F02B23/06 - CPC Classification

Classification description:

Other engines characterised by special shape or construction of combustion chambers to improve operation with compression ignition the combustion space being arranged in working piston

Sub-classes:

F02B2023/0615 » {the combustion space having a volume defined by revolution around an axis inclined relative to the cylinder axis} 3
F02B23/0603 » {at least part of the interior volume or the wall of the combustion space being made of material different from the surrounding piston part, e.g. combustion space formed within a ceramic part fixed to a metal piston head} 17
F02B23/0618 » {having in-cylinder means to influence the charge motion} 6
F02B23/0633 » {the combustion space being almost completely enclosed in the piston, i.e. having a small inlet in comparison to its volume} 15
F02B23/0636 » {the combustion space having a substantially flat and horizontal bottom} 9
F02B23/0642 » {the depth of the combustion space being much smaller than the diameter of the piston, e.g. the depth being in the order of one tenth of the diameter} 3
F02B23/0645 » {Details related to the fuel injector or the fuel spray} 17
F02B23/0672 » {Omega-piston bowl, i.e. the combustion space having a central projection pointing towards the cylinder head and the surrounding wall being inclined towards the cylinder center axis } 147
F02B23/0675 » {the combustion space being sunstantially spherical, hemispherical, ellipsoid or parabolic} 23
F02B23/0678 » {Unconventional, complex or non-rotationally symmetrical shapes of the combustion space, e.g. flower like, having special shapes related to the orientation of the fuel spray jets} 33
F02B23/0696 » {W-piston bowl, i.e. the combustion space having a central projection pointing towards the cylinder head and the surrounding wall being inclined towards the cylinder wall} 108
