It is rarely ever relaxing to hear an injector noise on your Buick Lucerne. It is a noise that comes up regularly, usually when you accelerate or your engine is idling. However, this symptom may be linked to different types of complications with your car injectors. It may not be anything severe, but when a persistent noise appears, you have to be sure. Most importantly since fixing your Buick Lucerne’s injectors can be expensive. That’s why our team decided to create this article content in order to support you see more clearly, learn about the different possible failures and establish your trouble. To do this, we will first look at the normal running and usefulness of the injectors in your Buick Lucerne, then at the possible reasons from which an injector noise may come.
Attributes of the injectors
Injectors are a very vital component of the operation of your engine motor. They were introduced 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 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 car (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 causes of a clicking or knocking noise coming from the injectors of your Buick Lucerne
Finding out injector noises on your Buick Lucerne may result from different locations, we will now look into the potential triggers of these. In most cases, the common noise of a faulty injector is of the snap type. Here are the different origins of these noises and the solutions to be adopted to prevent them. If you hear another clicking noise but it is not from your injectors, we recommend you to examine this article content about clicking noise on Buick Lucerne to discover the cause.
The causes for injector clicking or knocking noise Buick Lucerne
A clicking or knocking noise from your injectors can be explained for different causes. Indeed, the injectors of your Buick Lucerne have three main tasks, 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 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 functions is modified, the main purpose of the injectors will be disrupted 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 provoke thoses knocking or clicking noises on your Buick Lucerne. The main cause of these concerns commonly originates from a particle that gets into the injectors. The precision of the injector being in the nanometer range, any possible blockage will inevitably lead to a malfunction of the injector. If after verifying, this noise originates from another component of the engine of your Buick Lucerne, have a look at this article content for more infos.
The end result of injector noise on Buick Lucerne
Now that we have reviewed the several reasons for injector noise on your Buick Lucerne, we will end by stating the possible side 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 effects which can fairly 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 regular effects felt by drivers is a significant loss of power. Indeed, 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 tips to limit the risks linked 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>
