It is never pleasurable to acknowledge an injector noise on your Dacia Dokker. It is a noise that comes up repeatedly, usually when you accelerate or your engine is idling. However, this symptom may be linked to several types of complications with your vehicle injectors. It may not be anything major, but when a frequent noise happens, you have to be sure. Most importantly since repairing your Dacia Dokker’s injectors can be costly. That’s why our team decided to compose this content in order to help you see more clearly, learn about the different plausible failures and identify your issue. To do this, we will first look at the normal functioning and usefulness of the injectors in your Dacia Dokker, then at the plausible causes from which an injector noise may come.
Attributes of the injectors
Injectors are a very vital part of the operation of your engine motor. They were brought in to the modern cars 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 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 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 reasons of a clicking or knocking noise based on the injectors of your Dacia Dokker
Hearing injector noises on your Dacia Dokker may result from different locations, we will now center on the potential triggers of these. In general, the common noise of a faulty injector is of the snap type. Here are the several sources of these noises and the solutions to be put into practice to stop them. If you acknowledge another clicking noise but it is not from your injectors, we encourage you to examine this content about clicking noise on Dacia Dokker to locate the cause.
The reasons for injector clicking or knocking noise Dacia Dokker
A clicking or knocking noise from your injectors can be explained for different reasons. In fact, the injectors of your Dacia Dokker have three main missions, to manage the vaporisation of the fuel, i.e., to transform the liquid into “gas” during injection, to ease its combustion. Then, its goal is to control the air/fuel dosage and at last the homogeneity of the mixture, always with the aim of improving combustion. If one of these three characteristics 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 resulting from bad timing, or a bad quantity of mixture or finally an inhomogeneous mixture and will trigger thoses knocking or clicking noises on your Dacia Dokker. 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 produce a malfunction of the injector. If after checking, this noise comes from another element of the engine of your Dacia Dokker, read this content for more informations.
The effects of injector noise on Dacia Dokker
Now that we have reviewed the several reasons for injector noise on your Dacia Dokker, 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 side effects which can fairly quickly become critical….
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 experienced by drivers is a serious 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 degrading one of your pistons or your engine. Poor combustion will fairly quickly affect your cylinders or pistons and your engine may tighten.
Here are three little recommendations to limit the risks connected 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>
