Engine Ignition - INGENIUM I4 2.0L Petrol : Overview

WARNING: This page is about a different variant/trim than selected.

The 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 plugs are installed one per cylinder, between the intake and exhaust valves. An ignition coil is installed on each spark plug.

The spark plug is a device for delivering electric current from the ignition system to the combustion chamber. The spark plug is connected to the high voltage generated by an ignition coil. As current flows from the coil, a voltage develops between the central and side electrodes. The spark plugs feature an Iridium-tipped center electrode, and a platinum-tipped ground electrode. When the voltage differential equals the required voltage, then the spark plugs and the stored energy is dissipated. In the spark-ignition engine an electric spark ignited the compressed fuel/air mixture in the combustion chamber.
