It is rarely ever pleasant to listen to an injector noise on your Renault Latitude. It is a noise that comes up regularly, usually when you accelerate or your engine is idling. However, this symptom may be connected to several sort of trouble with your vehicle injectors. It may not be anything serious, but when a persistent noise happens, you have to be sure. Especially since replacing your Renault Latitude’s injectors can be costly. That’s why our team chose to produce this content page in order to help you see more clearly, learn about the different plausible failures and determine your problem. To do this, we will first look at the normal running and usefulness of the injectors in your Renault Latitude, then at the plausible reasons from which an injector noise may come.injector-noise-renault-latitude

Attributes of the injectors

Injectors are a very important component of the operation of your engine motor. 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 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 vehicle (engine temperature, acceleration level, engine speed, etc.). Their goal 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 based on the injectors of your Renault Latitude

Listening injector noises on your Renault Latitude may come from different sources, we will now focus on the potential causes of these. In general, 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 stop them. If you listen to another clicking noise but it is not from your injectors, we encourage you to examine this content page about clicking noise on Renault Latitude to locate the trigger.

The reasons for injector clicking or knocking noise Renault Latitude

A clicking or knocking noise from your injectors can be explained for different reasons. Indeed, the injectors of your Renault Latitude have three main missions, to manage the vaporisation of the fuel, i.e., to convert the liquid into “gas” during injection, to facilitate its combustion. Then, its objective is to manage the air/fuel dosage and at last the homogeneity of the mixture, always with the aim of improving combustion. If one of these three tasks 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 trigger thoses knocking or clicking noises on your Renault Latitude. The main trigger of these situations commonly originates from a particle that gets into the injectors. The accuracy of the injector being in the nanometer range, any possible obstruction will inevitably produce a malfunction of the injector. If after verifying, this noise originates from another part of the engine of your Renault Latitude, check this content page for more infos.

The effects of injector noise on Renault Latitude

Now that we have analyzed the different causes for injector noise on your Renault Latitude, we will end by stating the possible effects of malfunctioning one or more of your injectors. Whether only one is clogged, 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 repercussions felt 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 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 swapping your diesel fuel filter regularly>
