What is plunger and barrel in fuel injection pump?
In a conventional fuel injection pump of a diesel engine, fuel is sucked in and expelled under pressure by the reciprocating action of a plunger in a fuel chamber formed in the plunger barrel.
What is plunger in fuel 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 two types of fuel pumps?
Two general types of fuel pump are as follows:
- Mechanical Fuel Pump.
- Electrical Fuel Pump.
What are the 2 types of injection pump?
The main types of injection systems include pump-line-nozzle, unit injector, and common rail. Modern injection systems reach very high injection pressures, and utilize sophisticated electronic control methods.
What is the function of plunger?
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.
How does a plunger pump work?
The plunger or piston is actuated by a steam powered, pneumatic, hydraulic, or electric drive. 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.
What are the 4 common types of fuel 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 difference between distributor type injection pump and inline plunger injection pump?
The inline type uses one plunger for one injector, but the distributor type uses a single plunger for all injectors. The way it works, this plunger will press all the fuel in each fuel barrel alternately. The fuel barrel is placed around the pump shaft.
What is the difference between fuel pump and fuel injector?
A fuel injector atomizes the pressurized fuel. It also injects it into the combustion chamber. In comparison, fuel pumps pressurize fuel and send it through the fuel line and fuel injectors. Fuel injectors decrease the pressure within fuel systems, and fuel pumps increase the pressure within the fuel system.
Where is plunger pump used?
This type of pump is often used to pump municipal and industrial wastewater. Piston pumps, sometimes referred to as piston pumps, have a reciprocating plunger that moves back and forth, forcing fluid through a series of valves.
How does a plunger pump works?
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 pressure in the chamber actuates the valves at both the suction and discharge points.
What is the difference between plunger and piston pump?
The difference between a piston and plunger pumps is the high-pressure seal. In a piston pump, the seal is attached to and reciprocates along with the piston. Because of this, piston pump seals wear out faster and cannot handle as much pressure compared to plunger pumps.
What is plunger stroke?
Answer.An effective plunger stroke is stroke from the time of the top of the plunger covers the inlet port untilthe helix uncovers the spill port. The grater the effective stroke, the grater the injected fuel quantity.
What are the 2 types of fuel pump?
The two most widely used fuel feed pumps are diaphragm and plunger-type mechanical pumps. Diaphragm pumps are a type of positive displacement pump. Diaphragm pumps contain a pump chamber whose volume is increased or decreased by the flexing of a flexible diaphragm, similar to the action of a piston pump.
What are the 3 types of fuel pumps?
Types of Fuel Pumps: Mechanical, Electric & High Pressure Fuel Pump.
Why is petrol called gasoline?
Petrol’ is a shortened term for ‘Petroleum Distillate’ which is what it is. Gas is a shortened version of ‘Gasoline’ was a trade name for Petroleum Distillate used in the US. Diesel is the fuel used in Diesel engines which were invented by Rudolf Diesel so unsurprisingly it is called diesel in germany!
What is called the best fuel?
Natural hydrogen is always associated with other elements in compound form such as water, coal and petroleum. Hydrogen has the highest energy content of any common fuel by weight. On the other hand, hydrogen has the lowest energy content by volume.
What are the two types of fuel injection pump?
The distributor pump’s main feature is the injection system. The distributor type uses a single plunger for all injectors, while the inline type uses one plunger for one injector.
