Method for operating internal combustion engine, involves comparing pressure variable in flow direction before actuator with another pressure variable in flow direction after actuator in predetermined operating state

摘要

The method involves comparing a pressure variable in a flow direction before an actuator (5) with another pressure variable in the flow direction after the actuator in a predetermined operating state. A correction value is formed depending on the comparison results. A pressure drop is modeled across an air channel (10) upstream of the actuator. The modeled pressure drop is corrected depending on the correction value, so a pressure value is formed depending on the corrected modeled pressure drop. An independent claim is also included for a device for operating an internal combustion engine.
