Fuel Injector Cleaner Buying Guide

The fuel injection system is a system used in the admission of fuel into the combustion chamber. This has become the basic fuel injection system replacing the carburetors. Carburetor engines were discontinued in the 1990 and now most vehicles on the road use fuel injectors. The difference between the two is that while carburetors use suction in the intake air to draw a fuel stream in the chamber, fuel injectors atomize fuel through small nozzles under high pressure.

Modern fuel injectors are designed for specific fuel types and while some fuel injection systems can adapt to different fuels using sensors, most injector systems are for gasoline and diesel.

There are different functional objectives for fuel injectors. All of the systems will share one task of supplying the fuel to the combustion chamber but the optimization of a system depends on the design. Some of the competing objectives include the power output, fuel efficiency, reliability, driveability, ability to adapt to alternative fuels, emission performance, initial cost, maintenance cost, engine tuning, range of environmental operations, and diagnostic capability.

Modern fuel injectors are in a better position to optimize these objectives than earlier fuel delivery systems such as the carburetor and older versions of the fuel injector systems.

Understanding The Fuel Injector

Prior to looking at why you need to clean your fuel injector and the benefits of having a clean injector, it is important that we understated how the fuel injector works. As mentioned above the fuel injector used in most vehicles today replaced the carburetor to improve on efficiency and fuel consumption. Fuel injectors in modern vehicles are part of a computerized system which enables them to spray fuel efficiently at calculated intervals.

There are number of different fuel injectors and the basic type is referred to as a throttle body injector. This system works just like a carburetor only that it is computerized. It uses one injector that delivers fuel across the combustion chambers of the engine. This injection system resembles a carburetor as it is located on top of the engine and is designed in such a way that it delivers fuel to all cylinders of the engine.

Electronic Fuel Injection

The electronic fuel injection system better known as EFI is a more advanced fuel injection type. In this system, each cylinder has its own fuel injector and the system uses a multi-port fuel injection method to deliver the fuel. Basic multi-port setups will spray fuel into the cylinder regardless of whether the cylinder is firing or not. For this reason, there is an advanced electronic fuel injection system using sequential multi-port system which ensures that the fuel is only sprayed before the cylinder fires. This results in better performance and when the driver accelerates the system immediately increases fuel delivery without waiting for a full revolution.

The electronic fuel injection systems are complicated systems that include more than just the injectors. The system is controlled by a central computer which is responsible for determining when the injectors need to spray and the amount of fuel to be sprayed. To be effective and efficient, there are sensors which send information to the computer for adjustments. For instance, there is a throttle position sensor which notes the position of the gas pedal and sends the information to the computer for a change in fuel amount delivery.

The oxygen sensor is another sensor that monitors the levels of unburnt fuel in the exhaust system. When the sensor notes that there is too much unburned fuel in the exhaust gases as a result of rich fuel in the engine, its sends this information to the computer which in turn prompts the injectors to deliver less fuel to the combustion chambers.

Though electronic fuel injectors are complex in their setup and operation, and need computerization, the delivery of fuel by these systems is more precise and well controlled. These injectors make it possible to protect the environment by avoiding unnecessary fuel combustion and reduce the level of poisonous emissions. Your car will get better acceleration and power controlled by the computerized system.

Benefits Of Fuel Injectors

Fuel injectors have quite a number of benefits over the earlier fuel delivery methods such as carburetors. Some of the benefits include a more consistent throttle response which is experienced during fast throttle transitions. With a fuel injection system, you will experience easy cold starting, precise adjustments that handle the changes in air pressure and temperature and a more stable idling. With a fuel injector, the maintenance needs will decrease and your engine will have better fuel consumption and efficiency.

A fuel injection system will dispense with need for separate mechanical chokes, which must be adjusted as the engine warms up in carbureted vehicles.

Fuel injectors also have the benefit of having the ability to provide the stratified combustion which was not achieved in carbureted engines.

Fuel injector systems have brought about the possibility of changes in the cylinder settings because the electronic gadgets inject fuel into the cylinders individually. This is something that was not possible with carbureted engines since the carburetors could not deliver fuel between cylinders unless there was a complex individual carburetor for each cylinder. Fuel injectors can operate normally regardless of the orientation and this means that the engine will work upside down or in zero gravity such as the case with airplanes. This provides a wide play for engine applications unlike the limitations by carburetors.

Environmental Benefits

Fuel injectors have been found to greatly improve the efficiency of the engine. Multi-point fuel injection systems provide an improved cylinder-to-cylinder distribution and this leads to less fuel consumption but with the same power output. Variations in cylinder-to-cylinder distribution can lead to excess fuel in some cylinders resulting from the need to ensure that all cylinders receive sufficient fuel. The fuel injection system balances this distribution and ensures that each cylinder receives the needed amount of fuel.

Fuel injection systems have contributed a great deal in reducing the exhaust emissions from engines. When the combustion process is receiving the fuel amounts it needs, there will be no unburnt fuels and the emission will be cleaner. The controlled fuel delivery handled by the computerized fuel injection ensures that the precise amount of fuel is delivered into the combustion chambers. With an addition of catalytic converters, the exhaust fumes will be cleaners and this will help a great deal in protecting the environment.

Dirty Or Clogged Fuel Injectors

Due to their extended use, quality of fuel and other elements such as temperature, fuel injectors are bound to get dirty and the substances making them dirty might clog the passages and compromise their performance. Some of the substances that might clog the fuel injection system include carbon deposits and substances resulting from stale fuel. For this reason, it is important that you understand the signs of clogged fuel injectors so as to clean them to restore your engine’s performance.

Some of the symptoms of a blocked or clogged fuel injection system include a hard start, hesitation of the throttle tip, pre-ignition which is heard as a ping sound decreased fuel efficiency and gas mileage, rough idle and poor overall performance of the engine. Knowing these symptoms will give you a clue when you need to use the best fuel injector cleaners to unclog the system and give your engine its performance and efficiency back.

When To Use Fuel Injector Cleaners

When the engine is running, you cannot see the business end of the injectors. It can take quite some time to access the fuel injectors; you can follow a practice of cleaning the injection system based on time or mileage. It is recommended that you clean your fuel injectors 1-3 times every 36 months. If you are using mileage, then you can clean the injectors once or twice after 45,000 miles.

The difference vehicle owners experience after using fuel injector cleaners is amazing and this should be considered a regular tune up for the fuel injection system. While most engine parts can be replaced without any notable changes, you will feel when a clogged fuel injector as been cleaned because your vehicle will perform better and have more power.

Keeping Your Fuel Injector Clean

While vehicles manufactured from 2004 will need less cleaning, because they use newer designs that also accommodate fuel additives which help in keeping the injection system clean, they will still need some cleaning because of low quality fuel and extended use. It is however important that you insist on high quality fuel that will not compromise the operation of the fuel injection system and other involved parts because they will generally affect the performance of the engine.

Benefits of a Clean Fuel Injection System

The benefits of a clean fuel injection system are simple and straight forward. When you use the best fuel injector cleaners, your vehicle will perform better, have more power and improved fuel efficiency. Most people who have used fuel injector cleaning kits and fuel injector cleaning solutions have reported a great improvement in gas mileage and reduction in emissions. A clean fuel injector pump results in an optimally operating engine and reduced maintenance cost.

Efficient Combustion – When the correct amount of fuel is injected into the cylinder, the combustion will be highly efficient. This will only happen if the spray is correct. Dirty fuel injectors will result in compromised fuel flow and disrupted fuel sprays. Since the opening of the fuel injector is tiny, the smallest particle or deposit can greatly affect the spray pattern and fuel delivery. The result of an affected spray is lean misfire, loss of power and troubled starts. To ensure that the combustion process is efficient, the fuel injectors need to be cleaned using the most effective fuel injector cleaners.

Engine Performance – An improperly functioning fuel injector will lead to a number of issues that will generally affect the performance of the engine. Because of the associated irregular supply of fuel the engine will fluctuate between high and low rpms and this will compromise the power delivery. When the fuel injectors are properly cleaned and maintained, the engine will be reliable and smooth.

Improved Mileage – If the fuel injectors get clogged, the computerized fuel system will try to compensate the low fuel supply and this might lead to excess injection of fuel. This is what causes high fuel consumption but the engine power will still be low. For better mileage clean your fuel injectors regularly.

Emissions – The cone mist produced by a perfectly working fuel injector ensures that the fuel vapor is combusted properly. Clogged fuel injectors will deliver the fuel in streams that might result in poor combustion and this will increase the poisonous emissions. Clean your fuel injectors to ensure that the delivery is in vapor mists that will be combusted efficiently.
