FLUSHING FLUID FEEDING OF AN ACTIVE PRECOMBUSTION CHAMBER FOR A TURBOCHARGED SPARK IGNITED ENGINE IN COMBINATION WITH A TURBO-COOLING

The invention relates to an internal combustion engine (1) comprising at least one cylinder (Z), wherein the at least one cylinder (Z) has a main combustion chamber (BK) for combustion of a fuel/air mixture (K/F) or a fuel/air/exhaust gas mixture (K/F/F) and a scavenged prechamber fluidly connected to the main combustion chamber (BK) via at least one transfer port, and at least one exhaust gas turbocharger (200) which has a turbine (201) for expansion of exhaust gas (F) leaving the at least one cylinder (Z) and a compressor (202) for compression of fresh air (F) to be supplied to the at least one cylinder (Z) or a fresh air/exhaust gas mixture (F/F) as pressurized charge air (F). [0002] It is provided that in a charge air line (II) downstream of the compressor (202) for supplying the combustion chamber (BK; II-1) a combustion chamber charge air line (II-1) and for supplying the prechamber (VK; II-2) a prechamber scavenging line (II-2) branching off at a take-off point (II-E', II-E", II-E''') is formed, wherein downstream of the compressor (202) of the exhaust gas turbocharger (200) upstream of the take-off point (II-E', II-E", II-E''') at least one charge air cooler (LK1, LK2) for cooling the charge air (FL) in the charge air line (II) is arranged.
