What is the purpose of baffle in fuel tank?
Baffles have been used for many years in fuel tanks to reduce the effect of the fuel sloshing when the vehicle is in motion. When a vehicle is moving, fuel can flow rapidly from one side of the tank to the other.
Does a fuel tank need a breather?
Your tank has to breathe. In order to breathe, your tank must have a vent somewhere that will relieve both vacuum and pressure. Gasoline expands in volume as it warms up and shrinks in volume as it cools down.
How does a baffle work?
Baffles work by disrupting the flow pattern and providing top to bottom flow. By ensuring that top to bottom flow is achieved in addition to swirling flow, baffles are able to prevent this from happening.
What is a baffled fuel tank?
Baffles inside the fuel tank help keep the pickup point for the fuel pump submerged in fuel so that the fuel pump is constantly pumping fuel to the engine. The rear baffle was too far back and that caused some issues with filling the tank, as well as allowing the fuel too much movement during hard acceleration.
How are the baffles on a fuel tank made?
The fuel tank is formed from blowing an extruded plastic tube (parison) outward to fill the mold cavity. Full height baffles are difficult to incorporate in the plastic tank design. Only partial height baffles can be integrated into the mold. See Figure 1 for typical manufacturing steps of a plastic fuel tank.
Do you need baffles on a rectangular tank?
In rectangular tanks the corners act to baffle the fluid and so baffles are not usually required unless vigorous agitation is needed, and so we will focus mainly on cylindrical tanks below. Standard baffle configuration utilises 3 or 4 equally spaced vertical baffles T/12 where T is the internal tank diameter.
Why are rear baffles important in drag cars?
Guerrero said, “If the rear baffle is not in the right place, it won’t control fuel slosh, there’s a balance to putting baffles in the tank. You can really bias a drag car tank. The first 60 feet needs help with fuel control.”
