It is hardly ever pleasant to experience an injector noise on your Jeep Liberty. It is a noise that comes up continually, usually when you accelerate or your engine is idling. However, this symptom may be related to several types of trouble with your car injectors. It may not be anything severe, but when a persistent noise happens, you have to be sure. Most importantly since replacing your Jeep Liberty’s injectors can be expensive. That’s why our team chose to write this article content in order to help you see more clearly, learn about the different plausible failures and distinguish your trouble. To do this, we will first look at the normal functioning and usefulness of the injectors in your Jeep Liberty, then at the plausible causes from which an injector noise may come.
Functions of the injectors
Injectors are a very vital element of the operation of your engine unit. They were brought in to the modern cars about 20 years ago. Before their arrival, 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 accurately (quantity of fuel injected, air/fuel mixture) via the analysis of the data accumulated from the various sensors equipping the car (engine temperature, acceleration level, engine speed, etc.). Their objective 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 triggers of a clicking or knocking noise based on the injectors of your Jeep Liberty
Finding out injector noises on your Jeep Liberty may result from different sources, we will now concentrate on the potential causes of these. In general, 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 put into practice to prevent them. If you experience another clicking noise but it is not from your injectors, we advise you to read this article content about clicking noise on Jeep Liberty to discover the reason.
The explanations for injector clicking or knocking noise Jeep Liberty
A clicking or knocking noise from your injectors can be justified by different explanations. Indeed, the injectors of your Jeep Liberty have three main missions, to manage the vaporisation of the fuel, i.e., to convert the liquid into “gas” during injection, to facilitate its combustion. Then, its mission is to manage the air/fuel dosage and at last the homogeneity of the mixture, always with the aim of improving combustion. If one of these three characteristics is modified, the main functionality 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 provoke thoses knocking or clicking noises on your Jeep Liberty. The main reason of these problems usually originates from a particle that gets into the injectors. The accuracy of the injector being in the nanometer range, any possible obstruction will inevitably end up in a malfunction of the injector.

The effects of injector noise on Jeep Liberty
Now that we have reviewed the several causes for injector noise on your Jeep Liberty, 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 effects which can fairly quickly 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 common effects experienced by drivers is a serious loss of power. Indeed, if your engine is running on 3 out of 4 cylinders for example, you will undoubtedly have a loss of power
Finally, you risk deteriorating one of your pistons or your engine. Poor combustion will fairly quickly harm your cylinders or pistons and your engine may tighten.
Here are three little tips to limit the risks relating 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 changing your diesel fuel filter regularly>
