It is never relaxing to experience an injector noise on your Dacia Lodgy. It is a noise that comes up frequently, usually when you accelerate or your engine is idling. However, this indicator may be connected to multiple types of problems with your car injectors. It may not be anything major, but when a continuing noise arises, you have to be sure. Especially since replacing your Dacia Lodgy’s injectors can be expensive. That’s why our team decided to write this article in order to help you see more clearly, learn about the different possible failures and establish your trouble. To do this, we will first look at the normal functioning and usefulness of the injectors in your Dacia Lodgy, then at the possible reasons from which an injector noise may come.
Functions of the injectors
Injectors are a very useful element of the operation of your engine. They were released to the modern cars about 20 years ago. Before their arrival, 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 precisely (quantity of fuel injected, air/fuel mixture) via the analysis of the data collected 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 origins of a clicking or knocking noise caused by the injectors of your Dacia Lodgy
Discovering injector noises on your Dacia Lodgy may result from different sources, we will now focus on the potential causes of these. Generally, the usual noise of a faulty injector is of the snap type. Here are the different sources of these noises and the solutions to be applied to get rid of them. If you experience another clicking noise but it is not from your injectors, we encourage you to examine this article about clicking noise on Dacia Lodgy to discover the cause.
The explanations for injector clicking or knocking noise Dacia Lodgy
A clicking or knocking noise from your injectors can be justified by different explanations. Indeed, the injectors of your Dacia Lodgy have three main missions, to control the vaporisation of the fuel, i.e., to convert the liquid into “gas” during injection, to facilitate its combustion. Then, its goal is to control the air/fuel dosage and finally the homogeneity of the mixture, always with the objective of improving combustion. If one of these three features 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 resulting from bad timing, or a bad quantity of mixture or finally an inhomogeneous mixture and will provoke thoses knocking or clicking noises on your Dacia Lodgy. The main cause of these situations in most cases comes from a particle that gets into the injectors. The accuracy of the injector being in the nanometer range, any possible blockage will inevitably result in a malfunction of the injector.

The effects of injector noise on Dacia Lodgy
Now that we have reviewed the diverse reasons for injector noise on your Dacia Lodgy, we will end by stating the possible effects 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 effects which can fairly quickly become critical….
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 consequences noticed by drivers is a serious 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 affect 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 changing your diesel fuel filter regularly>
