It is never enjoyable to notice an injector noise on your Land Rover Discovery. It is a noise that appears repeatedly, usually when you accelerate or your engine is idling. However, this warning sign may be connected to several kind of trouble with your vehicle injectors. It may not be anything serious, but when a continuing noise comes out, you have to be sure. Especially since replacing your Land Rover Discovery’s injectors can be costly. That’s why our team chose to prepare this article content in order to help you see more clearly, learn about the different possible failures and establish your issue. To do this, we will first look at the normal running and usefulness of the injectors in your Land Rover Discovery, then at the possible causes from which an injector noise may come.
Purposes of the injectors
Injectors are a very fundamental element of the operation of your engine motor. They were introduced to the modern automobiles about 20 years ago. Before their appearance, 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 accurately (quantity of fuel injected, air/fuel mixture) via the analysis of the data compiled 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 get the best possible combustion in the cylinders.
The different reasons of a clicking or knocking noise based on the injectors of your Land Rover Discovery
Finding out injector noises on your Land Rover Discovery may come from different sources, we will now center on the potential triggers of these. Generally, the regular noise of a faulty injector is of the snap type. Here are the several origins of these noises and the solutions to be adopted to eliminate them. If you notice another clicking noise but it is not from your injectors, we recommend you to examine this article content about clicking noise on Land Rover Discovery to find the trigger.
The causes for injector clicking or knocking noise Land Rover Discovery
A clicking or knocking noise from your injectors can be justified by different causes. Indeed, the injectors of your Land Rover Discovery have three main missions, to control the vaporisation of the fuel, i.e., to transform the liquid into “gas” during injection, to ease its combustion. Then, its mission is to control the air/fuel dosage and finally the homogeneity of the mixture, always with the aim of improving combustion. If one of these three features is modified, 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. The main trigger of these trouble generally originates from a particle that gets into the injectors. The precision of the injector being in the nanometer range, any possible blockage will inevitably cause a malfunction of the injector. If after verifying, this noise originates from another component of the engine of your Land Rover Discovery, check this article content for more infos.
The effects of injector noise on Land Rover Discovery
Now that we have reviewed the several causes for injector noise on your Land Rover Discovery, we will end by stating the possible consequences of malfunctioning one or more of your injectors. Whether only one is blocked, or damaged, or your entire fuel rail is involved, you cannot escape these effects which can fairly quickly become considerable….
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 basic consequences felt by drivers is a noticeable 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 fairly quickly damage your cylinders or pistons and your engine may tighten.
Here are three little suggestions 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>
