69M3E11 1-6123456789Features and benefits 1Ignition systemA simple and compact ignition system is adopted. In this ignition system, high voltage is induced inthe secondary coil when the electric current produced by the primary coil and the permanent mag-net on the rotating flywheel is cut off.This TCI (Transistor Controlled Ignition) system greatly contributes to a compact and lightweightengine.1 TCI unit2 Permanent magnet3 Flywheela Air gap: 0.4–0.6 mm (0.016–0.024 in)1 Flywheel2 Permanent magnet3 Core4 Primary coil5 Secondary coil6 Spark plug7 Transistor 18 Transistor 29 Engine shut-off switchS69M11301 2 3456789Identification / Features and benefits
