It is never enjoyable to listen to an injector noise on your Dacia Logan. It is a noise that happens regularly, usually when you accelerate or your engine is idling. However, this indicator may be linked to multiple sort of complications with your automobile injectors. It may not be anything major, but when a recurrent noise comes out, you have to be sure. Specifically since repairing your Dacia Logan’s injectors can be expensive. That’s why our team chose to create this content page in order to help you see more clearly, learn about the different conceivable failures and determine your trouble. To do this, we will first look at the normal function and usefulness of the injectors in your Dacia Logan, then at the conceivable causes from which an injector noise may come.injector-noise-dacia-logan

Attributes of the injectors

Injectors are a very useful part of the operation of your engine unit. They were introduced to the modern vehicles about 20 years ago. Before their introduction, more conventional carburettor-type intake systems were used, 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 received from the various sensors equipping the automobile (engine temperature, acceleration level, engine speed, etc.). Their aim 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 triggers of a clicking or knocking noise caused by the injectors of your Dacia Logan

Listening injector noises on your Dacia Logan may result from different locations, we will now concentrate on the potential triggers of these. Generally, the typical 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 get rid of them. If you listen to another clicking noise but it is not from your injectors, we encourage you to go through this content page about clicking noise on Dacia Logan to discover the trigger.

The explanations for injector clicking or knocking noise Dacia Logan

A clicking or knocking noise from your injectors can be explained for different explanations. In fact, the injectors of your Dacia Logan have three main missions, to manage the vaporisation of the fuel, i.e., to transform the liquid into “gas” during injection, to facilitate its combustion. Then, its goal is to deal with the air/fuel dosage and finally the homogeneity of the mixture, always with the objective of improving combustion. If one of these three functions is modified, the main role of the injectors will be disrupted and this will lead to poor combustion. This bad combustion will be a violent explosion in the cylinders due to bad timing, or a bad quantity of mixture or finally an inhomogeneous mixture and will provoke thoses knocking or clicking noises on your Dacia Logan. The main trigger of these trouble 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 end in a malfunction of the injector.

The side effects of injector noise on Dacia Logan

Now that we have reviewed the several causes for injector noise on your Dacia Logan, we will end by stating the possible consequences of malfunctioning one or more of your injectors. Whether only one is obstructed, or broken, or your entire fuel rail is involved, you cannot escape these repercussions which can fairly quickly become severe….
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 known effects experienced by drivers is a severe loss of power. In fact, if your engine is running on 3 out of 4 cylinders for example, you will surely 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 suggestions to limit the risks linked 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 swapping your diesel fuel filter regularly>
