Definitions

  • the invention relates to a method for operating a valve-controlled internal combustion engine coupled to a starter-generator generator without a clutch, and an internal combustion engine for carrying out the method according to claim 1.
  • Such a starter generator thus takes on the one hand the function of the usual direct starting via a starter as well as the function of an alternator for charging the battery and, by utilizing the kinetic energy stored in it, in turn allows a reduction in emissions and fuel consumption due to the possibility of being switched off of the internal combustion engine in the intermediate operating phases without any effort.
  • EP 0 555 805 AI discloses a motorcycle drive that can be started by a normal starter, the compression of which is reduced by a centrifugal governor each time the engine is started and is fully reproducible from a minimum speed. The ignition is switched on from the start; flywheel support is not addressed.
  • the size and weight of the starter generator are to be further reduced with a simplified structure, and a particularly compact starter generator drive is to be created.
  • the starter generator is combined with a valve-controllable internal combustion engine which is available per se and is intended for installation in a motor vehicle, and when the internal combustion engine is coupled directly, without automatic flywheel system and Schwungnutzkup, the valves are connected by means of a starter generator - in an advantageous manner already existing - valve control can be adjusted in an at least reduced compression, expediently reduced to zero and the ignition of the internal combustion engine switched off;
  • the flywheel mass of the rotor of the starter-generator is expediently designed only with regard to a guaranteed concentricity of the internal combustion engine. If the speed falls below the minimum, safe combustion engine operation with further controlled ignition is guaranteed.
  • FIG. 1 shows a first embodiment with a solid line contour and a second embodiment example with a dashed line contour of a starter generator 2 or 3 that can be coupled to a valve-controllable internal combustion engine 1.
  • the starter generator 2 or 3 is coupled to the crankshaft 1.1 of the valve-controllable internal combustion engine 1 without a separate automatic flywheel automatic and flywheel intermediate clutch.
  • the rotor 2.1 of the starter generator 2 is arranged directly on the crankshaft 1.1 of the valve-controllable internal combustion engine 1 such that the rotor shaft 2.11 of the starter generator 2 simultaneously forms the crankshaft 1.1 of the valve-controllable internal combustion engine 1 .
  • the stator 2.2 of the starter generator 2 is held on a flange of the valve-controllable internal combustion engine 1.
  • the internal combustion engine 1 and the starter generator 2 are driven via a transmission clutch 4 and a downstream transmission 5 to the wheel drive of a motor vehicle, not shown here;
  • a separate gearbox clutch and a separate gearbox an automatic circuit with an integrated clutch can also be used.
  • a starter generator 3 is arranged on the outer circumference of the internal combustion engine 1 in such a way that its rotor shaft 3.1 runs parallel to the crankshaft 1.1 of the internal combustion engine 1.
  • a transmission 9 with two intermeshing gearwheels 9.1 and 9.2, respectively is provided in the sense of a translation, again without automatic flywheel use and a flywheel intermediate clutch;
  • meshing gear wheels for example, a toothed belt transmission known per se or the like can also occur.
  • valve-controllable internal combustion engine 1 Before the valve-controllable internal combustion engine 1 is started or accelerated, its valves are adjusted by a control unit 1.3 via a valve actuator 1.2 so that there is practically no compression in the internal combustion engine 1.
  • the starter-generator 2 can then accelerate the crankshaft 1.1 of the internal combustion engine 1 with low power in motor operation with relatively low power when fed from a battery 8 via a frequency converter 7.
  • the starter-generator only has to overcome the moment of inertia of the internal combustion engine 1 and its friction.
  • the internal combustion engine when the internal combustion engine is started up, all of its cylinders are operated with minimal or totally reduced compression and accordingly with the ignition or injection or mixture preparation switched off; the adjustment of the valves themselves is carried out in a manner known per se, in particular by direct corresponding valve lift control or by a corresponding change in the control angle between the camshaft and crankshaft.
  • the valves of the internal combustion engine 1 are adjusted via the control unit 1.3 and the valve actuator 1.2 so that the operational combustion process can now be initiated after the ignition process of the internal combustion engine 1 is switched on, the flywheel energy previously applied by the starter-generator in its engine operation helping to start and accelerate the internal combustion engine 1 for a short time.
  • a valve-controllable internal combustion engine 1 is provided with a motor which is known per se and is intended for driving a motor vehicle, with a variable valve lift or camshaft control.

Abstract

Pour simplifier la conception et réduire le poids d'un démarreur-alternateur (2) destiné au démarrage d'un moteur à combustion interne (1), les soupapes dudit moteur à combustion interne (1), qui est commandé par soupapes, sont déplacées de façon à créer une compression minimale pendant l'accélération initiale produite par le démarreur-alternateur (2) et tandis que l'allumage du moteur à combustion interne (1) est encore à l'arrêt.
