Abstract
An engine controller calculates a pulsation correction value based on actuation states of an air bypass valve (ABV) and a wastegate valve (WGV) that change the shape of intake and exhaust flow passages of an exhaust turbocharger. The pulsation correction value is used to compensate for an output error of an airflow meter caused by intake pulsation. The engine controller also calculates a fuel injection amount of an injector, based on an output of the airflow meter that has been corrected based on the pulsation correction value.
