It is never pleasurable to perceive an injector noise on your Dacia Sandero 2. It is a noise that arises continually, usually when you accelerate or your engine is idling. However, this sign may be relating to several kind of complications with your car injectors. It may not be anything major, but when a continuing noise appears, you have to be sure. Especially since repairing your Dacia Sandero 2’s injectors can be expensive. That’s why our team decided to create this content page in order to support you see more clearly, learn about the different plausible failures and establish your issue. To do this, we will first look at the normal functioning and usefulness of the injectors in your Dacia Sandero 2, then at the plausible reasons from which an injector noise may come.injector-noise-dacia-sandero-2

Purposes of the injectors

Injectors are a very significant component of the operation of your engine unit. They were introduced 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 opportunity, 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 car (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 obtain the best possible combustion in the cylinders.

The different causes of a clicking or knocking noise caused by the injectors of your Dacia Sandero 2

Experiencing injector noises on your Dacia Sandero 2 may come from different origins, we will now concentrate on the potential causes of these. In most cases, the typical noise of a faulty injector is of the snap type. Here are the several origins of these noises and the solutions to be adopted to prevent them. If you perceive another clicking noise but it is not from your injectors, we advise you to read this content page about clicking noise on Dacia Sandero 2 to discover the trigger.

The causes for injector clicking or knocking noise Dacia Sandero 2

A clicking or knocking noise from your injectors can be explained for different causes. Indeed, the injectors of your Dacia Sandero 2 have three main tasks, to manage the vaporisation of the fuel, i.e., to convert the liquid into “gas” during injection, to facilitate its combustion. Then, its objective 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 characteristics is altered, the main purpose of the injectors will be disturbed 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 Sandero 2. The main trigger of these situations commonly originates from a particle that gets into the injectors. The accuracy of the injector being in the nanometer range, any possible blockage will inevitably lead to a malfunction of the injector. If after checking, this noise originates from another part of the engine of your Dacia Sandero 2, have a look at this content page for more infos.

The repercussions of injector noise on Dacia Sandero 2

Now that we have reviewed the different causes for injector noise on your Dacia Sandero 2, 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 fairly quickly become major….
First, you risk destroying your exhaust system 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 effects experienced by drivers is a distinctive loss of power. Indeed, if your engine is running on 3 out of 4 cylinders for example, you will obviously have a loss of power
Finally, you risk deteriorating one of your pistons or your engine. Poor combustion will fairly quickly damage your cylinders or pistons and your engine may tighten.
Here are three little recommendations 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>
