  • Patent number: 12209552
    Abstract: Piston for an internal combustion engine, preferably a gas engine comprising a pre-chamber, comprising a piston crown limiting the piston on a side facing a cylinder head when the piston is arranged inside an internal combustion engine, wherein the piston crown comprises at least one piston bowl which has a lower surface level than a radial edge region of the piston crown, wherein the piston bowl comprises a depth (d), which is defined by the distance between the radial edge region and the lower surface level of the piston bowl measured parallel to central elevation which has a height (H), wherein the height (H) of the central elevation equals the depth (d) of the piston bowl plus/minus 50%, preferably 20%, of the depth (d) of the piston bowl.

  • Patent number: 12044160
    Abstract: A pre-chamber component for an internal combustion engine includes a chamber for accommodating an air-fuel-mixture to be ignited, wherein the pre-chamber component includes a first opening into the chamber for arranging an ignition device, in particular a spark plug, and a second opening for introducing the air-fuel-mixture in the form of a mixture flow into the chamber. The pre-chamber component includes a mixture flow guiding device, which is shaped such that the mixture flow of the air-fuel-mixture in the chamber is oriented substantially transversely with respect to a longitudinal axis from the second opening of the chamber to at least a part of the chamber adjacent to the first opening and/or in the form of a turbulent flow.

  • Patent number: 11876379
    Abstract: A method including: mechanically driving a generator with an internal combustion engine, creating a generator rotary speed corresponding to a generator frequency, control of the internal combustion engine such that the generator frequency is in a tolerance range, wherein a grid frequency is within the tolerance range, detecting a phase angle difference between a current and/or a voltage generated by the generator and a grid current and/or a grid voltage, synchronizing the voltage and/or the current with the grid voltage and/or the grid current to reduce as phase angle difference (??), and electrically connecting the generator to a power supply grid, wherein at least one temporary change in an ignition timing of at least one cylinder unit of the internal combustion engine is performed to reduce the phase angle difference (??).

  • Patent number: 10161320
    Abstract: A method of operating an internal combustion engine, in particular a gas engine, comprising at least one combustion chamber to which a charge air is fed with a variable charge pressure and/or a variable amount of charge air, wherein a cylinder pressure value is ascertained from at least one measurement value of a sensor arranged in the at least one combustion chamber, wherein the cylinder pressure value is regulated by altering the charge pressure and/or by altering the amount of charge air as a setting value or values to a cylinder pressure target value, wherein the cylinder pressure target value is selected in dependence on a power of the internal combustion engine.
