It is hardly ever pleasant to experience an injector noise on your Jaguar XE. It is a noise that appears frequently, usually when you accelerate or your engine is idling. However, this sign may be linked to multiple types of complications with your car injectors. It may not be anything severe, but when a frequent noise shows up, you have to be sure. Most importantly since fixing your Jaguar XE’s injectors can be expensive. That’s why our team chose to write this content in order to support you see more clearly, learn about the different plausible failures and determine your issue. To do this, we will first look at the normal functioning and usefulness of the injectors in your Jaguar XE, then at the plausible reasons from which an injector noise may come.injector-noise-jaguar-xe

Benefits of the injectors

Injectors are a very fundamental part of the operation of your engine motor. They were launched to the modern cars about 20 years ago. Before their arrival, more conventional carburettor-type intake systems were employed, 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 precisely (quantity of fuel injected, air/fuel mixture) via the analysis of the data obtained from the various sensors equipping the car (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 caused by the injectors of your Jaguar XE

Listening injector noises on your Jaguar XE may come from different locations, we will now concentrate on the potential causes of these. Generally, the usual noise of a faulty injector is of the snap type. Here are the several sources of these noises and the solutions to be implemented to prevent them. If you experience another clicking noise but it is not from your injectors, we recommend you to browse this content about clicking noise on Jaguar XE to discover the reason.

The reasons for injector clicking or knocking noise Jaguar XE

A clicking or knocking noise from your injectors can be justified by different reasons. In fact, the injectors of your Jaguar XE 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 manage the air/fuel dosage and at last the homogeneity of the mixture, always with the target of improving combustion. If one of these three tasks 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 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 Jaguar XE. The main reason of these situations in most cases comes from a particle that gets into the injectors. The precision of the injector being in the nanometer range, any possible obstruction will inevitably result in a malfunction of the injector.

The consequences of injector noise on Jaguar XE

Now that we have reviewed the different reasons for injector noise on your Jaguar XE, we will end by stating the possible side effects 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 side effects which can promptly 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 regular effects felt 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 inevitably have a loss of power
Finally, you risk degrading one of your pistons or your engine. Poor combustion will promptly affect your cylinders or pistons and your engine may tighten.
Here are three little tips to limit the risks connected 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>
