在发动机起动之后,蓄电池的电力便不再有问地方需要消耗了。因此,把用于控制预热塞电流的电阻器件装在燃油滤清器上,以防止燃油粘度增高时析出石腊,从而避免燃油滤清器的堵塞。 燃油滤清器14的外体15底部为封闭的圆筒形,过滤器16插入其中。当过滤器16座落在外体15形成的支持件15a上时,上部被固定在外体15上的盖子17压住。盖子17开有进油通道17a。流过止回阀17c的燃油,借助上部的第一燃油室17b,下部的第二燃油室17d,外体15的通油孔15b,流入过滤器16内。滤过的燃油通过过滤器定位部17f上的出油道17e流出。
After the engine starts, the battery power is no longer asked where you need to consume. Therefore, the resistor means for controlling the glow plug current is mounted on the fuel filter to prevent paraffin from precipitating as the viscosity of the fuel increases, thereby avoiding clogging of the fuel filter. The bottom of the outer body 15 of the fuel filter 14 is of a closed cylindrical shape with the filter 16 inserted therein. When the filter 16 is seated on the support member 15a formed by the outer body 15, the upper portion is pressed by the cover 17 fixed to the outer body 15. As shown in FIG. The lid 17 has an oil inlet passage 17a. The fuel flowing through the check valve 17 c flows into the filter 16 through the upper first fuel chamber 17 b, the lower second fuel chamber 17 d, and the oil passage 15 b of the outer body 15. The filtered fuel flows out through the oil outlet 17e in the filter positioning portion 17f.
