4. Fuel Injection System
4-6
Ignition System Outline
Principle
ECU determines the appropriate ignition timing by receiving the signals from the CPS, TPS, O
2
Sensor,
MAP Sensor, TA Sensor and TW Sensor in accordance with the engine RPM. The ignition coil produces
25000~30000 volts to fire the spark plug, maximizing the engine output, and improving the fuel
comsumption efficiency.
