Engine control method and device, equipment, storage medium and product

The invention discloses an engine control method, device and equipment, a storage medium and a product. The method comprises the steps that the number of sequential superchargers which work is judged; and whether the supercharger rotating speed of the sequential superchargers is in a hysteresis range or not is determined, and when the supercharger rotating speed of the sequential superchargers is in the hysteresis range, the rail pressure and the fuel injection advance angle of the engine are determined according to the number of the working sequential superchargers. According to the method, the number of the sequential superchargers in work is judged, when the rotating speed of the sequential superchargers is in a hysteresis interval, the fuel injection advance angle of the rail pressure of the engine is determined according to the number of the sequential superchargers in work, and in the same hysteresis interval, when the number of the sequential superchargers in work is different, the fuel injection advan
