The invention aims to provide a multi-source energy cooperative ultra-low carbon ammonia fuel hybrid power system, which comprises a liquid ammonia-diesel oil dual-fuel engine, a motor, a gear box and a propeller, the liquid ammonia-diesel oil dual-fuel engine and the motor are respectively connected with the gear box, the gear box is connected with the propeller, and the propeller is connected with the motor. The liquid ammonia-diesel oil dual-fuel engine comprises an ammonia fuel common-rail pipe, a diesel oil common-rail pipe and an air cylinder, the air cylinder is connected with an air inlet channel and an exhaust pipe, an ammonia fuel injector and a diesel oil injector are installed in the air cylinder, the ammonia fuel injector is connected with the ammonia fuel common-rail pipe, and the diesel oil injector is connected with the diesel oil common-rail pipe. The system always works in a high-efficiency area, the heat efficiency of the system is improved by introducing the SCR aftertreatment system and the exhaust gas turbocharger, meanwhile, tail gas treatment of the system is achieved, the total emission amount of nitric oxide of the engine is reduced through the hybrid power system, the workload of the SCR system is relieved, the nitric oxide is fully absorbed, and the service life of the system is prolonged. And zero pollution and zero emission of the whole system are realized.
