It is never relaxing to listen to an injector noise on your Land Rover Freelander. It is a noise that happens continually, usually when you accelerate or your engine is idling. However, this indication may be linked to several types of problems with your vehicle injectors. It may not be anything severe, but when a repeated noise arises, you have to be sure. Especially since fixing your Land Rover Freelander’s injectors can be costly. That’s why our team decided to produce this content in order to help you see more clearly, learn about the different conceivable failures and distinguish your problem. To do this, we will first look at the normal running and usefulness of the injectors in your Land Rover Freelander, then at the conceivable reasons from which an injector noise may come.
Functions of the injectors
Injectors are a very useful part of the operation of your engine unit. They were introduced 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 accurately (quantity of fuel injected, air/fuel mixture) via the analysis of the data collected 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 triggers of a clicking or knocking noise coming from the injectors of your Land Rover Freelander
Finding out injector noises on your Land Rover Freelander may result from different locations, we will now look into the potential causes of these. In most cases, the regular noise of a faulty injector is of the snap type. Here are the different sources of these noises and the solutions to be implemented to prevent them. If you listen to another clicking noise but it is not from your injectors, we recommend you to read this content about clicking noise on Land Rover Freelander to locate the reason.
The reasons for injector clicking or knocking noise Land Rover Freelander
A clicking or knocking noise from your injectors can be explained for different reasons. In fact, the injectors of your Land Rover Freelander 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 objective 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 functions is altered, the main functionality of the injectors will be disrupted and this will lead to poor combustion. This bad combustion will be a violent explosion in the cylinders due to 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 Freelander. The main reason of these trouble commonly comes from a particle that gets into the injectors. The precision of the injector being in the nanometer range, any possible blockage will inevitably end up in a malfunction of the injector. If after verifying, this noise comes from another part of the engine of your Land Rover Freelander, read this content for more informations.
The effects of injector noise on Land Rover Freelander
Now that we have examined the diverse reasons for injector noise on your Land Rover Freelander, we will end by stating the possible consequences 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 quickly become considerable….
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 common repercussions noticed by drivers is a distinctive 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 quickly affect 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>
