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.

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.

Abstract: An internal combustion engine includes transfer passages between a pre-chamber and a main combustion chamber, and a control unit configured to control a pre-chamber supply system coupled to the pre-chamber and a main combustion chamber supply system coupled to the main combustion chamber, wherein the control unit is configured to control the pre-chamber supply system such that a supply volume exceeds a volume of the pre-chamber and that a surplus of the supply volume is communicated to the main combustion chamber, such as during a transient operating condition.

Abstract: A reciprocating engine and a method for regulating a reciprocating engine, in which a combustion chamber temperature ?-BRT in one or more cylinders is made available, wherein the combustion chamber temperature ?-BRT in the respective cylinder is measured, and the ignition point is individually regulated in one or more cylinders in such a way that an upward or downward deviation of the combustion chamber temperature ?-BRT from a predefined desired value S is minimal.
