It is rarely ever relaxing to notice an injector noise on your Ds Ds 4. It is a noise that appears repeatedly, usually when you accelerate or your engine is idling. However, this symptom may be linked to different kind of complications with your car injectors. It may not be anything serious, but when a persistent noise comes out, you have to be sure. Especially since repairing your Ds Ds 4’s injectors can be costly. That’s why our team decided to write this article content in order to support you see more clearly, learn about the different plausible failures and determine your issue. To do this, we will first look at the normal running and usefulness of the injectors in your Ds Ds 4, then at the plausible causes from which an injector noise may come.injector-noise-ds-ds-4

Functions of the injectors

Injectors are a very useful element of the operation of your engine motor. They were introduced to the modern automobiles about 20 years ago. Before their arrival, 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 possibility, 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 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 get the best possible combustion in the cylinders.

The different reasons of a clicking or knocking noise caused by the injectors of your Ds Ds 4

Listening injector noises on your Ds Ds 4 may result from different sources, we will now center on the potential causes 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 applied to stop them. If you notice another clicking noise but it is not from your injectors, we suggest you to read this article content about clicking noise on Ds Ds 4 to find the cause.

The causes for injector clicking or knocking noise Ds Ds 4

A clicking or knocking noise from your injectors can be explained for different causes. Indeed, the injectors of your Ds Ds 4 have three main missions, to manage the vaporisation of the fuel, i.e., to convert the liquid into “gas” during injection, to ease its combustion. Then, its mission 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 tasks is altered, 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 resulting from bad timing, or a bad quantity of mixture or finally an inhomogeneous mixture and will induce thoses knocking or clicking noises on your Ds Ds 4. The main cause of these concerns usually comes from a particle that gets into the injectors. The precision of the injector being in the nanometer range, any possible obstruction will inevitably result in a malfunction of the injector.

The effects of injector noise on Ds Ds 4

Now that we have examined the diverse reasons for injector noise on your Ds Ds 4, 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 consequences which can fairly quickly 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 known effects experienced 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 fairly quickly damage your cylinders or pistons and your engine may tighten.
Here are three little suggestions to limit the risks associated 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 changing your diesel fuel filter regularly>
