The invention discloses a method for calculating the in-cylinder air intake flow of an engine. The method comprises the following steps: the theoretical in-cylinder air intake flow of the engine is obtained; the backflow air flow in a backflow pipeline of the engine is obtained; and the actual in-cylinder air intake flow of the engine is calculated according to the theoretical in-cylinder air intake flow and the backflow air flow. The invention further discloses a device for calculating the in-cylinder air intake flow of the engine, and a readable storage medium. The actual in-cylinder air intake flow of the engine is calculated through the theoretical in-cylinder air intake flow and the backflow air flow, the accuracy of the calculated in-cylinder air intake flow can be guaranteed, and therefore the in-cylinder air intake flow of the engine can be effectively controlled. 本发明公开了一种发动机的缸内进气量计算方法，所述方法包括以下步骤：获取所述发动机的理论缸内进气量；获取所述发动机的回流管路内的回流气量；根据所述理论缸内进气量和所述回流气量，计算所述发动机的实际缸内进气量。本发明还公开了一种发动机的缸内进气量计算装置及可读存储介质。通过理论缸内
