What Is Fuel Pump?

A Fuel Pump Is a component in motor vehicles that transfers liquid from the fuel tank to the carburetor or fuel injector of the internal combustion engine.

What Is The Purpose Of Fuel Pump?

A fuel pump draws the fuel from the fuel tank through fuel lines and delivers it through a fuel filter to either a carburetor or fuel injector and finally to the cylinder chamber for combustion.

TYPES OF FUEL PUMP AND ITS WORKING PRINCIPLE:

The purpose of the fuel pump is to meter the correct quantity of fuel and deliver it at the correct time to the engine cylinder according to the varying load and speed requirements.

Types Of Fuel Pump:

The fuel pump is used in the fuel system to deliver fuel from the fuel tank to the carburetor. Many types of fuel pumps are used in modern automobile vehicles.

Two general types of fuel pump are as follows:

  • Mechanical Fuel Pump
  • Electrical Fuel Pump

How a Mechanical Pump Works

A mechanical fuel pump is driven by the camshaft , or by a special shaft driven by the crankshaft . As the shaft turns, a cam passes under a pivoted lever and forces it up at one end.

The other end of the lever, which is linked loosely to a rubber diaphragm forming the floor of a chamber in the pump, goes down and pulls the diaphragm with it.

When the lever pulls the diaphragm down, it creates suction that draws fuel along the fuel pipe into the pump through a one-way valve .

As the revolving cam turns further, so that it no longer presses on the lever, the lever is moved back by a return spring , relaxing its pull on the diaphragm.

The loosely linked lever does not push the diaphragm up, but there is a return spring that pushes against it.

The diaphragm can move up only by expelling petrol from the chamber. The petrol cannot go back through the first one-way valve, so it goes out through another one leading to the carburettor.

The carburettor admits petrol only as it needs it, through the needle valve in its float chamber (See How variable-jet carburettors work ).

How An Electric Pump Works

An electric pump has a similar diaphragm-and-valve arrangement, but instead of the camshaft, a solenoid (an electromagnetic switch ) provides the pull on the diaphragm.

The solenoid attracts an iron rod that pulls the diaphragm down, drawing petrol into the chamber.

At the end of its travel the iron rod forces apart a set of contacts, breaking the current to the electromagnet and relaxing the pull on the diaphragm.

When the diaphragm return spring raises the diaphragm, it also pulls the rod away from the contacts; they then close so that the solenoid pulls the rod and diaphragm down again.

Circulating Petrol Continuously

Most mechanical and electrical systems pump fuel only when the carburettor needs it. An alternative system has a complete circuit of pipes, from the tank to the carburettor and back again. The pump sends petrol continuously round this circuit, from which the carburettor draws petrol as it needs it.

Filtering Petrol and Air

Both petrol and air are filtered before passing into the carburettor.

The petrol filter be a replaceable paper one inside a plastic housing in the fuel line . A pump may include a wire or plastic gauze filter, and sometimes a bowl to catch sediment .

The air cleaner is a box fitted over the carburettor air intake, usually containing a replaceable paper-filter element .

The Fuel Pump Consists Mainly Of:

  • Pressure regulator.
  • Fuel level sender unit.
  • Impeller.
  • Armature.
  • Reservoir.
  • Strainers.

Does a Fuel Pump Run All The Time?

The fuel pump should only run continuously if the engine is running. The fuel pump will also run if the engine is off, but the ignition key is still in the on position.

What Controls a Fuel Pump?

The basic operating system for an electric fuel pump is relatively simple. When the key is turned on, the powertrain control module (PCM) closes the fuel pump relay, which activates the fuel pump for about three seconds to pressurize the fuel injectors.

How Do You Maintain a Fuel Pump?

Here are 4 good ways to ensure that your fuel pump lasts as long as possible:

  • Keep Your Fuel Tank Full As Much As Possible. The fuel pump is inside the tank.
  • Only Fill Up At Newer Gas Stations.
  • Don’t Fill Up When The Fuel Delivery Truck Is At The Gas Station.
  • Use A High Quality Replacement Fuel Pump.

Why Is a Fuel Pump Important?

The fuel pump generates a constant flow of fuel to the engine, and fuel not used is returned to the tank. This reduces the chance of fuel getting too hot since it is never kept close to the hot engine for very long. An in-tank fuel pump greatly reduces the risk of fire.
