The invention relates to the technical field of engine accessories, in particular to an automatic switching dual-fuel outboard engine carburetor, an oil cup is connected with a kerosene fuel pump and a gasoline fuel pump, and a driving assembly has a first state in which a first negative pressure channel is communicated and a second negative pressure channel is blocked; the driving assembly further has a second state for blocking the first negative pressure channel and communicating with the second negative pressure channel, and further has a third state for communicating the first negative pressure channel and the second negative pressure channel at the same time, and when the driving assembly is in the first state, the oil cup conveys oil only through the gasoline fuel pump. When the driving assembly is in the second state, the oil cup conveys oil only through the kerosene fuel pump, and when the driving assembly is in the third state, the oil cup conveys oil through the gasoline fuel pump and the kerosene fuel pump at the same time. And flexible replacement and utilization of different fuels are realized.

    本发明涉及发动机配件技术领域,尤其是涉及一种自动切换双燃料舷外机化油器,所述油杯连接有煤油燃油泵和汽油燃油泵,所述驱动组件具有连通第一负压通道以及阻断第二负压通道的第一状态,所述驱动组件还具有阻断第一负压通道以及连通第二负压通道的第二状态,所述驱动组件还具有同时连通第一负压通道和第二负压通道的第三状态,当驱动组件处于第一状态时所述油杯仅通过汽油燃油泵输油,当驱动组件处于第二状态时所述油杯仅通过煤油燃油泵输油,当驱动组件处于第三状态时所述油杯通过汽油燃油泵和煤油燃油泵同时输油,本发明具有精简的燃料切换结构,能够对两种燃料进行稳定且快速的自动切换,实现了不同燃料间的灵活替换和利用。
