Types Of Spark Plugs
- Aug 12, 2017 -

              Different classification methods can be divided into different categories. According to the calorific value, there are cold and hot type, according to the electrode material, there are nickel alloy, silver alloy and platinum alloy, etc. if more professional, the type of spark plugs are generally as follows:

              1. Quasi-type spark plugs: The insulating skirt part is slightly indented into the shell end face, and the side electrode is the most widely used one outside the shell end surface.Spark Plug

              2, the edge body prominent type spark plugs: The insulating body skirt part is longer, protruding outside the shell end surface. It has the advantages of high heat absorption, good anti-pollution ability, and can be directly cooled by the inlet air to reduce the temperature, so it is not easy to cause hot ignition, so the heat adaptation range is wide.Spark Plug

              3, electrode type spark plug: its electrode is very fine, the characteristic is the spark is strong, the ignition ability is good, in the cold season also can guarantee the engine to start quickly and reliably, the hot range is wide, can satisfy many uses.

              4, Seat type spark plugs: the shell and screw into the thread of the cone, so do not use washers to maintain a good seal, thus reducing the spark plug volume, the engine design more favorable.Spark Plug

              5, Polar type spark plugs: The side electrode is generally two or more than two, the advantage is the ignition reliable, the gap does not need to adjust frequently, therefore in the electrode easy to ablation and spark plug gap can not often adjust some of the gasoline engine often used.

              6, Surface jump Fire type spark plugs: That is, along the surface gap type, it is one of the most cold type of spark plugs, the center of the electrode and the shell between the end of the gap is concentric.Spark Plug

             In addition, in order to restrain the interference of the automobile ignition system to the radio, the resistor and shielding spark plugs are produced. Resistive spark plugs are fitted with 5-10kω resistors in the spark plugs, and the shielded spark plugs are sealed with a metal shell to shield the entire spark plug. Shielding spark plugs can not only prevent radio interference, but also for waterproof, explosion-proof occasions.Spark Plug
