It is hardly ever enjoyable to perceive an injector noise on your Lincoln MKC. It is a noise that appears repeatedly, usually when you accelerate or your engine is idling. However, this sign may be connected to several sort of complications with your vehicle injectors. It may not be anything major, but when a persistent noise appears, you have to be sure. Most importantly since replacing your Lincoln MKC’s injectors can be expensive. That’s why our team chose to prepare this article content in order to support you see more clearly, learn about the different possible failures and distinguish your problem. To do this, we will first look at the normal function and usefulness of the injectors in your Lincoln MKC, then at the possible causes from which an injector noise may come.
Purposes of the injectors
Injectors are a very fundamental element of the operation of your engine unit. They were brought in to the modern vehicles about 20 years ago. Before their appearance, more conventional carburettor-type intake systems were used, which handled the intake of air and fuel into the engine cylinders. With the injectors, manufacturers now have the ability, thanks to the injectors pump, to control electronically each stage of the intake process very accurately (quantity of fuel injected, air/fuel mixture) via the analysis of the data accumulated from the various sensors equipping the vehicle (engine temperature, acceleration level, engine speed, etc.). Their goal is therefore to inject under high pressure a precise quantity of an air/fuel mixture at a perfect timing to get the best possible combustion in the cylinders.
The different reasons of a clicking or knocking noise caused by the injectors of your Lincoln MKC
Hearing injector noises on your Lincoln MKC may result from different locations, we will now look into the potential causes of these. Generally, the typical noise of a faulty injector is of the snap type. Here are the several sources of these noises and the solutions to be implemented to eliminate them. If you perceive another clicking noise but it is not from your injectors, we encourage you to browse this article content about clicking noise on Lincoln MKC to locate the cause.
The reasons for injector clicking or knocking noise Lincoln MKC
A clicking or knocking noise from your injectors can be explained for different reasons. Indeed, the injectors of your Lincoln MKC have three main missions, to manage the vaporisation of the fuel, i.e., to transform the liquid into “gas” during injection, to ease its combustion. Then, its goal is to manage the air/fuel dosage and finally the homogeneity of the mixture, always with the goal of improving combustion. If one of these three characteristics is altered, the main role of the injectors will be disturbed and this will lead to poor combustion. This bad combustion will be a violent explosion in the cylinders as a consequence of bad timing, or a bad quantity of mixture or finally an inhomogeneous mixture and will trigger thoses knocking or clicking noises on your Lincoln MKC. The main cause of these trouble usually originates from a particle that gets into the injectors. The accuracy of the injector being in the nanometer range, any possible blockage will inevitably end up in a malfunction of the injector. If after checking, this noise originates from another element of the engine of your Lincoln MKC, have a look at this article content for more infos.
The repercussions of injector noise on Lincoln MKC
Now that we have analyzed the several causes for injector noise on your Lincoln MKC, we will end by stating the possible consequences of malfunctioning one or more of your injectors. Whether only one is clogged, or broken, or your entire fuel rail is involved, you cannot escape these repercussions which can almost instantly become major….
First, you risk destroying your exhaust system in the long run, because the unburned fuel residues that will end up in your exhaust system can corrode the metal in it.
One of the most known consequences noticed by drivers is a severe loss of power. Indeed, if your engine is running on 3 out of 4 cylinders for example, you will inevitably have a loss of power
Finally, you risk degrading one of your pistons or your engine. Poor combustion will almost instantly affect your cylinders or pistons and your engine may tighten.
Here are three little recommendations to limit the risks connected to your injectors and protect you from engine failure:
- Do not drive at the bottom of the tank, as you may absorb impurities
- Use quality fuel
- Think of swapping your diesel fuel filter regularly>
