The utility model relates to a constant current source device for an engine test bench, which is used for providing current for a calibrated object (11) and comprises an electrical protection module (1), a starting control module (2), a main control module (3), an adjusting module (4), an engine storage battery (5) and a display module (6). The input end of the electrical protection module is connected with a power input line (9), the output end of the electrical protection module is connected with the input end of the starting control module, the output end of the starting control module is connected with the input end of the main control module, and the output end of the main control module is connected with an engine storage battery and a calibrated object in series. The adjusting module can adjust the current value of the output end of the main control module; and the display module can display the current value of the output end of the main control module. According to the utilitymodel, the large-current
