Air intake apparatus for vehicle fuel system, has fuel inlet space partially isolated from outside of vehicle body, such that air which is more pure than air outside of body flows into air intake space and then to air filter

摘要

The apparatus has an inner pipe and an outer pipe formed such that a fuel inlet space (17) and an air intake space (35) are in communication with each other. The fuel inlet space is partially isolated from an outside of a vehicle body by the body and a fuel cap door, such that air which is more pure than air outside of the vehicle body flows into the air intake space and then to an air filter through an air supply pipe.
