摩托车在出厂时为了保证技术指标和动力性能,均配有相应的主量孔喷嘴。其主量孔的大小与车的油耗有着直接的关系。使用中发现摩托车很少在极限状态下运行,特别是在城市行车,也就无需使用太大的主量孔喷嘴。笔者的南方125-2B车出厂时所配主喷嘴量孔直径为1.15mm,短途使用100km体积油耗4L,改造后主量孔直径为0.86mm,100km体积油耗降为2.5L。 具体改造方法如下:拆下化油器主喷嘴。用一只粗细合适的手工缝纫针插入主量孔,并用千分尺
Motorcycles at the factory in order to ensure technical indicators and dynamic performance, are equipped with the corresponding main orifice nozzle. The size of the main hole and the car has a direct relationship between fuel consumption. In use, it is found that motorcycles are rarely operated at extreme conditions, especially when driving in the city, and there is no need to use a large main orifice nozzle. The author’s southern 125-2B car with the main nozzle orifice diameter of 1.15mm, short-distance use 100km volume fuel consumption 4L, after the transformation of the main hole diameter of 0.86mm, 100km volume fuel consumption dropped to 2.5L. Specific methods of transformation are as follows: Remove the main nozzle carburetor. Insert a hand sewing needle of the correct thickness into the main hole and use a micrometer
