Spark Plug Requirements

As the main source of power in any petrol engine, a spark plug performs an essential function: It is responsible for igniting the air-fuel mixture in the combustion chamber of
petrol engines. This combustion process creates power, which sets the vehicle in motion. To make sure this process runs smoothly, the spark delivered by the spark plug must ignite just before the piston reaches its highest point and the compression is at its greatest.

To make sure the combustion process runs smoothly, the spark delivered by the spark plug must ignite just before the piston reaches its highest point and the compression is at its greatest. 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 harmful emissions.
