Spark plug construction:
Spark plugs are one of the most misunderstood components of an engine. Numerous questions have surfaced over the years, leaving many people confused.
This guide was designed to assist the technician, hobbyist, or race mechanic in understanding, using, and troubleshooting spark plugs. The information contained in this guide applies to all types of internal combustion engines: two stroke engines, rotary engines, high performance/racing engines and street vehicles
This guide was designed to assist the technician, hobbyist, or race mechanic in understanding, using, and troubleshooting spark plugs. The information contained in this guide applies to all types of internal combustion engines: two stroke engines, rotary engines, high performance/racing engines and street vehicles.
Spark plugs are the “window” into your engine (your only eyewitness to the combustion chamber), and can be used as a valuable diagnostic tool. Like a patient’s thermometer, the spark plug displays symptoms and conditions of the engine’s performance. The experienced tuner can analyze these symptoms to track down the root cause of many problems, or to determine air/fuel ratios.
Operation:
The plug is connected to the high voltage generated by an ignition coil or magneto. As the electrons flow from the coil, a voltage difference develops between the central electrode and side electrode. No current can flow because the fuel and air in the gap is an insulator, but as the voltage rises further, it begins to change the structure of the gases between the electrodes. Once the voltage exceeds the dielectric strength of the gases, the gases become ionized. The ionized gas becomes a conductor and allows electrons to flow across the gap. Spark plugs usually require voltage of 12,000–25,000 volts or more to 'fire' properly, although it can go up to 45,000 volts. They supply higher current during the discharge process resulting in a hotter and longer-duration spark.
As the current of electrons surges across the gap, it raises the temperature of the spark channel to 60,000 K. The intense heat in the spark channel causes the ionized gas to expand very quickly, like a small explosion. This is the 'click' heard when observing a spark, similar to lightning and thunder.
The heat and pressure force the gases to react with each other, and at the end of the spark event there should be a small ball of fire in the spark gap as the gases burn on their own. The size of this fireball or kernel depends on the exact composition of the mixture between the electrodes and the level of combustion chamber turbulence at the time of the spark. A small kernel will make the engine run as though the ignition timing was retarded, and a large one as though the timing was advanced.
PHOTOS SHOW:
have the following fetures:
1) Multi-ribbed insulator eliminates flashover.
2) 95% pure alumina insulator, Great mechanic and electronic features, superb insulation.
3) Nickel plated housing prevents oxidation and corrosion, Heat crimping process ensures absolute air-tight fit.
4) Inner sealing with conductive glass ensures a fine conductivity and sealing.
5) Multi-layer gaskets have strong elasticity and reliable in sealing.
6) Copper core electrode vastly improves heat dissipation and prevents dangerous, overheating of the engine. From Chinese factories spark plug/ngk spark plug is very delicate and durable
7)Good electricity and heat conductivity, Long spark plug service life
