It is hardly ever pleasurable to perceive an injector noise on your Nissan X-trail. It is a noise that arises regularly, usually when you accelerate or your engine is idling. However, this warning sign may be connected to different kind of problems with your automobile injectors. It may not be anything serious, but when a continuing noise appears, you have to be sure. Most importantly since fixing your Nissan X-trail’s injectors can be expensive. That’s why our team chose to compose this article content in order to help you see more clearly, learn about the different plausible failures and establish your trouble. To do this, we will first look at the normal functioning and usefulness of the injectors in your Nissan X-trail, then at the plausible reasons from which an injector noise may come.
Purposes of the injectors
Injectors are a very important element of the operation of your engine. They were brought in 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 ability, 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 automobile (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 caused by the injectors of your Nissan X-trail
Finding out injector noises on your Nissan X-trail may originate from different origins, we will now center on the potential triggers of these. In most cases, the typical noise of a faulty injector is of the snap type. Here are the different sources of these noises and the solutions to be adopted to prevent them. If you perceive another clicking noise but it is not from your injectors, we suggest you to read this article content about clicking noise on Nissan X-trail to discover the cause.
The causes for injector clicking or knocking noise Nissan X-trail
A clicking or knocking noise from your injectors can be explained for different causes. Indeed, the injectors of your Nissan X-trail have three main missions, to control the vaporisation of the fuel, i.e., to convert the liquid into “gas” during injection, to ease its combustion. Then, its objective is to deal with the air/fuel dosage and finally the homogeneity of the mixture, always with the target of improving combustion. If one of these three features is modified, the main role 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 provoke thoses knocking or clicking noises on your Nissan X-trail. 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 produce a malfunction of the injector. If after verifying, this noise comes from another component of the engine of your Nissan X-trail, check this article content for more informations.
The repercussions of injector noise on Nissan X-trail
Now that we have analyzed the several reasons for injector noise on your Nissan X-trail, we will end by stating the possible end result 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 repercussions which can fairly quickly become serious….
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 effects experienced by drivers is a noticeable loss of power. Indeed, if your engine is running on 3 out of 4 cylinders for example, you will inevitably 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 recommendations 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 changing your diesel fuel filter regularly>
