That’s why our team chose to produce this content in order to support you see more clearly, learn about the different possible failures and determine your problem. To do this, we will first look at the normal functioning and usefulness of the injectors in your Jeep Renegade, then at the possible triggers from which an injector noise may come.injector-noise-jeep-renegade

Functions of the injectors

Injectors are a very fundamental part of the operation of your engine motor. They were brought in to the modern automobiles 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 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 collected from the various sensors equipping the vehicle (engine temperature, acceleration level, engine speed, etc.). Their purpose 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 coming from the injectors of your Jeep Renegade

Finding out injector noises on your Jeep Renegade may result from different sources, we will now focus on the potential causes of these. In most cases, the usual noise of a faulty injector is of the snap type. Here are the several sources of these noises and the solutions to be applied to eliminate them. If you hear another clicking noise but it is not from your injectors, we encourage you to go through this content about clicking noise on Jeep Renegade to locate the reason.

The reasons for injector clicking or knocking noise Jeep Renegade

A clicking or knocking noise from your injectors can be justified by different reasons. In fact, the injectors of your Jeep Renegade have three main tasks, 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 deal with 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 purpose of the injectors will be disrupted and this will lead to poor combustion. This bad combustion will be a violent explosion in the cylinders resulting from bad timing, or a bad quantity of mixture or finally an inhomogeneous mixture and will trigger thoses knocking or clicking noises on your Jeep Renegade. The main reason of these trouble generally originates from a particle that gets into the injectors. The precision of the injector being in the nanometer range, any possible blockage will inevitably lead to a malfunction of the injector. If after verifying, this noise originates from another element of the engine of your Jeep Renegade, read this content for more informations.

The side effects of injector noise on Jeep Renegade

Now that we have reviewed the several reasons for injector noise on your Jeep Renegade, we will end by stating the possible consequences of malfunctioning one or more of your injectors. Whether only one is obstructed, or damaged, or your entire fuel rail is involved, you cannot escape these side 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 common repercussions noticed by drivers is a distinctive loss of power. In fact, if your engine is running on 3 out of 4 cylinders for example, you will undoubtedly have a loss of power
Finally, you risk degrading one of your pistons or your engine. Poor combustion will almost instantly harm 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 changing your diesel fuel filter regularly>
