Abstract (en)
[origin: WO2017016637A1] The invention relates to a method for compensating valve drift in an internal combustion engine having a variable valve train; in said method, an actual value of the current operating state of the internal combustion engine is determined in an air expenditure map and compared to a desired value of the air expenditure map, whereupon the air expenditure map is corrected.
