5.1 ignition system

The key diagram of ignition elements ignition elements:

Ignition pressure provided by magneto ignition coil

through diode commutated,by R(red line)input CDI(capacitance

discharge ignition),charge to capacitance C.at the same

time ,spring coil produce spring signal ,provided to SCR as the

turnon spring signal ,when reaching the ignition timing,SCR

turnon capacitance began to discharge at the elementary coil

L1 caused instant lower pressure ,while at the secondary coil

caused induce pressure.its instant pressure up to

10000V,sparkover at the clearance of sparkplug(0.6mm).so the

engine ignited
