Engine Ignition - V6 S/C 3.0L Petrol (G1903641): Overview

The V6 3.0L Petrol engine ignition system is a coil-on-plug, single spark system controlled by the Powertrain Control Module (PCM).

The spark plug is installed in each combustion chamber, between the inlet and exhaust valves, and an ignition coil is installed on each spark plug.

The energy stored in the ignition coil, manifests itself on the spark plug in terms of a voltage differential between the electrodes. When the voltage differential equals the required voltage, then the spark plugs and the stored energy is dissipated. An ignition coil is installed on each spark plug. A Radio Frequency Interference (RFI) suppressor is connected to the power feed to the ignition coils.
