Operating internal combustion engines

摘要

The present disclosure relates to a control system (1) for operating an internal combustion engine. A part load mode which is optimized for slow steaming for an engine load up to an upper part load limit in the range from 40 % to 75% of a maximum engine load is provided. Additionally, a high load mode for an engine load above the upper part load limit is provided. In part load mode, at least one inlet valve (4) is closed at a closing angle later than in the high load mode.
