The spark plug type

Spark plug, commonly called the fire, it is the high-pressure wire (fire) from mouth to discharge high-voltage pulsed air breakdown between two electrodes, spark plug ignites cylinders to produce spark a mixture of gases. High-performance engines are the basic conditions of high-energy spark, the stability of the mixture mixing, high compression ratio.

The spark plug type:
According to the low calorific value to points, cold and heat, According to the electrode materials, nickel alloy, silver alloy and platinum alloys, If more professional, spark plug in the following several types:
1. Quasi type spark plug:
The skirt is the insulator, lateral contraction shell in shell electrode end face, is the most widely used one.

2. Edge body outstanding type spark plug:
Long skirt insulators, protruding from the shell outside surface. It absorbs heat resistant capacity, as well as good, and can directly affected by the air cooling and lower temperature, thus it is hot, hot fire range wide.

3. Electrode type spark plug:
The electrode is very fine, the characteristic is strong, the spark ignition ability is good, can guarantee in the cold season starting engines quickly reliably, hot wide to meet a variety of USES.

4. Block type spark plug:
The shell and goes into tapered, so no thread can keep good sealing gasket, thus narrowing the control cable of engine, the volume is more favorable to the design.

5. A type of spark plugs:
Lateral electrode for two or more commonly, the advantage is the ignition, reliable, and need not often adjust, between the electrode gap spark erosion and easy to adjust some can often gasoline engines often use.

6. Surface fire spark jump type:
Namely the gap, it is one of the most cold, the center of spark plugs and shell electrode surface is one of the clearance between. In addition, in order to inhibit ignition system of radio interference, and produce resistance and shielding spark plugs. Resistance-type spark plug in the spark plug is equipped with 5-10k resistance, shielding type using metal shell is the spark plug the spark plug seals shielding. Not only can prevent spark shielding radio interference, also can be used for waterproof, explosion-proof occasions.
