Benefits of the injectors

Injectors are a very significant part of the operation of your engine unit. They were released 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 accurately (quantity of fuel injected, air/fuel mixture) via the analysis of the data accumulated 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 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

Hearing injector noises on your Dacia Sandero may originate from different origins, we will now focus on the potential causes of these. In most cases, the typical noise of a faulty injector is of the snap type. Here are the different origins of these noises and the solutions to be used to stop them. If you acknowledge another clicking noise but it is not from your injectors, we recommend you to go through this article content about clicking noise on Dacia Sandero to locate the cause.

The reasons for injector clicking or knocking noise Dacia Sandero

A clicking or knocking noise from your injectors can be explained for different reasons. Indeed, the injectors of your Dacia Sandero 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 task is to control the air/fuel dosage and at last the homogeneity of the mixture, always with the goal of improving combustion. If one of these three features is altered, 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 trigger thoses knocking or clicking noises on your Dacia Sandero. The main cause of these trouble 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 lead to a malfunction of the injector.

The consequences of injector noise on Dacia Sandero

Now that we have reviewed the several causes for injector noise on your Dacia Sandero, we will end by stating the possible effects 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 almost instantly become severe….
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 consequences noticed by drivers is a distinctive 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 almost instantly harm your cylinders or pistons and your engine may tighten.
Here are three little recommendations 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>
