The invention discloses a range extender system of a methanol engine in the technical field of hybrid power. The range extender system comprises the methanol engine, a generator, an engine cooling water tank, an engine controller, a generator controller and a range extender controller, a methanol engine flywheel is integrated with a generator rotor; a methanol engine flywheel shell is integrated with a generator stator; the engine cooling water tank is arranged on the heat dissipation side of the methanol engine and connected with the methanol engine through a rubber pipeline. The methanol engine and the generator share the same cooling system; the range extender controller is connected with the engine controller and the generator controller through wire harnesses. The methanol fuel is reasonable in design, methanol is used as a main fuel, methanol contains oxygen to promote sufficient combustion of the fuel, heat efficiency of an engine is improved, emission of harmful substances of the engine can be obviously reduced, and the methanol is not prone to volatility so that automobile safety can be improved; meanwhile, the generator has the advantages of being small in size, light in weight and high in power generation efficiency, and the overall efficiency of the range extender system can be further improved.

    一种混合动力技术领域的甲醇发动机的增程器系统,包括甲醇发动机、发电机、发动机冷却水箱、发动机控制器、发电机控制器、增程器控制器;甲醇发动机飞轮集成发电机转子,甲醇发动机飞轮壳集成发电机定子;发动机冷却水箱布置在甲醇发动机散热一侧,通过橡胶管路与甲醇发动机相连;甲醇发动机与发电机共用同一套冷却系统;增程器控制器通过线束与发动机控制器、发电机控制器相连接。本发明设计合理,以甲醇作为主燃料,由于甲醇自身含氧可以促进燃料充分燃烧,提高发动机的热效率,能够明显降低发动机有害物质的排放,其不易挥发性可以提高汽车安全性;同时发电机具有体积小、重量轻、发电效率高的优点,可以使增程器系统整体效率进一步提高。
