What provides ignition
The ignition system, sending a spark in a timely and targeted manner, ensures the correct combustion process of the fuel-air mixture in the engine. And this...

When does ignition occur?
The spark must jump at the right moment. The combustion of the fuel-air mixture occurs most efficiently at the moment when it is compressed to its minimum...

Ignition system
In our Vectra models, ignition is an element of the entire engine management system. This means combining ignition and injection control. The advantage of this...

This is how the ignition spark is created
The basic principle of ignition is that the battery current first flows through the primary winding of the ignition coil. This winding consists of several...

Ignition coils in a distributorless ignition system
Sometimes these ignition coils are called dual spark ignition coils (or DIS ignition modules), and this is for the following reason: with each ignition pulse...

The brain of the ignition system
Control unit In all engines, ignition control is combined with injection control. Therefore, there is a common electronic control unit. Here is a short...

Knock control
Detonation combustion of the fuel-air mixture due to the ignition timing being shifted too far in the direction of advancement is harmful to the engine. The...

Inductive pulse sensor
The pulse sensor is located in the direction of travel in front on the right in the engine block, immediately behind the crankshaft belt pulley. The sensor...

Camshaft Position Sensor
In combination with 16-valve engines, an additional Hall sensor is added for the above-described detonation adjustment. It serves to recognize the ignition...

Precautions when handling ignition
In the Vectra ignition system we are faced with high voltages: even on the thin control wires of the ignition system there can be voltages of up to 100 V with...

Work on the ignition system
Ignition off The ignition/injection control unit will inevitably be damaged if the engine (for example, when measuring compression pressure) will be turned by...

Troubleshooting Ignition
Anyone who wants to detect a defect in the ignition must act according to the system: A simple voltage test in the ignition system checks whether the ignition...

Checking the ignition timing
Checking the ignition timing in modern ignition systems, which are installed in Vectra models, has become almost redundant. In Vectra ignition systems without...

High voltage unit
In the ignition system, the high-voltage unit includes, in addition to the DIS ignition module – which has already been mentioned – the spark plug connectors,...

Replacing spark plugs
Maintenance work The maintenance plan calls for replacing spark plugs every 30,000 km on 8-valve models and every 60,000 km on 16-valve models. This seems to...

Buying new spark plugs
Heat rating Depending on the compression and power output, gasoline engines develop quite different temperatures in the combustion chambers. Spark plugs must...
