Principle
The computer programmed ignition system receives the signals from the Crankshaft position sensor,
Throttle position sensor, O
temperature sensor. Calculating the engine RPM, the 16-bit microcomputer determines the appropriate
ignition timing, controls the ignition coil and triggers the spark plug. This way can not only make the
engine achieve the maximum power output, but also help improve fuel consumption rate.
