It is never relaxing to hear an injector noise on your Buick Enclave. It is a noise that comes up frequently, usually when you accelerate or your engine is idling. However, this sign may be linked to multiple kind of trouble with your vehicle injectors. It may not be anything major, but when a continuing noise comes out, you have to be sure. Most importantly since replacing your Buick Enclave’s injectors can be costly. That’s why our team chose to prepare this article in order to support you see more clearly, learn about the different conceivable failures and distinguish your trouble. To do this, we will first look at the normal functioning and usefulness of the injectors in your Buick Enclave, then at the conceivable triggers from which an injector noise may come.injector-noise-buick-enclave

Functions of the injectors

Injectors are a very important element of the operation of your engine motor. They were introduced to the modern cars about 20 years ago. Before their introduction, 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 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 received from the various sensors equipping the vehicle (engine temperature, acceleration level, engine speed, etc.). Their goal 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 origins of a clicking or knocking noise coming from the injectors of your Buick Enclave

Finding out injector noises on your Buick Enclave may result from different locations, we will now center on the potential causes of these. Generally, the usual noise of a faulty injector is of the snap type. Here are the several origins of these noises and the solutions to be used to prevent them. If you hear another clicking noise but it is not from your injectors, we suggest you to read this article about clicking noise on Buick Enclave to discover the reason.

The explanations for injector clicking or knocking noise Buick Enclave

A clicking or knocking noise from your injectors can be explained for different explanations. In fact, the injectors of your Buick Enclave have three main missions, to manage the vaporisation of the fuel, i.e., to convert the liquid into “gas” during injection, to ease its combustion. Then, its goal is to control the air/fuel dosage and at last the homogeneity of the mixture, always with the objective of improving combustion. If one of these three characteristics 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 as a consequence of bad timing, or a bad quantity of mixture or finally an inhomogeneous mixture and will induce thoses knocking or clicking noises on your Buick Enclave. The main reason of these concerns generally originates from a particle that gets into the injectors. The accuracy of the injector being in the nanometer range, any possible obstruction will inevitably cause a malfunction of the injector. If after verifying, this noise originates from another part of the engine of your Buick Enclave, check this article for more informations.

The consequences of injector noise on Buick Enclave

Now that we have examined the different causes for injector noise on your Buick Enclave, we will end by stating the possible effects of malfunctioning one or more of your injectors. Whether only one is clogged, or broken, or your entire fuel rail is involved, you cannot escape these consequences 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 basic 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 obviously have a loss of power
Finally, you risk degrading 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 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>
