ENGINES RUN ON AIR
(OXYGEN), FUEL, AND SPARK
The right
amount of fuel
needs to be
delivered at the
right time
More power, better
fuel economy,
fewer emissions!
Fuel injectors, both
mechanical and
electronic, have
been around for
over 100 years
A Fuel Pump
delivers fuel to
the Fuel Rail or
High-Pressure
Pump, both in
case of port and
direct injection
systems.
Gasoline Direct
Injection systems
route fuel through a
high-pressure pump
Fuel is constantly
supplied to the fuel
injectors under pressure.
Pressure is controlled
by a regulator, which
may be electronic,
vacuum, or mechanical
Fuel Injectors are
precisely machined so
they can deliver a
consistent fuel charge
Can interrupt
the fuel spray
Cylinder
Misfire
Hard

Incorrect
Fuel Trim
Poor fuel
economy
Poor

Can stop up
the fuel injector
completely
Might even
hold an injector
open
Blockage
by carbon
deposits or
dirty or
aged fuel
Until the 1980s, carburetors
were used to deliver fuel
with the air, but this wasn’t
efficient enough.
Electronic fuel injection can be
more precisely controlled

DON’T WORK
ENGINE PROBLEMS MAY STEM FROM
DIRTY OR BLOCKED FUEL INJECTORS

The Engine Control
Module delivers one or
more electrical pulses to
open the fuel injectors
and deliver fuel

Injector Cleaner can
be added as often
as every fill-up, a
great way to
maintain a clean

REGULAR
STRENGTH
Regular-Strength Fuel
Injector Cleaner can
be used every three to
five fill-ups. Stronger
cleaning agents help
to rid your fuel system
of deposits and
protect it from
corrosion.

PREMIUM
STRENGTH
Premium-Strength Fuel
Injector can be poured
into the tank every
7,500 km or 10,000
km, at the oil change
interval. Stronger
additives offer deeper
cleaning for built-up or
stubborn fuel system
deposits.
