摘要： The invention relates to a pre-chamber arrangement for a cylinder (1) of an internal combustion engine fitted for premixed combustion (Otto cycle), the pre- chamber arrangement including a first chamber (7) for mixing and igniting of the fuel and a second chamber (8) of substantially smaller volume for communication between the first chamber (7) and the main combustion chamber (4) of the cylinder (1), the first chamber (7) being provided with pilot injection means (9) and having a chamber top substantially opposite to the second chamber (8). The first chamber (7) has substantially oval shape with curved walls between the chamber top and the second chamber (8). The second chamber (8) is asymmetrically positioned with regard to the first chamber (7) so as to provide a tumble flow motion (A) in the first chamber (7) for the gaseous fuel pressed from the main combustion chamber (4) and guided by curved wall of the first chamber (7) towards and past the fuel of pilot injection means (9) to be ignited.
