Transient response control method and device of engine and electronic equipment

The invention relates to a transient response control method and device of an engine, electronic equipment, a storage medium and a computer program product. The method comprises the steps that after an engine of the automobile is started, the EGR rate is set to be zero, and the engine is controlled to operate under initial control parameters; when the engine operates under the initial control parameters, if the actual supercharging pressure is smaller than or equal to the supercharging threshold value of the currently started EGR system and the current table look-up EGR rate is larger than zero, the engine is controlled to operate under the pressure buildup control parameters; and when the engine operates under the pressure buildup control parameters, if the actual supercharging pressure is larger than the supercharging threshold value, the set EGR rate is controlled to be increased according to the preset step length, the engine is controlled to operate under the supercharging starting parameters, and transi
