Spark (spark plugs), commonly known as the burner, it is the role of the high-voltage wires (spark plug wires) sent to the pulse high-voltage electric discharge breakdown between two electrodes of spark plug air, electrical discharge to the introduction of mixed gas in the gas tank. Basic conditions for high-performance engines: high energy spark, uniform mixing of the mixture of stability, high compression ratio.
Where the gasoline engine has spark plug, a cylinder a, high speed gasoline engine also has 2 spark plugs for each cylinder. Spark plugs spark plug is only a small part, but it is extremely important to launch opportunity to move without it. Men who often drive will be very familiar with this thing.
Spark plugs are high voltage ignition coils (over 10,000 volts) introduction of engine cylinders, spark plug electrode gap between spark ignited mixture. Spark plug of work environment is bad, to a Taiwan General four stroke gasoline engine of spark plug for cases, in intake stroke Shi temperature only 60 ℃, pressure 90KPa; and in ignition combustion Shi, temperature will moments rose to 3,000 ℃, pressure reached 4000KPa; this anxious cold anxious hot of alternating frequency is high, not General material by can meet got, also to guarantee insulated performance, so on spark plug of material requirements also on is demanding has.
