It is never pleasant to listen an injector noise on your Acura MDX. It is a noise that happens frequently, usually when you accelerate or your engine is idling. However, this sign may be related to different types of concerns with your car injectors. It may not be anything severe, but when a persistent noise comes out, you have to be sure. Specifically since repairing your Acura MDX’s injectors can be expensive. That’s why our team chose to produce this content page in order to support you see more clearly, learn about the different conceivable failures and identify your trouble. To do this, we will first look at the normal functioning and usefulness of the injectors in your Acura MDX, then at the conceivable reasons from which an injector noise may come.
Functions of the injectors
Injectors are a very fundamental component of the operation of your engine. They were introduced to the modern automobiles 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 precisely (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 aim 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 reasons of a clicking or knocking noise coming from the injectors of your Acura MDX
Listening injector noises on your Acura MDX may come from different locations, we will now concentrate on the potential causes of these. In most cases, the typical 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 eliminate them. If you listen another clicking noise but it is not from your injectors, we encourage you to examine this content page about clicking noise on Acura MDX to locate the reason.
The causes for injector clicking or knocking noise Acura MDX
A clicking or knocking noise from your injectors can be justified by different causes. Indeed, the injectors of your Acura MDX 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 task is to control the air/fuel dosage and at last the homogeneity of the mixture, always with the goal of improving combustion. If one of these three attributes is modified, the main role of the injectors will be disturbed and this will lead to poor combustion. This bad combustion will be a violent explosion in the cylinders because 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 MDX. The main reason of these situations in most cases originates from a particle that gets into the injectors. The accuracy of the injector being in the nanometer range, any possible obstruction will inevitably cause a malfunction of the injector. If after verifying, this noise originates from another part of the engine of your Acura MDX, check this content page for more informations.
The effects of injector noise on Acura MDX
Now that we have examined the several reasons for injector noise on your Acura MDX, we will end by stating the possible side effects 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 side effects which can quickly become considerable….
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 basic repercussions experienced by drivers is a severe loss of power. Indeed, if your engine is running on 3 out of 4 cylinders for example, you will surely have a loss of power
Finally, you risk deteriorating one of your pistons or your engine. Poor combustion will quickly harm your cylinders or pistons and your engine may tighten.
Here are three little suggestions to limit the risks connected with 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>
