摘要

The invention relates to an internal combustion engine, in particular a large two-stroke diesel engine, comprising at least one combustion chamber (2) delimited by a cylinder (1) and a piston (3) interacting with a crankshaft, said combustion chamber comprising at least one combustion gas outlet (20; 120; 320; 420), which is formed between a valve disk (8; 108; 308) of an exhaust valve (9; 109; 309) and an associated disk seat, and at least one charge air inlet (4). The exhaust valve (9; 109; 309) can be actuated between an open position and a closed position. The combustion gas outlet (20; 120; 320; 420) is connected to at least one outlet channel (11) and to at least one combustion gas draw-off duct (18; 118a, 118b; 318, 318a; 418, 418a), for example in order to recirculate part of the combustion gas generated during combustion to the charge air inlet (4). The invention further relates to an exhaust valve (9; 109; 309) and to a cylinder head for such an internal combustion engine. The invention is characterized by a throttle device (10; 110; 310) which is fastened to the exhaust valve (9; 109; 309) or integrally molded as part of the exhaust valve (9; 109; 309) and by means of which the combustion gas is drawn off in a predetermined way. The invention further relates to a method for producing an internal combustion engine, to a method for operating an internal combustion engine, and to a use for an internal combustion engine.
