Abstract
An ignition device for an internal combustion engine with a charging coil, in particular disposed on a yoke core, with a starter wheel to induce a charging voltage in the charging coil by its rotation, with a first energy store which is connected to the charging coil via a rectifier, as well as with an electrical load which for its power supply, in particular during the starting process of the internal combustion engine is connected to a second energy store, wherein the second energy store is connected to the first energy store via a voltage converter. Furthermore, the invention relates to an internal combustion engine with such an ignition device and a method for its operation.
Claims17
An ignition device for an internal combustion engine, the ignition device comprising:
- a charging coil disposed on a yoke core to provide a charging voltage induced as a result of a rotational movement of a starter wheel;
- a first energy store connected via a rectifier to the charging coil;
- and
- an electrical load connected to a second energy store for energy supply during a starting operation of the internal combustion engine, the second energy store being connected via a voltage converter to the first energy store such that a first voltage at an input of the second energy store is greater than a second voltage output by the first energy store.
A method for operating an internal combustion engine with an ignition device, the method comprising:
- charging a first energy store via a charging voltage induced in a charging coil via a rectifier;
- measuring an output voltage provided by the first energy store;
- and
- charging a second energy store, connected to the first energy store via a voltage converter, as a function of the output voltage provided by the first energy store such that a first voltage at an input of the second energy store is greater than the output voltage of the first energy store.
