摘要：
There is described a method of controlling air intake flow of an internal combustion engine (1), the method including the steps of calculating a reference airflow (AREF) as the sum of a feed-forward contribution (AFF), calculated as a function of the reference air/fuel ratio ((A/F)REF) to be obtained in the combustion chamber, and a feed-back contribution (AFB), calculated as a function of the oxygen concentration (% O2) of the exhaust gas; and closed-loop controlling the air intake flow of the engine so that it equals the reference airflow (AREF).
