<p>A throttle (TCV C) varies the airflow through a first line (10). An electronic control unit (ECU) operates in first and/or second modes. In the first, when the flow is increased by the throttle (TCV H) in the bypass line (20), a reduction of flow is effected in the first line (10) by throttle (TCV C), and vice versa. In the second mode, throughput increase is caused in the bypass line (20) by throttle (TCV H) and throttle (TCV C) in the first line, or a reduction of throughput is caused by the throttle (TCV H) in the bypass line (20) and the throttle (TCV C) in the first line. An independent claim is included for the corresponding method of operation.</p> |
