What is plunger injection pump?

The plunger unit of fuel injection pump (FIP) is an important mechanical parts of the Fuel injection pump. Which pump the incoming fuel with high pressure to the injectors through high pressure pipe line. Every fuel injection pump have plungers equal quantity of the engine cylinder.

What are the types of injection pump?

If you’re among this population of diesel-engine users, make sure that you know what type of diesel fuel pump you have.

  • Common rail fuel injection pump. …
  • Distributor (rotary) fuel injection pump. …
  • In-line fuel injection pump. …
  • Distributor injection pump.


How do I identify my Bosch injection pump?

The Bosch part number will be located on the component either on a parts ID tag riveted to the housing, on a parts sticker or printed onto the plastic moulding of the component.

How does a Bosch pump work?

The fuel gallery is charged with low-pressure fuel (15 to 75 psi). This permits fuel to flow into and through the barrel ports when the plunger does not obstruct them. The plunger reciprocates within the barrel; it is loaded by spring pressure to ride its actuating cam profile.

How does a plunger type fuel pump work?


So the flow is created over there and that goes and hit both the wells first it hits they let well you can see and it closes the inlet well very firmly and Inlet is firmly closed.

How does a diesel plunger pump work?

As the plunger moves back and forth, it leaves an opening for the fuel to go into the combustion chamber while moving backwards. While moving forwards, it creates enough force to compress the air in the chamber, which in turn creates enough heat to ignite the fuel and air mixture almost instantly.

What happens if you don’t code injectors?

Non start – In newer systems if you do not code in the injectors the vehicle will not start. Poor / lumpy running – as the injectors are not coded, the ECU will carry on fuelling as if the previous injector was still present, which can cause poor performance.

What do the numbers mean on fuel injectors?

Fuel Injectors are sized by their flow rate. Flow rate is a measurement of how much fuel can be delivered over time. It is listed in pounds per hour (lbs./hr.) or cubic centimeters per minute (cc/min.). The right size injector can supply enough fuel under full load conditions at an 80% duty cycle.

Do injectors have part numbers?

If your injectors have Data Match Technology matching they will have an alpha numeric serial number on them (AA00). On high impedance injectors i.e. 2150’s, 1100’s and 900’s you will find this code scribed into the lower stainless steel portion of the injector.

Which is better high or low impedance injectors?

That low-amp current keeps the injector temperature lower, which makes it more reliable; that’s why the high-impedance design is the most common injector style for OEM applications. Low-impedance injectors, also called peak-and-hold injectors, are sent a more powerful electrical signal, usually around 56 amps, to open.

What is Peak and hold injector?

Peak and Hold PRO Injector Driver is an advanced module designed to control low impedance injectors at a professional level, featuring 8 channels, 26-way automotive connector and several motor protections levels in case an injector or connection fails.
