What is plunger injection pump?

Fuel Injection Pump is another important part of fuel injection system in automobile engineering. The Fuel Injection Pump is used in the individual pump system of a solid injection. It consists of a plunger driven by a cam and tappet mechanism at the bottom.

What is the function of a plunger in an injection pump?

The plunger displaces the available volume through its own volume and increases the pressure of the fluid to be pumped. The suction valve closes and the pressure valve opens the way into the process area for the pressurized fluid.

What is fuel plunger?

The plunger and barrel are important parts of your engine’s fuel injection pump, feeding fuel into the cylinders through the fuel injector valve. Any wear or defect to the plunger and barrel can lead to wrong injection timing and consequently poor combustion and subsequent damages.

How does a plunger type fuel pump work?

Plunger-type fuel pump It is similar to that of a piston pump, but the high-pressure seal is stationary while the smooth cylindrical plunger slides through the seal. A spring is used to pull the plunger outward creating a lower pressure pulling fuel into the chamber from the inlet valve.

How does a plunger pump work?

Rotary piston and plunger pumps use a crank mechanism to create a reciprocating motion along an axis, which then builds pressure in a cylinder or working barrel to force gas or fluid through the pump. The volume of the fluid discharged is equal to the area of the plunger or piston, multiplied by its stroke length.

Is a plunger pump a positive displacement pump?

A plunger pump is a type of positive displacement pump where the high-pressure seal is stationary and a smooth cylindrical plunger slides through the seal. This makes them different from piston pumps and allows them to be used at higher pressures.

How does increasing or decreasing effect the fuel injector delivery of fuel?

The fuel injector meters the fuel more precisely than a carburetor. Therefore, no fuel is wasted. The result of such precise metering is increased power, lower emissions and lower fuel consumption.

How do I bleed injector pump?

How to Bleed an Injector Pump

  1. Step 1 – Check Fuel Lines.
  2. Step 2 – Remove Valve Cover.
  3. Step 3 – Open Fuel Cut-off Valve.
  4. Step 4 – Bleed the Injector Pump.
  5. Step 5 – Finish the Job.

What are signs that your fuel pump is going out?

Seven Signs Your Fuel Pump Is Going Out

  • Sputtering Engine. Your fuel pump is telling you something if your engine starts to sputter once you’ve hit the top speed on the highway.
  • Overheating Engine.
  • Low Fuel Pressure.
  • Power Loss.
  • Surging Engine.
  • Gas Mileage Decrease.
  • Dead Engine.
