Description
What is the Fuel injection Pump?
The fuel injection pump is the heart of the fuel injection system
in the diesel engine. For the proper combustion in the diesel
engine, the fuel injection pump performs a vital role. Thus in this
article, we will be discussing about the fuel injection pump.
Fuel injection pump (FIP) is the device used in the diesel engine
for pumping the fuel to the injectors and it also helps to
distribute and meter the supply of fuel to all injectors. The other
function of the FIP is to pump the correct quantity of fuel at the
right time (Just before the piston reaches TDC during compression
stroke) and within a specified duration.
Along with this some fuel injection pump also helps to distribute
the fuel to all the cylinders of the multicylinder engine as per
their firing sequence.
A device that pumps fuel into gasoline or diesel engine cylinders
is known as a fuel injection pump. The pump is usually driven by a
chain or toothed timing belt that is motivated by the gears in a
crankshaft. This system is also linked to the camshaft, causing
them to be intertwined. In traditional four-stroke engines, it
rotates at half the speed of the crankshaft in order to enable the
correct timing of the injection process. This occurs as the
cylinder's compression stroke is about to begin.
Smaller engines, such as those in cars and light trucks, use a
distributor pump to control the fuel injection process. The
injector pumps gas or diesel into fuel lines, which is how the
volume of fuel is controlled. The timing of the injection process
is controlled by the crankshaft. Essentially, the faster a vehicle
moves, the more fuel is injected into the internal combustion
engine. This can be accented with the addition of a turbocharger or
supercharger, which gives the engine more power.
