Buyer’s Guide

How to choose the best injector cleaner

An injector cleaner is designed to remove carbon deposits from the inside of the engine cylinder head. Carbon buildup occurs naturally during combustion and causes problems such as poor performance and increased emissions. Regular maintenance using an injector cleaner will ensure optimum performance and reduce harmful exhaust gases.

In order to understand why an injector cleaner is needed it is important to understand how fuel injection works. During normal operation the air/fuel mixture enters the intake manifold where it is compressed and ignited. Once the spark plug fires the resulting explosion forces the piston downward into the cylinder. As the piston moves upward the valves open and allow the fuel-air mixture to enter the cylinders. At this point the valve closes again and the cycle repeats itself.

The Problem With Exhaust Gases

As mentioned earlier carbon builds up within the engine due to incomplete combustion. Over time this carbon build up reduces the efficiency of the engine and increases the amount of pollutants emitted. To combat these issues manufacturers have developed a number of different methods to improve engine performance. One method involves injecting additional amounts of fuel directly into each cylinder. This process is known as direct injection. However there are drawbacks associated with this type of technology. For example the high temperatures generated by the ignition source cause the injected fuel to vaporize prematurely. This results in incomplete combustion and higher levels of unburnt hydrocarbons (HC) and particulate matter (PM).

Benefits Of Using An Injector Cleaner

Using an injector cleaner will effectively eliminate carbon buildup and increase engine power output. Since the injectors are located near the top of the engine block they are exposed to heat and moisture which can lead to corrosion. Corrosion weakens the metal components of the injector and eventually leads to failure. Therefore regular maintenance using an injector cleaner will extend the lifespan of the injectors and maintain optimal performance.

Types Of Injector Cleaners Available

There are two types of injector cleaners available; manual and automatic.

The Importance of Purchasing a Quality Injector Cleaner

Injectors are responsible for delivering fuel into the combustion chamber of your engine. As the name suggests these devices act as a valve which opens and closes to allow air and fuel to enter the cylinder. Once inside the cylinder the mixture is ignited causing the piston to rise and power the vehicle forward. Without proper maintenance injectors can become clogged and cause problems with your car’s performance. To avoid costly repairs it is important to regularly check your injectors for signs of wear and tear.

There are several telltale signs that indicate your car needs an injector cleaner. First if your car has been running poorly there could be a problem with the injectors. Second if your car runs rough while driving especially when accelerating this could be caused by worn injectors. Third if your car seems sluggish when idling this could be due to poor injector function. Finally if your car starts making strange noises this could be a sign of injector issues.

    Start your car and let it idle for 5 minutes.

    Check the oil level in your car.

    Look at the dipstick.

    Pull the plug wire from the battery terminal.

    Turn the ignition key to the “on” position.

    Listen carefully for unusual sounds coming from your engine.

    Open the hood and listen closely for abnormal noise.

    Remove the spark plugs and inspect each one for cracks or chips.

    Examine the top of the head gasket for leaks.

    Use a flashlight to examine the underside of the engine block.

    Locate the distributor cap and remove it.

    Injectors are found in most internal combustion engines. The function of an injector is to spray fuel into the engine cylinder during the compression stroke. Fuel injection has become increasingly popular because it improves performance and reduces emissions. However there are many different types of injectors available today. Each type requires its own specific cleaning solution. Here are some features to look for when choosing an injector cleaner.


    The size of the injector determines the amount of fuel sprayed per cycle. Smaller injectors require smaller amounts of cleaner while larger ones require larger quantities. Most cleaners sold today are designed specifically for small-sized injectors. Larger injectors require a special cleaner which is formulated to remove carbon deposits and metal particles from the inside of the injector. Some injectors are very difficult to clean due to their design. Be careful when purchasing a product for these types of injectors.


    Most injectors are constructed using aluminum or steel. Aluminum is generally preferred because it is lighter weight and easier to machine. Steel is stronger and lasts longer. Both materials are susceptible to corrosion and rust. Corrosion occurs when water gets trapped between the injector body and the nozzle tip. Rust forms when iron combines with oxygen in the air. Many cleaners contain chemicals that attack both metals. Choose a cleaner that contains no harmful ingredients.

    Nozzle Tip Design

    Some injectors have a flat nozzle tip while others have a tapered shape. Flat tips allow for greater accuracy. Tapered tips provide a wider spray pattern. There are two main designs for tapered tips. One uses a straight taper while another uses a curved taper. Curved tips are more effective at spraying liquid fuel. Straight tips are best suited for gasoline applications where the mixture ratio is high. Always check the manufacturer’s recommendations regarding the proper cleaner for each type of injector.

    Different Types of Injector Cleaner

    Injectors are found in most internal combustion engines. The engine uses these devices to spray fuel into the cylinders where the mixture is ignited. There are two main types of injectors; mechanical and electronic. Mechanical injectors are still widely used today because they are cheap and easy to install. Electronic injectors are becoming increasingly popular due to their ability to precisely control the amount of fuel injected into each cylinder. However there are many different types of injector cleaners available. Some are designed specifically for certain vehicles while others are suitable for multiple makes and models. Here are some common types of injector cleaner.

    Mechanical Injector Cleaners

    These are the cheapest type of injector cleaner and are typically sold in aerosol cans. They contain detergents which dissolve carbon deposits and sludge build-up inside the injector. Most mechanics use these products to remove carbon deposits and sludge buildup from old injectors. Because they are inexpensive they are commonly used by hobbyists who wish to restore their cars. Although they are effective they cannot be used on newer electronic injectors. They must be replaced with a high quality product.

    Electronic Injector Cleaners

    The next step up from mechanical injector cleaners is electronic injector cleaner. These products are designed to clean both mechanical and electronic injectors. They contain special additives which break down carbon deposits and sludge buildup. Unlike mechanical injector cleaners they are safe to use on modern electronic injectors. They are also safer to use around children and pets since they are non-toxic and odor free.

    Fuel System Cleaners

    This type of injector cleaner contains chemicals which react with the fuel itself. As the fuel passes through the injector the chemical reacts with the fuel causing it to become acidic. Once the acidity reaches a critical level it causes the metal parts of the injector to corrode. This corrosion eventually leads to leaks and poor performance. Fuel system cleaners are only recommended for professional car repair shops and garages. They are very powerful and should only be handled by trained technicians.
