Gyújtógyertyárak

Gyújtógyertyák, often translated as spark plugs, are critical components in internal combustion engines. Their primary function is to ignite the air-fuel mixture within the combustion chamber, initiating the power stroke. This ignition is achieved by creating a high-voltage electrical spark that jumps across a gap between two electrodes.

The design of a spark plug typically includes a central electrode and a ground electrode, insulated from each other by a ceramic material. A metal shell connects to the engine block, providing the ground path. When the ignition system delivers a high-voltage pulse, it overcomes the resistance of the air-fuel mixture between the electrodes, causing a spark.

The performance and longevity of a spark plug depend on several factors, including the materials used, the gap setting, and the operating conditions of the engine. Different types of spark plugs exist, such as those made of copper, platinum, and iridium, each offering varying levels of durability and performance characteristics. Proper maintenance and replacement of spark plugs are essential for optimal engine efficiency, fuel economy, and reduced emissions. Signs of worn or fouled spark plugs can include misfires, rough idling, and decreased power.
