-fouling, fuel efficiency, startability, etc.) required of spark plugs.
The D-shaped outer electrode (D-Shape outer electrode) and the ruthenium blended center electrode realize outstanding combustion efficiency.
■The D-Shape outer electrode is an electrode shape that does not obstruct the flow of the air mixture!Efficiently directs the air mixture into the spark gap.
■The D-Shape outer electrode is an electrode shape that does not inhibit the spread of the flame!More spherical and ideal combustion.
[About the shape of the plug terminal] ● Select the terminal with the shape that suits the engine and plug cord installation side.There are three types of plug terminals: integrated type, separate type, screw type, and punch-and-caulk type.Mainly, "integral type" and "punch caulking type" are used for four-wheeled vehicles and "screw type" for two-wheeled vehicles, and "separate type" is available for plugs used for both four-wheeled and two-wheeled vehicles.In addition, the terminal part of the "separate type" can be removed, but the terminal part of the "integrated type" and "punch-and-caulk type" cannot be removed.If you try to remove it forcibly, the terminal part may be broken.In case of using the "separate type" as the "screw type", remove the terminal nut.When using the product with the terminal nut attached, make sure that it is not loose, and if it is loose, tighten it lightly with pliers or the like.
[Features of NGK plug] |
- Super "wide range" plug - |
The center electrode has a "copper cored" structure with copper sealed up to near the tip so that a large amount of heat can be released quickly.The result is an ultra "wide range" plug that is resistant to burning and smoldering. |
Comparing the thermal characteristics of plugs with a copper core and plugs without a copper core, plugs with a copper core excel in thermal characteristics and fouling resistance, and have a wider heat range. |
■ Heat value of the plug |
- New ceramics high alumina porcelain is used as the insulator - |
- Excellent insulation at high temperature and reliable sparking.・Excellent heat conductivity and prevents seizure.・High thermal shock resistance (rapid heating and cooling) and excellent mechanical strength. |
- Strong and airtight in construction - |
Because the insulator and the main metal fittings are joined by special powder, it is excellent in airtightness and strong in structure. |
Special nickel alloy electrodes are used for superior durability. |
- Corrugations in the insulator ensure insulation and prevent flashover - |
During sparking, a high voltage is constantly applied between the terminal and the main unit bracket.High voltages try to leak along the surface of the insulator and flashover is more likely to occur if the required voltage between the spark gaps is high.In order to prevent flashover, insulator corrugations (folds) are provided to increase the insulator surface distance between the terminal and the main fittings to ensure insulation and prevent flashover. |
What is a flashover... |
It is a spark between the terminal and the main unit fitting as shown in the image. |
