Magnetzündsystems

Magnetzündsysteme, often referred to as magneto ignition systems, are a type of ignition system used primarily in internal combustion engines, particularly those found in motorcycles, small aircraft, and older vehicles. Their defining characteristic is the use of a magneto generator to produce the high voltage required to ignite the fuel-air mixture in the combustion chamber. A magneto is a self-contained electrical generator that converts mechanical energy into electrical energy. It consists of a rotating magnet that passes over stationary coils of wire. As the magnet spins, its changing magnetic field induces a current in the coils. This induced current is then amplified and timed to produce a spark at the spark plug.

Unlike battery-based ignition systems that rely on a battery and an ignition coil, magneto systems are independent of the vehicle's electrical system. This makes them very reliable, as they can continue to operate even if the battery fails or is absent. The mechanical energy for the magneto is typically supplied by the engine itself, often through a drive mechanism connected to the crankshaft or camshaft. The timing of the spark is usually controlled by a breaker point system or, in more modern designs, by electronic components integrated within the magneto unit. The simplicity and robustness of magneto ignition systems have contributed to their long-standing use in applications where reliability and self-sufficiency are paramount.
