How does the gas pump automatically shut off when the tank is full?
Automatically shutting off of the pump may seem like an “out-of-your-league” electric process, but actually, it’s not an electric process at all. In fact, it is a mechanical process – and a rather innovative one at that! It involves a very interesting physical phenomenon, known as the Venturi effect.
What happens when there is no gasoline in the tank?
It also contains air; as your vehicle runs and gasoline is used, the space that it vacates is instantly occupied by air. This means that when there is no gasoline left in the tank, it’s still filled, but only with air. What’s Inside the Pump Nozzle?
What should you do if you get gasoline in your car?
Find out what type of gas cap your vehicle’s tank has and always use caution when opening. If your vehicle has a vented gas cap there is minimum risk of being sprayed with gasoline. If you drive an older vehicle, ensure that you slowly open the gas cap to release any pressure that has built within the tank.
Why does the gas nozzle shut off when the gas tank is full?
This causes the spray from the nozzle to no longer be uniform (which is how we design our fuel fillers), causing turbulence in the fuel filler pipe, bouncing back, and momentarily blocking the venturi on the fuel nozzle. Also, one correction to Torch’s article is how a gas nozzle actually shuts off when the fuel tank is full.
Where does the gas pump go to fill the tank?
Next time you go to a gas pump, take a closer look at the pump nozzle (i.e., the thing that goes inside the tank of the vehicle to fill it). Upon inspection, you will find a small, half-inch hole at the end of it.
Why does the gas pump keep shutting off?
A majority of fuel systems have two primary fuel tank vents, one going to the evap canister (which is how the system displaces the air in the tank per the article you are referencing) and another going to the fuel filler pipe. The line going to the filler pipe is actually used to reduce the amount of vapor generated during refueling.
It also contains air; as your vehicle runs and gasoline is used, the space that it vacates is instantly occupied by air. This means that when there is no gasoline left in the tank, it’s still filled, but only with air. What’s Inside the Pump Nozzle?
