description	The invention relates to a pre-chamber bottom section, a pre-chamber, a cylinder device, and a relative method. A pre-chamber bottom section (1) for a pre-chamber of a cylinder of an internal combustion engine comprises an ignition chamber lower part (2) with a vertical axis (3). The pre-chamber bottom section further comprises a duct (4) for connecting the ignition chamber lower part (2) with a main combustion chamber of the cylinder, wherein the duct (4) comprises at least one duct longitudinal axis (5). An inlet opening (6) of the duct (4) is formed such that the vertical axis (3) has an inclination (A) relative to the duct longitudinal axis (5), and the inlet opening (6) is arranged eccentrically, such that a tumble flow motion is formable in an ignition chamber. The duct (4) comprisesat least one, preferably exactly one, outlet opening (7) which is arranged such that a gas-air mixture beam or gas-air mixture beams are formable being asymmetrically distributed relative to the vertical axis (3).
