Ignition coil converts the low voltage of the primary winding into the high voltage of secondary winding
and discharged at spark plug to ignite the fuel air mixture in cylinder.
This engine adopts independe
nt ignition technology and utilizes the theory of
high energy utilization by
the mutual inductance of electromagnetic coil to control the energization time and power-off moment of
the secondary coil and utilize the high voltage generated in the secondary stage of the coil to puncture
the gap of spark plug, generate strong spark, and ignite the gas mixture. Due to high air ionization
degree and low resistance during engine exhaust stroke, it only needs a low voltage to puncture the gap
of spark plug. Therefore, this system adopts grouped ignition technology, which will not waste any
energy and will save a great amount of cost.
Ignition coil operating voltage range: 6 - 16V
Secondary ignition coil resistance: 8.7 ± 0.87 KΩ
Primary charge time: 2.15ms
Minimum ignition duration: 1.0ms
Minimum ignition energy: 35mJ.
