F02B23/0687 - 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; 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 Multiple bowls in the piston, e.g. one bowl per fuel spray jet
