Description

 

What is the fuel pump and What role does it play in engine?

 A fuel pump is a very important gadget on a car or the other internal combustion engine device. It's mainly function to supply fuel away from the engine to the other parts through a pressure. There are two types of fuel pumps. One is mechanical fuel pump and the other is electric fuel pump. Mechanical fuel pumps have regularly fixed outside the fuel tan.

 

How does the fuel pump work?

 

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.

 

Precautions for using oil pump

 

A high quality, OEM fuel pump can last indefinitely. However, as with any electro-mechanical component, a fuel pump will eventually degrade and fail. When the fuel pump used last a long time,and the engine begin to appear black smoke  one after another so that the engnine can not went down. If it fails to produce adequate pressure or completely quits operating, and  it will need to be replaced.
