摘要： A coke scraper ring (18) for placement proximate to a top dead center (24) in a cylinder (13) of an internal combustion engine (10) is disclosed. The coke scraper ring (18) includes an inner surface (34) configured to face a fuel-air mixture. A plurality of turbulators (20) are formed on the inner surface (34) for inducing turbulence in the fuel-air mixture.

摘要： A pre-combustion chamber unit (57) that has a hollow shape elongated along a longitudinal axis (53) for providing a pre-combustion chamber (59) comprises a pre-combustion chamber wall (67) delimiting the pre-combustion chamber (59). The pre-combustion chamber wall (67) comprises a main section (67A) at least partly surrounding an ignition portion (59A) of the pre-combustion chamber (59), a tip section (67B) forming a pre-combustion chamber tip section (63) of the pre-combustion chamber assembly (50), and a seal section (67C) in-between the tip section (67B) and the main section (67A) for providing a seal region (73) in the mounted state. The main section (67A) comprises an external fluid guiding surface (81A) circumferentially extending around the longitudinal axis (53) and being curved along and towards the longitudinal axis (53) for smoothly redirecting a cooling fluid. Thereby the cooling may be improved.
