Description
What
are
Fuel
Injectors?
Fuel
injectors
are
parts
of
modern
car
engines
that
deliver
fuel
to
the
engine’s
combustion
chamber,
directly
or
indirectly.
These
small
electro-mechanical
devices
are
typically
positioned
at
a
certain
angle
to
make
sure
the
fuel
is
sprayed
towards
the
engine’s
inlet
valve
or
directly
into
the
cylinder.
How Does a Mechanical Fuel Injector Work?
A lot of folks confuse a mechanical fuel injection system with a carburetor. While the principle is fundamentally similar, there is a major difference in the type of fuel delivered to the engine. Whereas carburetor systems deliver low pressure fuel from the gas tank, a mechanical fuel injector delivers high pressure fuel to an accumulator. You can think of this as a temporary storage area for your fuel. The fuel then passes through a distributor which is typically considered as the metering control unit of the system. From here, the fuel is then ‘distributed’ into each cylinder in the correct amount and at the correct time.
fuel injectors
The flow of fuel that is injected into the inlet port is managed by the flap valve which is located in the air intake of the engine since air and fuel must be mixed first prior to entry into the cylinder. As you accelerate, the flap valve opens to increase the amount of air flowing through it. This also stimulates the fuel distributor to increase the amount of fuel pushed through the injector to maintain the right balance of air and fuel.
If fuel is not squirted into the inlet port, the valve inside the fuel injector remains closed by virtue of the tension on its spring mechanism. When fuel is sent to mix with air at the air inlet, the pressure of the fuel opens this valve to allow fuel to be squirted. This is the reason why they call mechanical fuel injectors to be spring-loaded injectors.
