tændrørets

Tændrøret, also known as the spark plug in English, is a critical component in internal combustion engines, particularly those operating on gasoline or similar fuels. Its primary function is to ignite the compressed air-fuel mixture within the combustion chamber by delivering an electric spark. This ignition process is essential for the engine’s operation, as it initiates the controlled explosion that drives the piston and generates mechanical power.

The tændrøret consists of several key parts, including an insulated electrode, a central electrode, and a metal housing that screws into the engine block. The central electrode is connected to a high-voltage wire, which receives a spark from the ignition system. When the spark jumps across the gap between the central and ground electrodes, it ignites the fuel-air mixture. The design of the tændrøret, including the electrode gap and material composition, influences combustion efficiency and engine performance.

Over time, tændrøret may degrade due to wear, corrosion, or carbon buildup, leading to misfires, reduced fuel efficiency, or engine stalling. Regular maintenance, such as periodic replacement, is recommended to ensure optimal engine function. The lifespan of a tændrøret depends on factors like engine type, driving conditions, and fuel quality, typically ranging from 30,000 to 100,000 miles (48,000 to 160,000 kilometers).

In Danish automotive terminology, "tændrøret" is commonly used alongside its English equivalent. Proper installation and selection of the correct type and size are crucial to avoid engine damage or performance issues. Mechanics often recommend using manufacturer-recommended specifications when replacing tændrøret to ensure compatibility with the vehicle’s ignition system.
