10 Leading Spark Plug Manufacturers in the world

10 Leading Spark Plug Manufacturers in the world

Introduction to Spark Plugs

A spark plug is a crucial component in an internal combustion engine. Its primary function is to ignite the air - fuel mixture within the engine's combustion chamber. When an electrical current passes through the spark plug, it creates a spark at the electrode gap. This spark is powerful enough to ignite the compressed air - fuel mixture, which then releases energy to drive the engine's pistons and ultimately power the vehicle or machinery.

 

The performance of a spark plug can significantly impact an engine's efficiency, power output, and emissions. Factors such as the material of the electrodes, the design of the spark plug, and its heat range all play important roles in determining how well it functions. High - quality spark plugs can improve fuel economy, reduce engine misfires, and enhance overall engine performance.

 

Now, let's take a look at the 10 leading spark plug manufacturers in the world:
