Electronic fuel injectors began to appear in automobiles in larger numbers during the 1980s, slowly replacing
carburetors as the method to regulate fuel into the engine. Electronic fuel injectors use a series of components
which when connected together can provide better fuel efficiency, high performance and power as well as reduce
emissions. Over time buildup of residue and other particles can occur and a person will need to clean fuel
injectors to keep the engine running smoothly.
Very few carburetors are still in use today and the majority of vehicles on the market have some sort of
electronic fuel injection system. Fuel injection systems vary by make, model and manufacturer and can be direct
fuel injection, single point fuel injection, central port fuel injection, continuous fuel injection and multi point
fuel injection systems. All of these systems have similar parts and components with the difference being in how the
fuel is delivered into the engine and will require a person to clean the fuel injectors after extended use.
The common components found in an electronic fuel injection system include several sensors, fuel pump, wiring,
fuel injectors, engine control module and fuel pressure regulator. The engine control module is a mini-computer
which is connected to the other devices including the sensors. The sensors provide readings about oxygen levels and
other information into the computer, which then uses this information to control the amount of fuel being delivered
into the system. Keeping fuel injectors clean ensures the proper operation of this system.
When fuel injectors become clogged the engine control module will attempt to adjust fuel delivery into the
engine which can lead to excess fuel consumption. A person may notice a loss of power when accelerating, rough
idling engine and engine misfiring which creates a sputtering noise. When these problems occur it is important for
a person to clean the fuel injectors otherwise other problems with the system can develop which can lead to
complete engine failure.
There are different methods which a person can use to clean fuel injectors including gas additives and liquid
chemicals forced through the fuel rail by a mechanic or quick oil change shop. The problem with these methods is
the chemicals can damage other parts of the system, such as rubber O-rings and sensors. If there are problems with
cracks, leaks, loose springs and injectors stuck closed, there is no way to discover these problems without
removing the injectors from the vehicle.
When a person needs to clean fuel injectors the best method is to remove them from the engine and have a
professional fuel injector service company, like Injector RX, www.injectorrx.com, inspect, test and
clean the injectors. Injector RX will inspect the fuel injectors for cracks and leaks, replace any defective
parts, and perform tests which check spray patterns, fuel flow rate and coil resistance.
Injector RX will clean fuel injectors using an environmentally safe and biodegradable cleaner which offers the
most precise and safest way to clean fuel injectors. People have the option of mailing the injectors in for service
or dropping them off locally. To schedule cleaning of your injectors or for additional information visit the
