Engine Ignition: Overview

WARNING: This page is about a different car, the 2019 Jaguar XE. However, it is still accessible from the selected car via links, so may be relevant.

The V8 5.0L S/C Petrol engine ignition system is a coil on-plug, single spark system controlled by the Powertrain Control Module (PCM). For additional information, Refer to: ELECTRONIC ENGINE CONTROLS

The spark plug is installed in each combustion chamber, between the intake 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.
