1, quasi-type spark plug: insulator skirt slightly into the shell end, side electrode in the shell outside the face, is the most widely used one.
2, the edge of the prominent type of spark plug: the insulator skirt longer, protruding outside the end of the shell. It has a large heat absorption, good anti-fouling and other advantages, and can be directly by the intake of the cooling and reduce the temperature, which is not easy to cause hot ignition, so the heat to adapt to a wide range.
3, the electrode type spark plug: the electrode is very fine, characterized by a strong spark, ignition ability, in the cold season can also ensure that the engine quickly and reliably start, a wide range of heat to meet a variety of purposes.
4, seat spark plug: the shell and screw into the screw made of cone, so no gasket can maintain a good seal, thereby reducing the spark plug volume, the engine design is more favorable.
5, very spark plug: side of the electrode is generally two or more, the advantage is reliable ignition, the gap does not need to adjust frequently, so easy to ablate the electrode and the spark plug gap can not often adjust some of the gasoline engine is often used.
6, surface flashing spark plug: that is, along the gap type, it is a cold type of spark plug, the center electrode and the shell between the end of the gap is concentric.
In addition, in order to suppress the car ignition system on the radio interference, and the production of resistance and shielded spark plug. Resistive spark plug is installed in the spark plug 5-10kΩ resistance, shielded spark plug is the use of metal shell to seal the entire spark plug seal. Shielded spark plugs not only prevent radio interference, but also for waterproof, explosion-proof occasions.
