![]() Since carburetors were phased our around 1980, every new internal combustion engine gets the fuel into the chamber with injectors, including diesel engines (don’t use a gas engine-only injector cleaner in a diesel, though). Newer injectors for direct injection engines even have several nozzles on the tip to help for a better air-fuel mixture. The fuel injector works similarly, with higher much pressures, smaller nozzles, and precise metering to create a fuel vapor that combusts predicably, efficiently, and cleanly. It’s a little like an aerosol spray can: A bottle already pressure with a small nozzle that atomizes the liquid into very small particles. The injector receives the fuel from a high-pressure fuel pump and thanks to a very small nozzle, atomizes the fuel so it can mix with air quickly. Here, we’ll talk about everything you need to know about fuel injector cleaners and we try to answer every question you have, like why they are needed in the first place, how to use them, should you use them yourself, or go to a mechanic, and so on.įuel injectors are used to introduce fuel to the combustion chamber, where it is mixed with air and then combusts to create power. That is, if it doesn’t have other problems already. Clogged up fuel injectors are so common that every auto parts shop has dozens of different fuel injector cleaners that purportedly can clean your entire fuel system and make your engine work like new again. If you’ve never experienced your engine losing power even if it was regularly maintained, you are one of the lucky few. ![]() If you think about it, these are one of the vital parts of the engine-no fuel in the chamber means no combustion, and consequently a car that will lose power, have worse fuel economy, and increased emissions. One of the most common problems with any fuel injected engine is that the injectors that bring the fuel to the combustion chamber can get clogged up. Removing fuel injectors and and cleaning them outside the engine is a tough job for a home mechanic. These are among the most popular and highest-rated fuel injector cleaners, so you can buy these products knowing that they have been tested and approved by other consumers just like you.įor more information on the best fuel injector cleaners, refer to our table of contents.Įverything You Need to Know About Fuel Injector Cleaners These products allow you to simply apply a fuel injector additive to your fuel tank, cleaning out the inner workings of your engine’s fuel system and reducing the chance that you’ll need to perform costly maintenance work sometime down the road.ĭrivers looking for fuel injector cleaners are spoiled by a huge amount of options, but we’ve made a list of the best fuel injector cleaners on the market today to make your buying decision easier.

Fuel injection systems are high-precision electro-mechanical systems with tight tolerances that operate under very high pressures, and all the fuel has to squeeze out of injectors with tiny outlets.Įven if you are careful about using the recommended fuel for your engine, contaminants can still make their way into your fuel system from the gas station’s underground tanks. If that happens, it might be time to treat your engine’s fuel system to a cleaning with the best fuel injector cleaner you can use. ![]() As time passes, your car might not accelerate as quickly as it once did the engine may not run as smoothly as you remember, or the fuel economy may dip-but everything else may work fine. ![]()
