The spark plug plays an important role in petrol engines. It is responsible for ignition of the fuel-air mixture. The quality of this ignition influences several factors which are of great importance for both the driving operation and the environment. This includes smooth running, performance and efficiency of the engine as well as the harmful emissions.
When one considers that a spark plug must ignite between 500 and 3500 times per minute, it becomes clear how great the contribution of spark plug technology is for the adherence to current emissions standards and to the reduction of fuel consumption.
- The igniting spark: The spark plug is responsible for ignition of the fuel-air mixture.
- Design of a spark plug: A spark plug consists of a few components which are perfectly matched to one another.
- Installation position of the spark plug: The spark plug is screwed into the cylinder head.
- Distribution of the ignition spark: : A mechanical ignition distributor ensures that the voltage reaches the individual cylinders and spark plugs successively - and at the right time.
