High quality spare part in original quality. Form and function correspond to the original part.

Capacitor units are used in addition to ignition coils as a further ignition system of battery ignition. They are specially designed for powerful engines that require a powerful spark. This ensures that the fuel mixture in the cylinder is always ignited at the right time. Capacitors are better suited for this process than ignition coils.

The ignition coil only acts as a transformer because the capacitor supplies the primary circuit with a very high voltage (about 400 V).

A so-called thyristor (semiconductor component) takes over in such a 'process' the loading and unloading of the energy storage device from the capacitor. Current can only flow if the positive pole is at the anode and the negative pole is at the cathode. The passage of electricity is made possible by the 'gate'.

The necessary 'gate pulse' may, for example, be supplied by a breaker contact. Once the thyristor has been ignited, the stored voltage in the capacitor is discharged via the primary side of the ignition coil; the current decreases and the current flow is blocked by the semiconductor.

Meanwhile, the winding of the ignition coil, which is traversed by current, induces a high voltage surge within the secondary winding. This then jumps over as a spark at the electrodes of the spark plug.

Advantages:

- strong and constant sparks

- high ignition voltage reserves

- better combustion

- more efficient
