The invention discloses an internal combustion traction system, which comprises a diesel engine power device, a super capacitor and a control module, wherein the diesel engine power device is used foroutputting direct current to supply power to a converter; the super capacitor is used for outputting direct current to supply power to the converter when a traction motor executes a traction mode, and is also used for storing regenerative braking energy when the traction motor executes a braking mode; the converter is used for converting direct current output by the diesel engine power device andthe super capacitor into alternating current to supply power to corresponding loads; the control module is used for controlling the traction motor to execute the traction mode when receiving a traction instruction, and is also used for controlling the traction motor to execute the braking mode when receiving a braking instruction. In the invention, the converter is powered by two path of parallelinput, the electric energy output by power generation of the diesel engine through a rectifier is used as the main power input, and the energy stored by the super capacitor is used as the secondary power input. Compared with the prior art, the regenerative braking energy is stored by the super capacitor, the power is provided for the converter, and the energy is saved.
