Description

 

What is the function of fuel injection pump?

 

Following are some of the major functions of the fuel injection pump:

 

1. Pumping fuel at high pressure: It is the main function of the fuel injection pump. The fuel injection pump draws fuel from a fuel tank and pumped it at high pressure to all injectors.


In an electronic fuel injection system, the fuel injection pump is used only for pressurizing the fuel line.

 

2. Metering of the fuel: The inline fuel injector pump helps to control the amount of fuel to be supplied to the injector.

 

3.Distribution of fuel: This is another important function of the fuel injection pump, to distribute the fuel to all the injectors at the exact time.

In inline fuel injection, the separate plunger and fuel barrel for each engine cylinder are used to supply fuel to all the injectors. In the distribution pump, the rotor helps to distribute fuel to all the cylinders.

 

4. Cooling of fuel injectors: The fuel injectors are directly subjected to the combustion process, thus the fuel injectors are subjected to a higher temperature. By pumping the low-temperature fuel into the injector, the fuel injection pump helps for the cooling of the fuel injectors.

 

Fuel injection pump types:
Following are the different types of fuel injection pumps used in diesel engines

 

  1. Inline fuel injection pump
  2. Distributor fuel injection pump
  3. 3.Continuous fuel injection pump

How does a Inline fuel injection pump work?

 

The inline fuel injection pump uses a plunger and fuel barrel to pump the fuel. The pump uses the number of plungers equal to the number of fuel injectors and all are arranged in the same line.

The schematic diagram for the inline fuel injection pump is shown below.

 

The fuel injection pump is ultimately controlled by a device known as a governor. The governor cuts the supply of fuel in event that the moving parts of the engine become too hot and endanger its life. This has the bonus of controlling the speeds a vehicle can reach in order to conform to local laws.
