  • Patent number: 10287969
    Abstract: An internal combustion engine including at least one combustion chamber having a main chamber and a prechamber, wherein the prechamber is in fluid connection with the main chamber via at least one bore. The at least one combustion chamber is connected to a charging path for the supply of a combustion air-fuel mixture into the combustion chamber via the charging path. A fuel intermixing region is arranged in a section of the charging path separately assigned to the combustion chamber, which fuel intermixing region is in fluid connection with the charging path on one side and with a fuel line on the other side for the supply of fuel into the fuel intermixing region via a controllable fuel valve. The internal combustion engine wherein the prechamber and the fuel intermixing region are in fluid connection with one another via a check valve.

  • Publication number: 20180223773
    Abstract: A power generating assembly including an internal combustion engine and a combustion gas supply connected to the internal combustion engine in order to supply combustion gas. The combustion gas supply has an at least double-walled line at least in the region of the internal combustion engine, the line having an inner line volume for combustion gas and an outer line volume. The outer line volume is fluidically connected to an inert gas supply. The power generating assembly also includes a combustion gas pressure adjusting device that adjusts a combustion gas pressure in the inner line volume, and an inert gas pressure adjusting device that adjusts an inert gas pressure in the outer line volume. The combustion gas pressure adjusting device and the inert gas pressure adjusting device select the inert gas pressure and the combustion gas pressure such that the inert gas pressure is higher than the combustion gas pressure.
