What are the types of injection pump?

Know Your Vehicle: The 4 Types Of Diesel Fuel Pumps

  • Common rail fuel injection pump. An electronically controlled diesel fuel supply system, this pump was developed to meet the strict 21st century exhaust gas regulations.
  • Distributor (rotary) fuel injection pump.
  • In-line fuel injection pump.
  • Distributor injection pump.

What is the function of injection pump?

An Injection Pump is the device that pumps fuel into the cylinders of a diesel engine. Traditionally, the injection pump was driven indirectly from the crankshaft by gears, chains or a toothed belt (often the timing belt) that also drives the camshaft.

How much does it cost to replace an injection pump?

To get your injector pump replaced, you are looking at anywhere from $1,400 to $1,875. For labor, you should pay between $770 and $1,000, while parts will run between $685 and $900.

What is the working principle of a fuel injector pump?

Working principle a Petrol Injector: While high pressure-injectors inject the petrol into the combustion chamber, it improves combustion chamber cooling. This enables higher engine efficiency due to higher compression, which, in turn, increases fuel efficiency and torque.

Who uses injection pump?

Injection pumps are designed to inject measured amounts of fluid into a reservoir or production system. They are often used in vehicles for pumping fuel into the cylinders of the engine. Injection pumps are positive displacement pumps that use expanding and contracting cavities to move fluids.

How long does it take to change a fuel injection pump?

The labor to replace the in tank fuel pump and the inline fuel filter that should be replaced with the fuel pump will take 4 to 5 hours labor.

What is injection Control in CI engines?

The injection pump sends fuel under pressure to the nozzle pipes which carry fuel to the injector nozzles located in each cylinder head. CI engines are operated unthrottled, with engine speed and power controlled by the amount of fuel injected during each cycle.

How does a distributor fuel injection pump work?

The fuel barrel is placed around the pump shaft. When the pump shaft rotates, the plunger will press the fuel in the fuel barrel alternately according to the ignition timing. Even though it has a smaller design, the distributor pump does not have high fuel pressure. Therefore, this type is rarely used for high capacity diesel engines. 3.

Which is the latest type of diesel injection pump?

Continuous pump is the latest type of diesel injection pump. As I said earlier, this type is actually the most widely applied today. Continuous pump is an injection pump that is applied to the common direct injection system. Judging from the physical, this pump has the smallest form of all types that we discuss.

Which is the smallest type of fuel injection pump?

Continuous pump is an injection pump that is applied to the common direct injection system. Judging from the physical, this pump has the smallest form of all types that we discuss. The reason is this pump only has a single function. Its function is only to increase fuel pressure stably at high pressure.

What makes an inline injection pump an inline pump?

It can be say, the number of plungers is the same as the number of injectors. However, all the plungers are placed together in one pump unit in a line position. That is what causes this pump also called the inline injection pump.
