摘要： A control system is disclosed for operating an internal combustion engine. The control system includes a control unit configured for providing a part load mode that is optimized for slow operation of the engine at loads up to an upper part load limit in the range from 40% to 75% of a maximum engine load. The control unit is also configured for providing a high load mode for engine loads above the upper part load limit. In the part load mode, at least one inlet valve is closed at a closing angle later than in the high load mode.

摘要： A method for operating an engine is disclosed. The method may include supplying air from a primary air supply unit to an intake conduit. The method may also include supplying air to the engine from the intake conduit. The method may further include selectively supplying air from a secondary air supply unit to the intake conduit. In addition, the method may include maintaining an air fuel ratio between a first threshold value and a second threshold value during an increase in engine load increase by controlling a supply of air from the secondary supply unit to the intake conduit.
