A mixture supply system with quantitative mixture control comprises a charging system connectable to an internal combustion engine, comprising a bypass and a bypass valve, and a valve train for periodically actuating an intake valve of the internal combustion engine. A valve control time of the intake valve is controllable by the valve train. The system is configured to at least partially close the bypass valve and change the valve control time for extending the valve opening duration upon increase of an engine load, to at least partially open the bypass valve during and/or after expiration of a valve train latency time, and/or to at least partially open the bypass valve and change the valve control time for decreasing the valve opening duration upon an decrease of an engine load, and to at least partially close the bypass valve during and/or after expiration of a valve train latency time.
