Best Fuel Injector Cleaners and System Additives in 2017 – Buyer’s Guide and Reviews

fuel-injector-2

Fuel injection was one of the most important automotive advances of the 20th century. Fuel injection is aptly named because it is a method of introducing fuel in an internal combustion engine via an injector. Up until the 1980’s, most cars used carburetors. However, since the 1980’s, most cars have switched to fuel injection because of the many advantages fuel injection has compared to carburetors.

In order to inject fuel into a car’s engine, your gas pump delivers gasoline to a small nozzle inside the fuel injector. The gas is then converted into a mist under high pressure and sprayed into the engine. This mist is able to deliver the proper amount of fuel to a car’s engine, thereby increasing efficiency. Carburetors, on the other hand, rely on suction created by intake air to draw fuel into the engine.

Fuel injection offers many advantages. Not only do fuel injected engines have smoother and more consistent throttle response, but they also easier cold starting, more stable idling, better fuel efficiency, and decreased maintenance needs. Even though fuel injectors offer all of these benefits, it was their environmental friendliness that eventually caused their widespread adoption in automobile manufacturing. In the 1970’s and 1980’s, the U.S. and Japanese governments imposed increasingly strict exhaust emissions regulations. In order to comply with these strict regulations, manufacturers initially started developing more and more complicated carburetors. Even though basic carburetors are cheaper to manufacture than fuel injectors, these more complicated carburetors proved to be more expensive than fuel injection. Thus, most automobile manufacturers started switching to fuel injected engines.

Because fuel injectors are an integral part of a car’s engine, it is very important to clean them on a regular basis and make sure they are operating properly. If you don’t clean your fuel injector you are likely to encounter a variety of problems such as:
• Fuel injector may become blocked or dirty due to carbon, gum or varnish deposits
• The fuel injector nozzle may develop leaks
• Fuel injectors may not open or close properly
