It is hardly ever pleasurable to acknowledge an injector noise on your Lincoln MKZ. It is a noise that happens repeatedly, usually when you accelerate or your engine is idling. However, this sign may be connected to several types of complications with your car injectors. It may not be anything serious, but when a recurrent noise arises, you have to be sure. Specifically since fixing your Lincoln MKZ’s injectors can be expensive. That’s why our team chose to compose this content page in order to help you see more clearly, learn about the different plausible failures and distinguish your issue. To do this, we will first look at the normal running and usefulness of the injectors in your Lincoln MKZ, then at the plausible reasons from which an injector noise may come.injector-noise-lincoln-mkz

Purposes of the injectors

Injectors are a very fundamental part of the operation of your engine unit. They were introduced to the modern automobiles about 20 years ago. Before their appearance, 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 compiled from the various sensors equipping the car (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 obtain the best possible combustion in the cylinders.

The different triggers of a clicking or knocking noise caused by the injectors of your Lincoln MKZ

Hearing injector noises on your Lincoln MKZ may come from different origins, we will now focus on the potential triggers of these. In most cases, the regular noise of a faulty injector is of the snap type. Here are the several origins of these noises and the solutions to be implemented to eliminate them. If you acknowledge another clicking noise but it is not from your injectors, we encourage you to go through this content page about clicking noise on Lincoln MKZ to locate the trigger.

The causes for injector clicking or knocking noise Lincoln MKZ

A clicking or knocking noise from your injectors can be explained for different causes. Indeed, the injectors of your Lincoln MKZ have three main tasks, to control the vaporisation of the fuel, i.e., to transform the liquid into “gas” during injection, to ease its combustion. Then, its objective is to control the air/fuel dosage and finally the homogeneity of the mixture, always with the aim of improving combustion. If one of these three characteristics is altered, 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 because 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 MKZ. The main trigger of these problems in most cases comes from a particle that gets into the injectors. The precision of the injector being in the nanometer range, any possible obstruction will inevitably result in a malfunction of the injector. If after verifying, this noise comes from another component of the engine of your Lincoln MKZ, read this content page for more informations.

The effects of injector noise on Lincoln MKZ

Now that we have reviewed the diverse reasons for injector noise on your Lincoln MKZ, we will end by stating the possible effects of malfunctioning one or more of your injectors. Whether only one is obstructed, or broken, or your entire fuel rail is involved, you cannot escape these consequences which can quickly become critical….
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 common effects felt by drivers is a distinctive loss of power. Indeed, 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 quickly affect your cylinders or pistons and your engine may tighten.
Here are three little tips to limit the risks connected with 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>
