ELECTRONIC IGNITION SYSTEM (TC-TXC-SMR 450 R)
In the C.D.I. system the electrical energy generated by the alternator charges the condenser.
The energy is released in a single surge at the specified ignition timing and the current flows through the primary side of the ignition coil.
A high voltage is induced in the secondary windings of the ignition coil, resulting a strong spark between the ignition spark plug gap.
The digital electronic ignition allows to change the timing curve according with the following items:
- ENGINE r.p.m.;
- CARBURETOR THROTTLE VALVE POSITION SENSOR;
- ENGAGED GEAR.
This system allows to optimize the engine performances in every condition of employment. In case of throttle valve or transmission gear
failure, the ignition is able to allow the use of the motorcycle however.
The electronic ignition system consists of:
- Electronic power unit (1);
- Alternator (2);
- Voltage regulator-rectifier (3);
- Condenser (4) (TC-TXC);
- Spark plug (8);
- Gear shift position sensor GPS (9);
- Ignition coil (10);
- Carburetor throttle position sensor TPS (11);
- Engine stop switch (12).

components, see pages M.4÷M.5.
