It is hardly ever enjoyable to perceive an injector noise on your Acura RDX. It is a noise that comes up continually, usually when you accelerate or your engine is idling. However, this indicator may be relating to multiple sort of problems with your vehicle injectors. It may not be anything severe, but when a continuing noise happens, you have to be sure. Specifically since fixing your Acura RDX’s injectors can be expensive. That’s why our team decided to compose this article content in order to support you see more clearly, learn about the different possible failures and identify your problem. To do this, we will first look at the normal functioning and usefulness of the injectors in your Acura RDX, then at the possible triggers from which an injector noise may come.injector-noise-acura-rdx

Purposes of the injectors

Injectors are a very important component of the operation of your engine. They were launched to the modern vehicles about 20 years ago. Before their appearance, 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 precisely (quantity of fuel injected, air/fuel mixture) via the analysis of the data accumulated from the various sensors equipping the vehicle (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 caused by the injectors of your Acura RDX

Listening injector noises on your Acura RDX may originate from different sources, we will now concentrate on the potential triggers of these. In most cases, the usual noise of a faulty injector is of the snap type. Here are the several sources of these noises and the solutions to be applied to stop them. If you perceive another clicking noise but it is not from your injectors, we advise you to examine this article content about clicking noise on Acura RDX to find the trigger.

The reasons for injector clicking or knocking noise Acura RDX

A clicking or knocking noise from your injectors can be explained for different reasons. Indeed, the injectors of your Acura RDX have three main missions, to control the vaporisation of the fuel, i.e., to convert the liquid into “gas” during injection, to facilitate its combustion. Then, its objective is to control the air/fuel dosage and at last the homogeneity of the mixture, always with the aim of improving combustion. If one of these three characteristics is modified, 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 provoke thoses knocking or clicking noises on your Acura RDX. The main trigger of these concerns usually comes from a particle that gets into the injectors. The precision of the injector being in the nanometer range, any possible blockage will inevitably produce a malfunction of the injector.

The repercussions of injector noise on Acura RDX

Now that we have reviewed the different causes for injector noise on your Acura RDX, we will end by stating the possible consequences of malfunctioning one or more of your injectors. Whether only one is obstructed, or damaged, or your entire fuel rail is involved, you cannot escape these effects which can almost instantly become major….
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 common effects felt by drivers is a distinctive loss of power. Indeed, 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 almost instantly 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 swapping your diesel fuel filter regularly>
