Internal combustion engine operating method for use in motor vehicle, involves assigning characteristics of filtered model values of exhaust gas back pressure to characteristics of actual values of pressure

摘要

The method involves assigning characteristics of filtered model values (EGBP-MDL-FIL) of exhaust gas back pressure to characteristics of actual values of the exhaust gas back pressure during adjusting and/or real time adjustment of a valve stroke. The characteristics of the filtered model values of the exhaust gas back pressure are determined by a low-pass filter. Actual values (EGBP-AV) and/or actual model values (EGBP-MDL-1, EGBP-MDL-2) of the exact gas back pressure are provided as target values for the low-pass filter. An independent claim is also included for a device for operating an internal combustion engine.
