Tændrørsstrøm

Tændrørsstrøm is a Danish term that translates to "spark plug current" or "ignition current." It refers to the electrical current that flows through a spark plug in an internal combustion engine. This current is a critical component of the ignition system, responsible for creating a spark that ignites the fuel-air mixture in the engine's cylinder.

The process begins with the ignition coil, which transforms the vehicle's low-voltage battery power into a high-voltage surge. This high voltage is then delivered to the spark plug. When the voltage reaches a sufficient level, it overcomes the resistance between the spark plug's electrodes, creating a spark. This spark is what initiates combustion. The timing and intensity of this tændrørsstrøm are precisely controlled by the engine's management system to ensure optimal performance and efficiency.

Variations in tændrørsstrøm can indicate potential problems within the ignition system. Issues with spark plugs themselves, ignition coils, or related wiring can lead to weak or intermittent sparks, affecting engine performance, fuel economy, and emissions. Diagnosing and addressing these issues often involves checking the quality and consistency of the tændrørsstrøm.
