Partakers boards conventional ignition system used on the car has a long history,
now has gradually been replaced by direct ignition system (DIS)
Direct ignition system is divided into three types：
▲dual ignition system using double-ended output ignition coil (DEC).
▲single ignition system using single-ended output ignition coil (CPC).
▲Integrated ignition system using the integrated spark plug (COP).
The common feature of these three is the output of the ignition coil pass directly
to the spark plug without passing through the distributor plate
2）Traditional ignition system
Traditional ignition system consists of a battery, cam, breaker, ignition coil, distributor,
spark plugs. The effect of battery is to supply power of the ignition system require, cam
and the circuit breaker turn on or off ignition system power. Ignition coil store ignition
energy and turn battery voltage to ignition high voltage. The role of the circuit breaker is
turned on or off ignition primary circuit. The role of the distributor is to delivery ignition high
voltage produced by ignition coil to each spark plugs according to working order of engine.
Spark plugs lead ignition high voltage to cylinder combustion chamber, and produce spark
between the electrodes, Igniting the combustible mixture.
The advantage of this ignition system is relatively easy for detection service, one of
the disadvantage is mechanical parts and electrical contacts easy to wear, short life. And
the high-voltage connector portion also easily damaged.
3）Dual ignition system (DEC)
Dual ignition system entirely by electronics, with no mechanical parts. Each two
cylinder shared a ignition coil, two electrodes of coil secondary connect to a spark plug
respectively. It means that there are always two spark plugs igniting at the same time, one
of the cylinders in the normal ignition, the other cylinder is at the exhaust process (Ignition
spark "waste" in the exhaust gas), the pressure of cylinder in exhaust close air pressure,
only need very low ignition voltage, wasted little energy.
One of the advantages of dual ignition system is fewer faults, virtually no maintenance.
Another advantage is the good adjustability of the ignition system; wave radiation emitted
