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.
