Zündkreis

Zündkreis is a German term that translates to "ignition circuit" in English. It refers to the entire electrical system within an internal combustion engine responsible for igniting the fuel-air mixture in the cylinders. This system typically comprises several key components.

The primary function of the Zündkreis is to generate a high-voltage spark at the correct time in each cylinder. This spark then ignites the compressed fuel and air, causing combustion and powering the engine. The timing of the spark is crucial for efficient engine operation and is usually controlled by the engine's control unit or, in older vehicles, by a mechanical distributor.

Key components of a typical Zündkreis include the battery, which provides the initial electrical power, and the ignition switch, which activates the system. The ignition coil is a vital part, transforming the low voltage from the battery into the high voltage necessary for a spark. Spark plugs, located in the cylinder head, receive this high voltage and produce the spark. In modern vehicles, electronic control units manage the ignition timing and coil activation, replacing older mechanical distributors. The Zündkreis is essential for the functioning of gasoline-powered engines.
