The main purpose of electronic fuel injection systems in all the latest car models is to reduce the fuel consumption. Within a very short period of time, vehicles with fuel injection systems have become quite popular because of their superior performance; they even replaced the old model carburetor engine vehicles.
The main function of an electronic fuel injection system is to push the fuel into the engine. Fuel injector is an important component that uniformly sprays fuel into the combustion chamber. The same component because of its location is susceptible to clogging with unburned additives. A clogged fuel injector cannot deliver the required amount of fuel to the engine, affecting its performance. Thus, regular maintenance of fuel injector is important to achieve maximum engine performance.
In this article, we will discuss about the role and importance of fuel injectors; we will also learn few tips to maintain them properly.
Importance of maintaining clean fuel injectors Here are the reasons for maintaining clean fuel injectors.
Efficient combustion: Sufficient amount of fuel and correct spray pattern are highly essential for efficient combustion of fuel. A clogged injector not only restricts the fuel to flow, but also disrupts the spray pattern. The opening of the fuel injector is very small; even a little buildup of deposits can affect its functionality. Lean misfire, starting trouble and loss of power are some of the symptoms of a clogged injector. To support clean and efficient combustion, injectors need to be cleaned and maintained periodically.
Proper engine performance: A clogged fuel injector leads to many issues that can negatively affect the engine’s performance. Due to irregular fuel supply, the engine fluctuates between low and high rpms and thus delivers chunks of power. This results in abrupt engine power. Similarly, when the supply of fuel to the engine stops abruptly, it leads to misfires. Periodic maintenance of fuel injector gives maximum power to the engine and ensures its reliability and longevity.
Good mileage: Whenever the fuel injector gets clogged, the control module of the engine tries to adjust the fuel flow which sometimes leads to excess fuel consumption. Loss of power while accelerating the vehicle, engine misfire and rough idling along with sputtering noise are some signs of a leaky or faulty fuel injector. So, in order to get good mileage, a clean fuel injector is highly essential.
Reduced emissions: A healthy fuel injector often produces a cone shaped mist of fuel vapor. Whereas a clogged fuel injector creates streamers of liquid fuel that vaporizes and burns poorly. This results in increased emissions. Thus to reduce emissions, you should have a clean fuel injector in your vehicle.
Having understood the benefits of having a clean fuel injector, let us now see what precautions you need to take to maintain it clean.
Tips to keep fuel injectors clean
Use high quality fuel: One of the best ways to maintain clean fuel injectors is to use high quality gasoline. Different brands offer different blends that are formulated to reduce/prevent fuel debris that is build up in the injectors. So, instead of going for low quality gasoline and adding additives to it, you can buy high quality gasoline blends that have detergents which prevent the deposits.
Regularly clean fuel injectors: Clean fuel injectors help the engine achieve peak performance, improve fuel economy and reduce emissions. Compared to low mileage vehicles, high mileage engines and those vehicles that are used quite frequently, require regular injector cleaning. In general, injectors should be cleaned every 25,000 to 30,000 miles in order to make them work efficiently.
Use branded fuel injectors: Besides taking all the above precautions, it is very important to use branded fuel injectors instead of less reliable brands. They may cost you a few more bucks, but they are really important to reduce the negative effects of a low quality fuel injector on the engine’s performance.
