Ignition

The ignition in a petrol engine ensures that the mixture of petrol and air is ignited at the end of the compression stroke. In most petrol engines, the ignition system consists of one or more (pin) ignition coil(s), spark plugs and an ECU or engine control unit to control everything. Depending on the system and the age of the vehicle, a different type of ignition may be used. For example, older vehicles are equipped with a central ignition coil which distributes power to the spark plugs via ignition cables. Newer petrol engines are often equipped with separate ignition coils, each cylinder having its own ignition coil.

A diesel engine is a self-igniter, i.e. due to the heat of compression, the diesel fuel and oxygen ignite by themselves and therefore do not need an external spark. However, a diesel engine does have a glow plug system which consists of a glow module and glow plugs (also called glow pins). When cold starting, this system helps to make the cold diesel engine start faster. When the vehicle gets a bit older, these common malfunctions will cause a diesel engine to start poorly (when cold).
