摘要:
A method for compensating valve drift in an internal combustion engine having a variable valve train; in the 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.
