The changes of the times have caused more and more manufacturers to pay more attention to the user experience, especially the problem of vehicle noise, which has attracted more and more consumers and car owners.


In order to provide customers with a better experience, many OEMs use a lot of technology between the fuel pipe and the engine to reduce engine idle noise, including changing fuel pipe materials, adding silencers, etc., which leads to increased costs. Fuel leakage may occur due to different materials.


In the prior art, the fuel line is directly connected between the engine and the fuel tank, the fuel line is not fixed, and the fuel line is suspended in the vehicle body, thereby the pressure of the fuel tank and the vibration of the engine during the operation of the engine. This causes the fuel line to vibrate to generate noise, and can cause the fuel line to move, affecting the performance and experience of the entire vehicle.

A novel technical solution provides a fuel line system for use in a vehicle, including an engine, a fuel tank, and a canister for absorbing oil vapor; wherein the engine is fixedly mounted on an engine mount bracket; the fuel tank and the carbon The canister is connected by a first fuel line; the canister is connected to the engine through a second fuel line; at least one fixing clip is further disposed on the engine suspension bracket; the first fuel pipe The road is fixed to the engine mount bracket by the fixing clip.


Further, the carbon can is filled with activated carbon.


Further, the fixing clip includes at least one through hole, and at least three top protruding protrusions are evenly distributed on an inner surface of the through hole; the first fuel line passes through the through hole, The top tight projection is urged against the outer surface of the first fuel line.

Further, the top protruding protrusion is an elastic protrusion.


Further, the inside of the hole wall of the through hole has a mounting cavity, and an expansion spring is disposed in the mounting cavity; the top fastening protrusion portion includes a main body portion and a hemispherical head integrally formed with the main body portion. The body portion is slidably coupled to the cavity wall of the mounting cavity, the body portion is coupled to the expansion spring, and the hemispherical head protrudes from an outer side of the mounting cavity and faces the The center line of the through hole extends.


Further, a guiding groove is disposed on the cavity wall, and a protruding rail is disposed on the main body portion, and the protruding rail is slidably connected to the guiding groove.


Further, a protruding rail is disposed on the cavity wall, and a guiding groove is disposed on the main body portion, and the protruding rail is slidably connected to the guiding groove.


Further, the fixing clip includes a fixing clip fixedly disposed on the engine suspension bracket and a movable clamp member for cooperating with the fixing clip; the fixing clip and the movable clamp member are both An arcuate groove is provided; two correspondingly disposed arcuate grooves abut to form the through hole; the fixing clip and the movable clip are connected by a fastening bolt.


Further, the second fuel line is also fixed to the engine suspension bracket by the fixing clamp; the second fuel pipe passes through the through hole, and the top tight convex portion is topped Immediately on the outer surface of the second fuel line.


Further, the first fuel line and the second fuel line are respectively fixed to the engine suspension bracket by a plurality of the fixing clips.


Since the first fuel line is fixed to the engine suspension bracket by the fixing clip, the degree of freedom of the first fuel line is limited, the vibration of the first fuel line is reduced, and the first fuel line is lowered. The noise generated by the vibration improves the performance of the vehicle.
