Before knowing more about the problems that dirty fuel injectors can lead to, let’s discuss about what they are. These injectors are essentially small devices meant to force fuel via a nozzle over the pistons in a uniform spray. An even pattern of spray ensures efficient combustion of the fuel. With passage of time, however, dirty fuel or aging can allow carbon to accumulate on the small devices, thereby disturbing the spray and decreasing fuel economy. At times, the carbon buildup might even block out the spray entirely and cause the injectors to malfunction.
Thus, instead of having the fuel injectors of your car replaced once they become redundant, you can get them checked regularly after every 30,000 or 40,000 miles. Doing so would help you to do more than just save money on gas. You will also be able to avoid costly repairs when the fuel burns efficiently. A good fuel injection service can even silence carbon knocks, which are knocking noises produced by the engine because of excessive carbon accumulation rubbing against the internal components. If you are lucky enough to visit a shop where they use a high quality cleaning solution, you may expect the liquid to eliminate carbon deposits in the valve and the fuel tank also.
So what are you waiting for? If you have an old car that consumes too much fuel, have its injector checked properly by a reliable auto mechanic.
