It is never pleasant to listen to an injector noise on your Land Rover Discovery Sport. It is a noise that appears continually, usually when you accelerate or your engine is idling. However, this indicator may be connected to different types of trouble with your vehicle injectors. It may not be anything serious, but when a continuing noise appears, you have to be sure. Especially since fixing your Land Rover Discovery Sport’s injectors can be expensive. That’s why our team chose to produce this content page in order to help you see more clearly, learn about the different conceivable failures and identify your issue. To do this, we will first look at the normal running and usefulness of the injectors in your Land Rover Discovery Sport, then at the conceivable reasons from which an injector noise may come.injector-noise-land-rover-discovery-sport

Purposes of the injectors

Injectors are a very vital element of the operation of your engine unit. They were launched to the modern automobiles 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 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 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 coming from the injectors of your Land Rover Discovery Sport

Discovering injector noises on your Land Rover Discovery Sport may originate from different origins, we will now focus on the potential triggers of these. Generally, the common noise of a faulty injector is of the snap type. Here are the different sources of these noises and the solutions to be put into practice to eliminate 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 Land Rover Discovery Sport to discover the cause.

The explanations for injector clicking or knocking noise Land Rover Discovery Sport

A clicking or knocking noise from your injectors can be explained for different explanations. Indeed, the injectors of your Land Rover Discovery Sport have three main tasks, to control the vaporisation of the fuel, i.e., to transform the liquid into “gas” during injection, to ease its combustion. Then, its objective is to deal with the air/fuel dosage and at last the homogeneity of the mixture, always with the target of improving combustion. If one of these three functions is altered, the main functionality of the injectors will be disturbed and this will lead to poor combustion. This bad combustion will be a violent explosion in the cylinders because of bad timing, or a bad quantity of mixture or finally an inhomogeneous mixture and will trigger thoses knocking or clicking noises on your Land Rover Discovery Sport. The main cause of these trouble in most cases originates from a particle that gets into the injectors. The accuracy of the injector being in the nanometer range, any possible blockage will inevitably end in a malfunction of the injector.

The repercussions of injector noise on Land Rover Discovery Sport

Now that we have analyzed the different causes for injector noise on your Land Rover Discovery Sport, 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 side effects which can almost instantly become major….
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 consequences noticed by drivers is a significant loss of power. Indeed, 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 almost instantly damage your cylinders or pistons and your engine may tighten.
Here are three little tips 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>
