Abstract
A device with a starter-generator for internal combustion engines, the combustion engine having a centrifugal mass for stabilizing its smoothness of running, with at least one first nonpositive clutch and a flywheel generator, which can be actuated by means of an electrical energy source and is in effective connection with a selectable gearbox, the nonpositive clutch being provided between the flywheel generator, which can be actuated by means of an electrical energy source, and the combustion engine, and the flywheel generator forming the centrifugal mass of the combustion engine.
Claims8
A method for operating a device with a starter-generator for a vehicle containing an internal combustion engines, the device having a centrifugal mass for stabilizing smoothness of running of the engine, with at least one first non form engaging clutch and a flywheel generator which is actuated by means of an electrical energy source and is effectively connected with a selectable gearbox, wherein the non form engaging clutch is provided between the flywheel generator, and the combustion engine, and wherein the flywheel generator forms the centrifugal mass of the combustion engine, said method comprising the steps of:
- before the combustion engine is started, the flywheel generator is decoupled at least from the combustion engine, subsequently the flywheel generator is brought into effective connection with the energy source until the flywheel has reached a specified speed, and
- the combustion engine is then connected to the flywheel generator by means of the non-form engaging clutch.
