A fuel injector is a valve that delivers fuel to a vehicle's engine. It has to deliver the precise amount of fuel to precisely the right place, precisely when the engine needs it. The fuel also has to be mixed with air before it can burn in the engine.

Fuel injectors are engineered to spray fuel in a specific pattern into the engine. (The pattern varies by engine type and design.) In order to achieve these spray patterns, the fuel must be pressurized.

The pressure in a fuel injection system varies depending on its type. Many gasoline engines use port injection systems, which operate with a pressure of 60 pounds per square inch. Newer direct injection systems operate at 10 to 30 times that pressure. Some diesel passenger vehicles have fuel injectors that operate at 30,000 pounds or more per square inch.

Vehicles have one fuel injector for each cylinder in the engine. Your vehicle's control computer constantly monitors the engine and various sensors in the vehicle.  It also adjusts the fuel injectors accordingly so that they can deliver the proper amount of fuel to the engine. As you can see, fuel injectors are a sophisticated and vital part of your vehicle's engine.

Because fuel injectors are such precision instruments, dirt and contaminants are a serious detriment to their performance. When an injector gets gummed up, it affects the pressure, pattern and timing of the fuel delivery. The result is a decrease in fuel economy and loss of engine performance.

So it's important to keep your fuel injectors clean. That starts with keeping the fuel in your tank clean. High-quality fuel contains detergents and additives that help clean your engine. Brand-name Missouri fuel companies also deliver a more consistent quality of fuel than do bargain stations in the Jackson area.

The second way to keep your injectors clean is to keep your fuel filter clean. This filter screens dirt and rust out of the fuel as it travels from the tank to the engine. If the filter clogs up, fuel will bypass it and carry its load of dirt into the engine.

Check your owner's manual or ask the pros at Charlie's Fast Lube Jackson in Jackson to find out how often you should change your fuel filter. This should be part of your regular preventive maintenance. Also, remember that if you use bargain-brand or low-grade fuels, or if you drive an older vehicle, your filter will need to be changed more often.

You can also purchase cleaners that will protect your fuel injectors. These cleaners are added to the fuel tank. They work best at preventing build-up in your fuel injectors and can clean up small amounts of carbon, gum and varnish. But they won't be able to clean a fully gummed-up injector. Read the labels before using any of these products for full directions on their use.

If your fuel injectors are gummed up, you can get a professional deep cleaning service at Charlie's Fast Lube Jackson in Jackson that will result in better fuel economy and improved vehicle performance.

Good vehicle care will prevent serious damage to your fuel injector system. And this is one system that you want to keep in perfect condition.
