    • The combustion chamber formed in the upper end of the piston of the diesel engine and, more particularly, a geometrical shape of a combustion chamber of a piston. The combustion chamber includes a main combustion chamber and auxiliary chambers. The main combustion chamber has a diameter d in the range of 0.522-0.552 times the piston diameter (D). The auxiliary chamber has a tunnel like shape having a half-circle shaped cross section having a base line with a radius in the range of 0.095D-0.200D or 0.179D-0.370D from the upper end to the lower end of the side wall of the main combustion chamber of the piston cavity. The above half- circle is centered at a point where it is on a circumference whose radius is in the range of 0.105D-0.238D or 0.190d-0.446d from the centre of the main combustion chamber circle and is located in between two sprays.
    • 形成在柴油发动机的活塞的上端的燃烧室,更具体地,是活塞的燃烧室的几何形状。 燃烧室包括主燃烧室和辅助室。 主燃烧室的直径d在活塞直径(D)的0.522-0.552倍的范围内。 辅助室具有具有半圆形截面的隧道状形状,其具有从侧壁的上端到下端的半径在0.095D-0.200D或0.179D-0.370D范围内的基线 的活塞腔的主燃烧室。 上述半圆的中心位于其半径在主燃烧室圆的中心的半径在0.105D-0.238D或0.190d-0.446d范围内的圆周上,位于两个喷雾之间 。
