SUPPLY OF AN ACTIVE PRECHAMBER FOR TURBOCHARGED GASOLINE ENGINES WITH AN AIR EXTRACTION DOWNSTREAM OF AN EXHAUST GAS TURBOCHARGER
DRIVE
April 22, 2021
An internal combustion engine having at least one cylinder that has a main combustion chamber for burning a fuel/air mixture or a fuel/air/exhaust gas mixture and has a flushed prechamber connected to the main combustion chamber via at least one overflow duct on the fluid side. At least one exhaust gas turbocharger is provided that has a turbine for the expansion of the at exhaust gas leaving the at least one cylinder and a compressor for compressing fresh air or a fresh air/exhaust gas mixture to be supplied to the at least one cylinder as compressed charge-air. In a charge-air line downstream of the compressor, an extraction point is formed from which a flushing line branches off, via which a partial amount of charge-air of the compressed charge-air for flushing the at least one prechamber can be extracted.
