Description
What is a Fuel Injection Pump?
Fuel injection pumps in diesel engines operate under high pressure.
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.
These devices are distinctly different from a fuel pump itself,
which is primarily responsible for the flow of the fuel from its
container or fuel tank. This is the part of the system in which
fuel is brought out of the tank and pumped along a system of tubes
to the engine block. The fuel injection pump then pushes the fuel
inside the cylinders.
Fuel injection pumps need to operate in high-pressure environments
in order to keep the system in full containment. In modern systems
this is at the level of 15,000 psi or higher. For this reason,
mechanics or engineers who work on these systems, especially
diesel, take great care for personal safety. The fuel injection
pump itself can possibly push fuel into the human body, causing
serious harm to an individual.
In larger models, a concept known as in-line injection is the
normal model. In this system, the pistons work with a throttle,
which can produce varying power levels in the engine. All of the
cylinders are rotated at once and the amount of fuel taken in is
adjusted by a volume control method.
The fuel injection pump is ultimately controlled by a device known
as a governor. The governor cuts the supply of fuel in event that
the moving parts of the engine become too hot and endanger its
life. This has the bonus of controlling the speeds a vehicle can
reach in order to conform to local laws.
