Without it, the air/fuel mixture becomes lean, which can cause severe engine damage and a failure in turbo drive systems.ģ. When a car goes turbo, it needs all the fuel the injectors can provide. Turbo – Blocked or dirty injectors can cause catastrophic engine failure in turbo charged cars. This is when either the amount of fuel or the amount of air becomes off ratio, making the fuel harder to ignite and combustion difficult.Ģ. Restricted – If a fuel injector becomes restricted from clogging, even if it is as little as 10% of the entire aperture, the air/fuel ratio in the engine can become lean, leading to what is known as a lean misfire. The list below describes some of the most common signs and symptoms.ġ. There are many signs which can indicate an issue with your fuel injectors, be it that they are clogged, damaged, or faulty. A fully-working fuel injector should not only provide the engine with fuel but also deliver this at the right pressure, angle, and spray pattern. By using air data given to it by the mass air flow sensor, it calculates the correct amount of fuel to provide. The injectors are electronically-controlled by the onboard computer. The sole purpose of a fuel injector is to inject the correct amount of fuel into the engine to create the optimal air/fuel ratio required for easy ignition. In this article, we will take a closer look at your car’s fuel injectors, discus what they are, look at some signs which indicate they could be failing, and talk about why seeking maintenance is essential. Low maintenance standards can severely impact the longevity of your car and rack up costly repair bills. Yet still, many of us neglect key maintenance practices for our vehicles. We use them day in and day out and would be really stuck if anything should happen. It’s safe to say that in the 21st century, we simply could not live without our cars.
