The invention discloses a method for calibrating the ignition advance angle of an engine, bench test equipment for calibrating the ignition advance angle of the engine and an engine control system, and the method comprises the steps: transmitting a target working condition instruction of the engine, so as to enable the engine to operate in a target working condition state; obtaining a calibration reference parameter obtained based on a combustion pressure signal in the operation of the engine; and the target ignition advance angle of the engine corresponding to the target working condition state is determined according to the calibration reference parameters. According to the method for calibrating the ignition advance angle of the engine, the target ignition advance angle of the corresponding target working condition state of the engine is determined by calibrating the reference parameters, the method is not influenced by human factors, the calibration process is more objective, and the accuracy and the cali
