AI Technical Summary

Technical Problem

Existing FTIV valves have a small ventilation area and high flow resistance. The solenoid valve wiring harness is prone to detachment and the ends are easily pulled, affecting the working efficiency of the fuel system and vehicle performance.

Method used

The design of the right-angle ventilation cavity structure increases the ventilation area. The use of coaxial positioning and locking components and end support components ensures precise docking between the wire harness plug and the socket. The linkage design of the compression spring and the synchronous plate enables the flexible extension and retraction of the limit post. Combined with the cooperation of the through rod and the support block, the connection wire harness is stably supported.

Benefits of technology

Significantly increases the ventilation area, reduces flow resistance, ensures stable power supply to the solenoid valve, avoids connection misalignment and wire harness tension, and guarantees efficient flow and stable operation of the FTIV valve.
