1. OVERVIEW
The ignition system is to supply high voltage generated from the ignition coil to the spark plug.
The G20DF engine is equipped with the independent type direct ignition system that the ignition
coil is installed in each cylinder.
The basic ignition timing in each cylinder is determined by the signals from camshaft position
sensor and crankshaft position sensor.
This ignition system controls the electronic ignition timing received from the engine ECU. To
control the ignition timing precisely, the ECU use the information below:
- Engine load
- Coolant temperature
- Intake air temperature
- Engine rpm
- Camshaft position sensor (CPS)
- Crankshaft position sensor (CKS)
If the signal from the camshaft position sensor is not delivered to the engine ECU, the ignition coil
and fuel system cannot be operated.
