    • 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.
    • 本发明涉及一种用于预混合燃烧(Otto循环)的内燃机的气缸(1)的预腔室装置,该预制室装置包括用于混合和点燃燃料的第一室(7)和 第二室(8)具有基本上较小的体积,用于在第一室(7)和气缸(1)的主燃烧室(4)之间连通,第一室(7)设有先导喷射装置(9) 基本上与第二室(8)相对的室顶部。 第一腔室(7)具有大致椭圆形的形状,在腔室顶部和第二腔室(8)之间具有弯曲的壁。 第二室(8)相对于第一室(7)不对称地定位,以便在第一室(7)中为从主燃烧室(4)压缩的气体燃料提供滚筒流动(A),以及 由第一腔室(7)的弯曲壁引导并朝向要点燃的引燃喷射装置(9)的燃料喷射。
