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

摘要

The invention concerns a combustion engine (1),Comprehensive at least one cylinder (Z),where at least one cylinder (Z) has a main combustion chamber (BK) for the combustion of a fuel/air mixture (K/FL) or a fuel/air/exhaust mixture (K/FF/FA) and a flushed preheat chamber (BK) connected to the main combustion chamber (BK) via at least one overflow channel, and at least one exhaust turbocharger (200),a turbine (201) having at least one cylinder (Z) outlet gas (FA) and a compressor (202) for compression of at least one cylinder (Z) of fresh air (FF) or a fresh air/exhaust mixture (FF/FA) as compressed charge air (FL).;It is provided that in a charge air stream (II) the condenser flow rate (202) is used to supply the combustion chamber (BK); II-1) a combustion chamber charge air stream (II-1) and for supply to the antechamber (VK; II-2) one at a collection centre (II-E',II-E,II-E''') is a separate pre-chamber flushing mode (II-2) with the flow rate of the compressor (202) of the exhaust turbocharger (200) flowing on the sampling point (II-E',II-E,At least one charge air cooler (LK1, LK2) for cooling the charge air (FL) in the charge air stream (II) is fitted.
