Abstract

An engine controller, an engine control method, and memory medium are provided. A second calculation process calculates an intake air amount without using a detection result of an air flow meter. The determination process determines that intake air pulsation is great if it is confirmed that a difference between an average flow rate and a minimum flow rate is great. The average flow rate is an average value of an intake air flow rate within a period of the intake air pulsation. The minimum flow rate is a minimum value of the intake air flow rate within the period. When it is determined that the intake air pulsation is great, a calculation method switching process selects a calculated value of the intake air amount that is obtained by the second calculation process.
