Hi Kerrville motorists. Let’s talk fuel injectors. 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 truck 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 and 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 efficiency and loss of engine performance for Kerrville car owners.
So it’s to Kerrville drivers’ advantage to keep their 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 fuel companies also deliver a more consistent quality of fuel to Kerrville auto owners than do bargain Luling area service stations.
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.
Kerrville auto owners should check their owner’s manual to find out how often they should change their 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 between Kerrville, Ingram and Lockhart , your filter will need to be changed more often.
You can also purchase cleaners at Texas Express Lube & Auto 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 Texas Express Lube & Auto in Kerrville that will result in better fuel efficiency and improved vehicle performance.
Good car care will prevent serious damage to your fuel injector system. And this is one system that you want to keep in perfect condition.
