Fuel injectors are the parts in your engine that take gasoline
from your vehicle's fuel system and transfer it in precise amounts
to the cylinders where the gas is burned.
Like miniature garden hose nozzles, which can be set to spray
a specific pattern and amount of water. injectors spray fuel into
the cylinders in an exactly shaped pattern and in an exact amount
that gives your vehicle proper ignition and maximum power. The
shape of the injector's spray pattern and its volume - the amount
of fuel being sprayed at any given time - are absolutely
critical to your engine's performance. Contamination can cause
a slight change in the spray pattern or volume and that results
in your engine losing power.
So, what causes ditty injectors? Well, in most cases deposits
form over time in the chamber of the injector and on its tip.
The additives in the gasoline you burn usually cause these deposits.
Switching brands or to a higher octane rating won't help, all
gasoline sold in this country have these additives.
What happens is the contaminants aren't burned up inside the
cylinders? Instead, they begin to bake onto the first hot surface
they encounter - your fuel injectors. As these deposits build
up, they change the shape and volume of the injector's spray pattern.
Fuel injector deposits are a natural side effect of the combustion
process and there's nothing you can do to avoid them.
Gasoline additives, although marketed as a means to clean your
injectors actually are not terribly effective.
The ability of the solvents they contain to clean your injectors
are greatly reduced when mixed with gasoline. Even
detergent-grade gasolines are no, Suspected by some
oil companies of actually contributing to fuel injector contamination.
Often it's hard to tell when dirty injectors are robbing your
engine of power, because just as the deposits build up gradually,
the vehicle's power and performance decreases gradually.
Occasionally an injector can become seriously clogged or plugged.
This can cause hesitation, stumble and a sudden and noticeable
loss of power. These symptoms are most noticeable when your injectors
have to work the hardest - during warm-up or when you accelerate.
Hard starting and rough idling can also be indications that your
injectors need cleaning, or in extreme contamination, replacement
of one or two of the injectors.
To prevent major fuel injector problems, regular professional
cleaning is recommended. A good rule of thumb is every 1,500 -
2,000 gallons of gas burned - every 50,000 kilometres or so. Cleaned
regularly, fuel injectors should last for tens of thousands of
Kilometres of driving.
