摘要

METHOD FOR LOADING A LARGE-WASHED TWO-LONG DIESEL LARGE ENGINE CYLINDER AND ALSO A LONG-WASHED TWO-TIME LARGE DIESEL ENGINE. The present invention relates to a method for loading a cylinder (2) of a large longitudinally flushed two-stroke diesel engine (1) with charge air (3), in which flushing slots (5) are provided in an inlet region (4) of the cylinder (2) for the supply air supply (3), and an outlet valve (8) is provided in a cylinder cover (6) of the cylinder (2) for discharge of a flue gas (7). In the method of the present invention, fresh air (9) available at ambient pressure (P ~ 0 ~) is drawn in by an exhaust gas turbocharger (10) and is fed to cylinder (2) as a charge air. (3) at a predetermined charge air pressure (P ~ L ~) through the wash slots (5). According to the present invention, a temperature sensor (12,13) is provided for the measurement of a charge air induction temperature (T ~ 0 ~) and / or for the measurement of the charge air temperature (T ~ ~ L ~) (3), with the induction temperature (T ~ 0 ~) and / or the charge air temperature being measured in operating state with the temperature sensor (12, 13). An amount of charge air (3) with which the cylinder (2) is charged is determined from the induction temperature (To) and / or from the charge air temperature (T ~ L ~). The determined amount of charge air (3) becomes available to cylinder (2) by controlling the outlet valve (8). The present invention further relates to a longitudinally washed large two-stroke diesel engine for carrying out the method.
