It is rarely ever pleasurable to perceive an injector noise on your Dacia Duster 2. It is a noise that appears regularly, usually when you accelerate or your engine is idling. However, this symptom may be relating to multiple kind of concerns with your vehicle injectors. It may not be anything serious, but when a repeated noise arises, you have to be sure. Specifically since repairing your Dacia Duster 2’s injectors can be costly. That’s why our team decided to produce this content page in order to support you see more clearly, learn about the different possible failures and establish your issue. To do this, we will first look at the normal running and usefulness of the injectors in your Dacia Duster 2, then at the possible reasons from which an injector noise may come.injector-noise-dacia-duster-2

Functions of the injectors

Injectors are a very fundamental part of the operation of your engine motor. They were released to the modern vehicles 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 ability, 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 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 origins of a clicking or knocking noise based on the injectors of your Dacia Duster 2

Discovering injector noises on your Dacia Duster 2 may result from different locations, we will now center on the potential triggers of these. Generally, the common 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 stop them. If you perceive another clicking noise but it is not from your injectors, we encourage you to examine this content page about clicking noise on Dacia Duster 2 to find the reason.

The reasons for injector clicking or knocking noise Dacia Duster 2

A clicking or knocking noise from your injectors can be explained for different reasons. Indeed, the injectors of your Dacia Duster 2 have three main missions, to control the vaporisation of the fuel, i.e., to transform the liquid into “gas” during injection, to ease its combustion. Then, its task is to manage the air/fuel dosage and at last the homogeneity of the mixture, always with the target of improving combustion. If one of these three functions is altered, the main functionality 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 induce thoses knocking or clicking noises on your Dacia Duster 2. The main reason of these concerns generally comes from a particle that gets into the injectors. The precision of the injector being in the nanometer range, any possible blockage will inevitably cause a malfunction of the injector. If after verifying, this noise comes from another component of the engine of your Dacia Duster 2, have a look at this content page for more infos.

The effects of injector noise on Dacia Duster 2

Now that we have examined the different reasons for injector noise on your Dacia Duster 2, we will end by stating the possible end result 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 repercussions which can promptly 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 noticed by drivers is a significant 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 deteriorating one of your pistons or your engine. Poor combustion will promptly damage your cylinders or pistons and your engine may tighten.
Here are three little suggestions 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>
