  • Patent number: 11767801
    Abstract: An internal combustion engine (1) operating in cycles, having: a plurality of piston-cylinder units (2), wherein each piston-cylinder unit (2) of the plurality of piston-cylinder units (2) is assigned an ignition device (3) which can be controlled regarding activation and selection of an ignition timing by an engine control (4), wherein a piston-cylinder unit (2), when the ignition device (3) is activated, produces a power by combustion of a gas-air mixture, which can be transmitted as a torque to a crankshaft (5) of the internal combustion engine (1) an intake stroke (6) and an exhaust stroke (7), each coupled to the plurality of piston-cylinder units (2) a supply device (8) for supplying a gas-air mixture under a boost pressure to the intake stroke (6) a signal detection device (9) for acquiring at least one signal which represents a power demand on the internal combustion engine (1) or from which a power demand on the internal combustion engine (1) can be calculated an engine control (4) for actuating a

  • Publication number: 20220333539
    Abstract: An internal combustion engine having an engine control configured to operate in first and second operating modes. The first operating mode is configured to leave as many ignition devices deactivated per cycle in dependence on the currently present power demand. The second operating mode is configured to reduce a risk of deflagration due to unburned gas-air mixture present in an exhaust stroke. After a first number (N1) of cycles, for a second number (N2) of cycles, the second operating mode has more piston-cylinder units produce power per cycle than required for the currently present power demand. After the second number (N2) of cycles, for a third number (N3) of cycles, in dependence on a currently present power demand per cycle, the second operating mode has so many piston-cylinder units produce power that this results in a torque of the crankshaft adapted to the currently present power demand.
