Method for controlling turbocharging of internal combustion engine of e.g. heavy commercial vehicle, involves interlocking switching turbocharger, when signaled gear ratio and signaled steering level corresponds predetermined range

摘要

The method involves driving switching compressor (121) by turbine controller (122). A switching exhaust gas turbocharger (120) is operated in addition to base exhaust gas turbocharger (110), when base turbocharger is operated in limit speed. The gear position of transmission (500) is signaled. The steering level is indicated. The switching turbocharger is interlocked to prevent activation of turbo supercharger (100) by activating charger lock switch, when signaled gear ratio corresponds predetermined gear ratio and signaled steering level corresponds predetermined steering level. An independent claim is included for a control device for internal combustion engine.
