It is never pleasant to hear an injector noise on your Acura ILX. It is a noise that appears repeatedly, usually when you accelerate or your engine is idling. However, this indicator may be linked to several types of problems with your automobile injectors. It may not be anything severe, but when a continuing noise happens, you have to be sure. Most importantly since repairing your Acura ILX’s injectors can be costly. That’s why our team decided to prepare this article in order to help you see more clearly, learn about the different possible failures and determine your issue. To do this, we will first look at the normal functioning and usefulness of the injectors in your Acura ILX, then at the possible triggers from which an injector noise may come.
Functions of the injectors
Injectors are a very vital part of the operation of your engine motor. They were launched to the modern automobiles about 20 years ago. Before their appearance, 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 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 accumulated from the various sensors equipping the automobile (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 get the best possible combustion in the cylinders.
The different origins of a clicking or knocking noise coming from the injectors of your Acura ILX
Experiencing injector noises on your Acura ILX may come from different locations, we will now concentrate on the potential causes of these. In most cases, 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 article about clicking noise on Acura ILX to locate the trigger.
The explanations for injector clicking or knocking noise Acura ILX
A clicking or knocking noise from your injectors can be explained for different explanations. In fact, the injectors of your Acura ILX have three main tasks, to control the vaporisation of the fuel, i.e., to transform 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 aim of improving combustion. If one of these three attributes 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 induce thoses knocking or clicking noises on your Acura ILX. The main trigger of these trouble in most cases comes from a particle that gets into the injectors. The accuracy of the injector being in the nanometer range, any possible blockage will inevitably result in a malfunction of the injector. If after verifying, this noise comes from another component of the engine of your Acura ILX, check this article for more informations.
The effects of injector noise on Acura ILX
Now that we have reviewed the different reasons for injector noise on your Acura ILX, we will end by stating the possible effects of malfunctioning one or more of your injectors. Whether only one is obstructed, or broken, or your entire fuel rail is involved, you cannot escape these side effects 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 significant 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 promptly damage your cylinders or pistons and your engine may tighten.
Here are three little suggestions to limit the risks relating 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>
