ADAPTING FLOW DYNAMICS FOR INTERNAL COMBUSTION ENGINES

An internal combustion engine (1) for operation on at least partly gaseous fuel under adjusted flow dynamics comprises an engine block cylinder unit section (3) providing a main combustion chamber (5), and a cylinder head (11) covering the main combustion chamber (5). The cylinder head (11) comprises an intake channel (13) for providing a charge air-gaseous fuel mixture through an intake opening (13A) into the main combustion chamber (5) and an ignition source (31) for igniting the charge air-gaseous fuel mixture within the main combustion chamber (5). The ignition source (31) is configured for providing ignition jets (35) into the main combustion chamber (5) along injection directions (V J ). The internal combustion engine (1) is further configured to generate a flow system (F) of the charge air-gaseous fuel mixture within the main combustion chamber (5) such that the flow system (F) includes at least one counter flow section (C) that at least partly spatially overlaps with a respective one of the ignition jets (35) and has a flow direction (V F ) directed at least partly against the respective injection direction (V J ). Thereby, the amount of the ignited charge air-gaseous fuel mixture may be increased.
