structure for mounting for GDI fuel-rail

摘要

The present invention relates to a mounting structure of a DI fuel rail . Specific examples of the mounting structure 124 and the injector cup 122 is mounted structure of a DI fuel rail that contains the 120 that is coupled to the main pipe 110 , the injector cup 122 and the mounting structure 124 is being integrally connected by a bridge (126) , wherein the injector cup (122) is welded to the main pipe (110) , the mounting structure 124 and the main pipe 110 has a structure which is separate from each other . According to such a structure , and further prevent the thermal deformation due to stress concentration to avoid the stress concentration occurs , increase the fatigue strength of the displacement assembly to secure the position accuracy of the other hand the composition can improve the ease of effect .
