Definitions
- the flywheel FW is a rotor, preferably a rotor operating on the reluctance principle, a stator (ST) compared in such a way that, on the one hand, during normal operation of the internal combustion engine M in electrical generator mode, a battery B can be charged via power electronics PE and, on the other hand, when the internal combustion engine M is switched off in engine operation, the flywheel FW as the rotor of an electric motor is brought to a limit speed or held can be, which can ensure a safe start of the internal combustion engine M after coupling the flywheel clutch C1.
- part of the cylinders 1-4 of the internal combustion engine M preferably half of the cylinders 1; 2 independently of the other half 3; 4, of the cylinders with ignition or compression can be acted upon via control electronics E, that when the 'gas foot pedal A or the gearbox circuit L indicates an idling position, the one half 1; 2 of the cylinders 1-4 of the internal combustion engine M now only runs without compression and only after the two remaining ones have started Cylinder 3; 4 are switched on again via the flywheel FW which is recoupled and rotating at a limiting speed.
- a part 1; 2 of the cylinders 1-4 of the internal combustion engine M is switched off according to embodiments of the invention as a function of reaching an idle position of the transmission gearshift L or an idle position of the accelerator pedal A; the renewed connection of the previously deactivated cylinders 1 takes place in an advantageous manner automatically, in particular via a control electronics E with a time delay or speed-dependent.
- the control electronics E can also be used to actuate the flywheel clutch Cl or the normal transmission clutch C2 via assigned switches SCI or SC2.
