Precise Ignition for Petrol Engines
NGK spark plugs have been igniting since the 1930s. But sparks don’t just simply ignite. It takes a high amount of precision to create spark plugs that perform well and are extremely resistant in doing so.

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.

This video explains the electrode wear of spark plugs, especialy the difference between single spark and wasted (double) spark systems. It shows in detail why in double spark ignition systems, spark plug electrode wear is different on some cylinders.
