Mixture-feeding system for an internal combustion engine, having quantitative mixture control

A mixture supply system for an internal combustion engine with quantitative mixture control the mixture supply system comprising:

• a charging system connectable to the internal combustion engine, comprising a bypass and a bypass valve arranged in the bypass;
• a valve train for periodically actuating an intake valve of the internal combustion engine, wherein a valve control time of the intake valve is controllable by the valve train;
• a control unit configured to control the charging system and valve train;
• wherein the mixture supply system is configured to,
• upon the increase of an engine load, the control unit at least partially closes the bypass valve and changes the valve control time for extending the valve opening duration, and during and/or after expiration of a valve train latency time, the control unit at least partially opens the bypass valve;
• and/or
• upon a reduction of the engine load, the control unit at least partially opens the bypass valve and changes the valve control time for a reduction of the valve opening duration, and at least partially closes the bypass valve during and/or after expiration of a valve train latency time.
