Traditional igniter has been not suitable with requirement.The core component of igniter is ignition coil and switching device, is improved
The energy of ignition coil, spark plug can generate the spark of enough energy, this is that igniter adapts to Modern Engine operation
Primary condition.
There are two groups of coils, primary coil and secondary coil inside common ignition coil.The thicker enamel-cover of primary coil
Line, usually with 0.5-1 millimeters or so of enameled wire around 200-500 circles or so；The thinner enameled wire of secondary coil is usually used
0.1 millimeter or so of enameled wire is around 15000-25000 circles or so.Primary coil one end couples with low-tension supply (+) on vehicle, another
End couples with switching device (circuit breaker).Secondary coil one end couples with primary coil, and the other end couples with high pressure line output terminal
Export high-voltage electricity.Why low tension on vehicle can be become high voltage by ignition coil, be identical with common transformer due to having
Form, primary coil are bigger than the turn ratio of secondary coil.But ignition coil working method and common transformer are different, commonly
The working frequency of transformer is fixed 50Hz, also known as Industrial Frequency Transformer, and ignition coil is worked with impulse form, can be with
Regard pulse transformer as, energy storage and exoergic is repeated with different frequencies according to the different rotating speed of engine in it.Work as primary
When coil switch power, a very strong magnetic field is generated with the growth surrounding of electric current, iron core stores magnetic field energy；When switch fills
Set make primary coil circuit disconnect when, the magnetic field of primary coil is decayed rapidly, and secondary coil will induce very high voltage.Just
The magnetic field disappearance speed of grade coil is faster, and the electric current that electric current disconnects moment is bigger, and the turn ratio of two coils is bigger, then secondary coil
The voltage induced is higher.
Overboard in the igniter of machine, due in water general work, leading to the humid environment of device work, and revealing for a long time
In it environment, when raining, moisture is more, and the existing waterproof and dampproof mode of ignition coil is that ignition coil carries out dipping lacquer processing,
That there is insulated paint insulation performances itself is low for paint-dipping process, dipped type is poor, maximum operation (service) temperature is low.
