It is hardly ever pleasurable to acknowledge an injector noise on your Lincoln MKX. It is a noise that happens frequently, usually when you accelerate or your engine is idling. However, this sign may be connected to several types of concerns with your vehicle injectors. It may not be anything severe, but when a persistent noise arises, you have to be sure. Specifically since replacing your Lincoln MKX’s injectors can be expensive. That’s why our team decided to prepare this article content in order to support you see more clearly, learn about the different plausible failures and determine your issue. To do this, we will first look at the normal functioning and usefulness of the injectors in your Lincoln MKX, then at the plausible causes from which an injector noise may come.
Functions of the injectors
Injectors are a very important element of the operation of your engine. They were introduced to the modern vehicles about 20 years ago. Before their introduction, more conventional carburettor-type intake systems were employed, which handled the intake of air and fuel into the engine cylinders. With the injectors, manufacturers now have the possibility, thanks to the injectors pump, to control electronically each stage of the intake process very precisely (quantity of fuel injected, air/fuel mixture) via the analysis of the data obtained from the various sensors equipping the vehicle (engine temperature, acceleration level, engine speed, etc.). Their aim 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 origins of a clicking or knocking noise based on the injectors of your Lincoln MKX
Discovering injector noises on your Lincoln MKX may originate from different locations, we will now look into the potential triggers of these. Generally, the usual noise of a faulty injector is of the snap type. Here are the different origins of these noises and the solutions to be implemented to stop them. If you acknowledge another clicking noise but it is not from your injectors, we advise you to examine this article content about clicking noise on Lincoln MKX to locate the trigger.
The causes for injector clicking or knocking noise Lincoln MKX
A clicking or knocking noise from your injectors can be explained for different causes. In fact, the injectors of your Lincoln MKX have three main missions, to control the vaporisation of the fuel, i.e., to transform the liquid into “gas” during injection, to facilitate its combustion. Then, its objective is to control the air/fuel dosage and finally the homogeneity of the mixture, always with the target of improving combustion. If one of these three functions is modified, the main role of the injectors will be disrupted and this will lead to poor combustion. This bad combustion will be a violent explosion in the cylinders due to bad timing, or a bad quantity of mixture or finally an inhomogeneous mixture and will provoke thoses knocking or clicking noises on your Lincoln MKX. The main trigger of these problems usually comes from a particle that gets into the injectors. The accuracy of the injector being in the nanometer range, any possible blockage will inevitably end in a malfunction of the injector. If after checking, this noise comes from another element of the engine of your Lincoln MKX, read this article content for more infos.
The repercussions of injector noise on Lincoln MKX
Now that we have examined the diverse causes for injector noise on your Lincoln MKX, we will end by stating the possible end result of malfunctioning one or more of your injectors. Whether only one is blocked, or broken, or your entire fuel rail is involved, you cannot escape these effects which can almost instantly become major….
First, you risk destroying your exhaust unit 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 basic consequences felt by drivers is a serious loss of power. In fact, if your engine is running on 3 out of 4 cylinders for example, you will surely have a loss of power
Finally, you risk deteriorating one of your pistons or your engine. Poor combustion will almost instantly damage your cylinders or pistons and your engine may tighten.
Here are three little suggestions 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>
