A method can be used to form a plastic filler neck for a vehicle. The method includes providing a fuel injection pipe comprising a polyamide material containing nanoclay and having a single layer structure in cross-section, inserting and fastening a retainer into an internal space of a tip of the fuel injection pipe to support a refueling gun, directly fastening a cap holder to the tip of the fuel injection pipe, and mounting an air drain casing to an outer diameter portion of the cap holder fastened to the fuel injection pipe using a mounting bracket.

Plastic filler neck for vehicles

A plastic filler neck for vehicles includes a fuel injection pipe, a retainer inserted and fastened into an internal space of a tip of the fuel injection pipe to support a refueling gun, a cap holder directly fastened to the tip of the fuel injection pipe by fusion, and an air drain casing mounted, by a mounting bracket, to an outer diameter portion of the cap holder fastened to the fuel injection pipe.

A canister close valve device for opening or closing a passage provided between a canister, which collects evaporation gas evaporated from a fuel tank and the atmosphere may include a plunger configured to selectively move up or down through magnetization with a core inside a valve housing when a solenoid is activated, a rod configured to perform a rectilinear reciprocating movement toward or away from the passage due to the upward/downward movement of the plunger, and a diaphragm valve body, which is inserted into the plunger, is connected to the valve housing, and is configured to be deformed by the upward/downward movement of the plunger and to generate force for impeding the upward/downward movement of the plunger using a pressure difference generated between the plunger and the valve housing.
