It is never pleasant to hear an injector noise on your Lexus GX. It is a noise that arises regularly, usually when you accelerate or your engine is idling. However, this indication may be linked to multiple kind of problems with your automobile injectors. It may not be anything major, but when a persistent noise comes out, you have to be sure. Most importantly since repairing your Lexus GX’s injectors can be costly. That’s why our team chose to produce this content page 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 Lexus GX, then at the possible triggers from which an injector noise may come.
Functions of the injectors
Injectors are a very important element of the operation of your engine motor. 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 possibility, 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 collected 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 obtain the best possible combustion in the cylinders.
The different reasons of a clicking or knocking noise coming from the injectors of your Lexus GX
Finding out injector noises on your Lexus GX may come from different locations, we will now focus on the potential triggers of these. Generally, the common noise of a faulty injector is of the snap type. Here are the several origins of these noises and the solutions to be put into practice to eliminate them. If you hear another clicking noise but it is not from your injectors, we advise you to go through this content page about clicking noise on Lexus GX to discover the cause.
The explanations for injector clicking or knocking noise Lexus GX
A clicking or knocking noise from your injectors can be justified by different explanations. In fact, the injectors of your Lexus GX have three main tasks, to control the vaporisation of the fuel, i.e., to transform the liquid into “gas” during injection, to facilitate its combustion. Then, its task is to manage the air/fuel dosage and at last the homogeneity of the mixture, always with the aim of improving combustion. If one of these three functions is modified, the main purpose 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 Lexus GX. The main cause of these concerns commonly comes from a particle that gets into the injectors. The accuracy of the injector being in the nanometer range, any possible obstruction will inevitably end in a malfunction of the injector. If after verifying, this noise comes from another part of the engine of your Lexus GX, check this content page for more infos.
The consequences of injector noise on Lexus GX
Now that we have analyzed the diverse reasons for injector noise on your Lexus GX, we will end by stating the possible effects of malfunctioning one or more of your injectors. Whether only one is clogged, or damaged, or your entire fuel rail is involved, you cannot escape these repercussions which can fairly quickly become severe….
First, you risk destroying your exhaust system 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 effects noticed by drivers is a significant 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 fairly quickly damage your cylinders or pistons and your engine may tighten.
Here are three little recommendations 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>
