tændingssystemets

Tændingssystemet, or ignition system, is a crucial component in internal combustion engines, responsible for initiating the combustion process. Its primary function is to generate a high-voltage electrical spark at the precise moment required to ignite the fuel-air mixture within the engine's cylinders. This ignition timing is critical for optimal engine performance, efficiency, and emissions control.

The fundamental components of a traditional tændingssystem include a battery, an ignition coil, a distributor, spark plugs, and associated wiring. The battery provides the initial low-voltage electrical power. The ignition coil acts as a step-up transformer, converting this low voltage into the high voltage necessary for a spark. The distributor, in older systems, directs this high voltage to the correct spark plug at the appropriate time. Modern vehicles often utilize electronic ignition systems, which replace the mechanical distributor with solid-state electronic controls for more precise timing and improved reliability.

Spark plugs are the final delivery point of the high-voltage charge. They are designed with a gap between two electrodes, and when the voltage across this gap exceeds a certain threshold, it jumps, creating a spark. This spark ignites the compressed fuel-air mixture, causing the explosion that drives the piston. The timing of this spark is managed by the engine control unit (ECU) in modern vehicles, taking into account various engine parameters to optimize performance. Variations in ignition systems exist, but their core purpose remains the same: to reliably ignite the combustion event.
