It is rarely ever pleasant to listen to an injector noise on your Toyota FJ Cruiser. It is a noise that arises regularly, usually when you accelerate or your engine is idling. However, this warning sign may be related to different sort of complications with your car injectors. It may not be anything major, but when a repeated noise arises, you have to be sure. Most importantly since fixing your Toyota FJ Cruiser’s injectors can be costly. That’s why our team decided to write this content page in order to help you see more clearly, learn about the different plausible failures and identify your issue. To do this, we will first look at the normal functioning and usefulness of the injectors in your Toyota FJ Cruiser, then at the plausible reasons from which an injector noise may come.
Functions of the injectors
Injectors are a very useful component of the operation of your engine motor. They were launched to the modern vehicles 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 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 collected from the various sensors equipping the car (engine temperature, acceleration level, engine speed, etc.). Their objective 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 caused by the injectors of your Toyota FJ Cruiser
Hearing injector noises on your Toyota FJ Cruiser may come from different locations, we will now center on the potential causes of these. In general, the regular noise of a faulty injector is of the snap type. Here are the several sources of these noises and the solutions to be adopted to get rid of them. If you listen to another clicking noise but it is not from your injectors, we encourage you to examine this content page about clicking noise on Toyota FJ Cruiser to discover the trigger.
The explanations for injector clicking or knocking noise Toyota FJ Cruiser
A clicking or knocking noise from your injectors can be explained for different explanations. In fact, the injectors of your Toyota FJ Cruiser have three main tasks, to manage the vaporisation of the fuel, i.e., to convert the liquid into “gas” during injection, to facilitate its combustion. Then, its goal is to deal with the air/fuel dosage and finally the homogeneity of the mixture, always with the goal of improving combustion. If one of these three tasks is altered, 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 trigger thoses knocking or clicking noises on your Toyota FJ Cruiser. The main trigger of these concerns commonly originates 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 originates from another element of the engine of your Toyota FJ Cruiser, browse this content page for more informations.
The side effects of injector noise on Toyota FJ Cruiser
Now that we have analyzed the diverse reasons for injector noise on your Toyota FJ Cruiser, 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 promptly 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 regular consequences noticed by drivers is a serious 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 deteriorating one of your pistons or your engine. Poor combustion will promptly damage your cylinders or pistons and your engine may tighten.
Here are three little tips 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 swapping your diesel fuel filter regularly>
