A control method, a control device, an electronic device and a storage medium for engine operation are provided. The method includes: obtaining a rotational speed and a temperature of an engine at a current time and determining a reference value of the control parameter of the engine based on the rotational speed and the temperature; detecting a composite operating state of the engine at the current time and determining an offset of the control parameter corresponding to each operating state in the composite operating state; adding the reference value of the control parameter and the offset of the control parameter corresponding to each operating state in the composite operating state to obtain a final value of the control parameter; and controlling the engine at the current time according to the final value of the control parameter.
