A gasoline pump or fuel dispenser is a machine at a filling station that is used to pump gasoline (petrol), diesel, or other types of liquid fuel into vehicles. Gasoline pumps are also known as bowsers or petrol bowsers (in Australia and South Africa), [2] [3] petrol pumps (in Commonwealth countries), or gas pumps (in North America).
Fuel injected engines use either electric fuel pumps mounted inside the fuel tank (for lower pressure manifold injection systems) [1] or high-pressure mechanical pumps mounted on the engine (for high-pressure direct injection systems). Some engines do not use any fuel pump at all. A low-pressure fuel supply used by a carbureted engine can be ...
Pay at the pump is a system used at many filling stations, where customers can pay for their fuel by inserting a credit card, debit card, or fuel card into a slot on the pump, bypassing the requirement to make the transaction with the station attendant or to walk away from one's vehicle.
In some regions of Canada, the term "gas bar" (or "gasbar") is used. In the rest of the English-speaking world the fuel is known as "petrol". As a result, the term "petrol station" or "petrol pump" is used in the United Kingdom. In Ireland, New Zealand and South Africa "garage" and "forecourt" are still commonly used.
The negative pressure created by a vacuum pump typically located in the fuel dispenser, combined with the pressure in the car's fuel tank caused by the inflow, is usually used to pull in the vapors. They are drawn in through holes in the side of the nozzle and travel along a return path through another hose.
Although gas prices have dropped from their all-time highs, the current national average of well over $3.00 per gallon still has consumers feeling the pinch at the pump.
Petrol pump may refer to: fuel dispenser, a device at a filling station that dispenses fuel; filling station, a facility that sells fuel and lubricants for motor vehicles
In 1891, the British Herbert-Akroyd oil engine became the first engine to use a pressurised fuel injection system. [28] [29] This design, called a hot-bulb engine used a 'jerk pump' to dispense fuel oil at high pressure to an injector.
