  "textContent": "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) for mixing of gas and air and igniting the gas-air-mixture in a pre-chamber. 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) to the ignition chamber lower part (2) 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) comprises at 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). Edges (8) at the inlet opening (6) are designed as soft edges.",
