KontaktlosZündsystemen

KontaktlosZündsystemen, also known as contactless ignition systems, are an advancement over traditional breaker point ignition systems. In these systems, the physical contact breaker points are replaced by an electronic trigger mechanism. This eliminates the need for mechanical adjustment of the points and their eventual wear, leading to greater reliability and reduced maintenance.

The core principle of a kontaktlosZündsystem involves a sensor that detects the position of the engine's crankshaft or camshaft. This sensor, often a Hall effect sensor or an inductive pickup, generates an electrical signal when a specific position is reached. This signal is then processed by an electronic control unit (ECU) or an ignition module.

Upon receiving the signal from the sensor, the ECU or ignition module determines the precise moment to fire the ignition coil. This results in a high-voltage spark at the spark plug, igniting the fuel-air mixture. Because the trigger is electronic and not mechanical, the timing of the spark is more accurate and consistent across the engine's operating range.

Key advantages of kontaktlosZündsystemen include improved fuel efficiency, easier starting, smoother engine running, and a longer lifespan for ignition components. They are less susceptible to issues caused by moisture, dirt, and vibration, which can affect mechanical breaker points. The absence of mechanical wear also means that the system maintains its timing accuracy over time without requiring periodic adjustments. Modern vehicles almost exclusively use electronic ignition systems, with kontaktlosZündsystemen being a common and foundational technology within this category.
